Jevantique

This section provides information on the proper use of a number of products that contain ethinyl estradiol and norethindrone. It may not be specific to Jevantique. Please read with care.

To make using oral contraceptives as safe and reliable as possible, you should understand how and when to take them and what effects may be expected.

This medicine comes with patient instructions. Read and follow these instructions carefully. Ask your doctor or pharmacist if you have any questions.

This medicine is available in blister packs with a Dialpak® tablet dispenser. Each blister pack contains 28 tablets with different colors that need to be taken in the same order as directed on the blister pack.

When you begin using this medicine, your body will require at least 7 days to adjust before a pregnancy will be prevented. Use a second form of contraception, such as a condom, spermicide, or diaphragm, for the first 7 days of your first cycle of pills.

Take this medicine at the same time each day. Birth control pills work best when no more than 24 hours pass between doses.

Do not skip or delay taking your pill by more than 24 hours. If you miss a dose, you could get pregnant. Ask your doctor for ways to help you remember to take your pills or about using another method of birth control.

You may feel sick or nauseated, especially during the first few months that you take this medicine. If your nausea is continuous and does not go away, call your doctor.

Dosing

The dose of this medicine will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of this medicine. If your dose is different, do not change it unless your doctor tells you to do so.

The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.

Your doctor may ask you to begin your dose on the first day of your menstrual period (called Day 1 start) or on the first Sunday after your menstrual period starts (called Sunday start). When you begin on a certain day it is important that you follow that schedule, even if you miss a dose. Do not change your schedule on your own. If the schedule that you use is not convenient, check with your doctor about changing it. For a Sunday start, you need to use another form of birth control (eg, condom, diaphragm, spermicide) for the first 7 days.

You should begin your next and all subsequent 28-day regimens of therapy on the same day of the week as the first regimen began and follow the same schedule.

• For oral dosage form (tablets):
  • For contraception (to prevent pregnancy):
    • Adults and teenagers—
      • Modicon®: One white tablet taken at the same time each day for 21 consecutive days followed by one green (inert) tablet daily for 7 days per menstrual cycle.
      • Ortho-novum®: One white or peach tablet taken at the same time each day for 21 consecutive days followed by one green (inert) tablet daily for 7 days per menstrual cycle.
    • Children—Use and dose must be determined by your doctor.

Missed Dose

Call your doctor or pharmacist for instructions.

This medicine has specific patient instructions on what to do if you miss a dose. Read and follow these instructions carefully and call your doctor if you have any questions.

Use a second form of birth control for 7 days after you miss a dose, to prevent pregnancy.

Make sure your doctor knows if you miss your period 2 months in a row, because this could mean that you are pregnant.

You may not have a period for that month if you miss more than one dose or change your schedule.

You could have light bleeding or spotting if you do not take a pill on time. The more pills you miss, the more likely you are to have bleeding.

Storage

Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light. Keep from freezing.

Keep out of the reach of children.

Do not keep outdated medicine or medicine no longer needed.

Ask your healthcare professional how you should dispose of any medicine you do not use.

It is very important that your doctor check your progress at regular visits to make sure this medicine is working properly and does not cause unwanted effects. These visits will usually be every 6 to 12 months, but some doctors require them more often. Your doctor may also want to check your blood pressure while taking this medicine.

Although you are using this medicine to prevent pregnancy, you should know that using this medicine while you are pregnant could harm the unborn baby. If you think you have become pregnant while using the medicine, tell your doctor right away. Make sure your doctor knows if you have had a baby within 4 weeks before you start using this medicine.

Vaginal bleeding of various amounts may occur between your regular menstrual periods during the first 3 months of use. This is sometimes called spotting when slight, or breakthrough bleeding when heavier.

• If this should occur, continue with your regular dosing schedule.
• The bleeding usually stops within 1 week. Check with your doctor if the bleeding continues for more than 1 week.
• If the bleeding continues after you have been taking hormonal contraceptives on schedule and for more than 3 months, check with your doctor.

Check with your doctor right away if you miss a menstrual period. Missed periods may occur if you skip one or more tablets and have not taken your pills exactly as directed. If you miss two periods in a row, talk to your doctor. You might need a pregnancy test.

If you suspect that you may be pregnant, stop taking this medicine immediately and check with your doctor.

Do not use this medicine if you smoke cigarettes or if you are over 35 years of age. If you smoke while using birth control pills, you increase your risk of having a blood clot, heart attack, or stroke. Your risk is even higher if you are over age 35, if you have diabetes, high blood pressure, high cholesterol, or if you are overweight. Talk with your doctor about ways to stop smoking. Keep your diabetes under control. Ask your doctor about diet and exercise to control your weight and blood cholesterol level.

Using this medicine may increase your risk of having blood clotting problems. Check with your doctor right away if you have pain in the chest, groin, or legs, especially the calves, difficulty with breathing, a sudden, severe headache, slurred speech, a sudden, unexplained shortness of breath, a sudden unexplained shortness of breath, a sudden loss of coordination, or vision changes while using this medicine.

Using this medicine may increase your risk of breast cancer or cervical cancer. Talk with your doctor about this risk. Check with your doctor immediately if your experience abnormal vaginal bleeding.

Check with your doctor immediately if you wear contact lenses or if blurred vision, difficulty in reading, or any other change in vision occurs during or after treatment. Your doctor may want an eye doctor to check your eyes.

Check with your doctor right away if you have pain or tenderness in the upper stomach, dark urine or pale stools, or yellow eyes or skin. These could be symptoms of a serious liver problem.

Using this medicine may increase your risk for gallbladder surgery. Talk with your doctor about this risk.

Check with your doctor before refilling an old prescription, especially after a pregnancy. You will need another physical examination and your doctor may change your prescription.

Make sure any doctor or dentist who treats you knows that you are using this medicine. The results of some medical tests may be affected by this medicine. You may also need to stop using this medicine at least 4 weeks before and 2 weeks after having major surgery.

Do not eat grapefruit or drink grapefruit juice while you are using this medicine. Grapefruit and grapefruit juice may change the amount of this medicine that is absorbed in the body.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal (eg, St. John's wort) or vitamin supplements.

JevantiqueTM (Norethindrone Acetate and Ethinyl Estradiol Tablets) is a continuous dosage regimen of a progestin-estrogen combination for oral administration.

The following strength of JevantiqueTM tablets is available:

JevantiqueTM (1 mg/5 mcg): Each white D-shaped tablet contains 1 mg norethindrone acetate and 5 mcg ethinyl estradiol.

Each tablet also contains the following inactive ingredients: calcium stearate, lactose monohydrate, microcrystalline cellulose, and cornstarch.

The structural formulas are as follows:

Ethinyl Estradiol [19-Norpregna-1,3,5(10)-trien-20-yne-3,17-diol, (17α)-]
Molecular Weight: 296.41
Molecular Formula: C20H24O2

Norethindrone Acetate [19-Norpregn-4-en-20-yn-3-one, 17-(acetyloxy)-, (17α)-]
Molecular Weight: 340.47
Molecular Formula: C22H28O3

Endogenous estrogens are largely responsible for the development and maintenance of the female reproductive system and secondary sexual characteristics. Although circulating estrogens exist in a dynamic equilibrium of metabolic interconversions, estradiol is the principal intracellular human estrogen and is substantially more potent than its metabolites estrone and estriol at the receptor level.

The primary source of estrogen in normally cycling adult women is the ovarian follicle, which secretes 70 to 500 mcg of estradiol daily, depending on the phase of the menstrual cycle. After menopause, most endogenous estrogen is produced by conversion of androstenedione, secreted by the adrenal cortex, to estrone by peripheral tissues. Thus, estrone and the sulfate conjugated form, estrone sulfate, are the most abundant circulating estrogens in postmenopausal women. The pharmacologic effects of ethinyl estradiol are similar to those of endogenous estrogens.

Estrogens act through binding to nuclear receptors in estrogen-responsive tissues. To date, two estrogen receptors have been identified. These vary in proportion from tissue to tissue.

Circulating estrogens modulate the pituitary secretion of the gonadotropins, luteinizing hormone (LH) and follicle stimulating hormone (FSH) through a negative feedback mechanism. Estrogens act to reduce the elevated levels of these hormones seen in postmenopausal women.

Progestin compounds enhance cellular differentiation and generally oppose the actions of estrogens by decreasing estrogen receptor levels, increasing local metabolism of estrogens to less active metabolites, or inducing gene products that blunt cellular responses to estrogen. Progestins exert their effects in target cells by binding to specific progesterone receptors that interact with progesterone response elements in target genes. Progesterone receptors have been identified in the female reproductive tract, breast, pituitary, hypothalamus, bone, skeletal tissue and central nervous system. Progestins produce similar endometrial changes to those of the naturally occurring hormone progesterone.

Pharmacokinetics

Norethindrone acetate (NA) is completely and rapidly deacetylated to norethindrone after oral administration, and the disposition of norethindrone acetate is indistinguishable from that of orally administered norethindrone. Norethindrone acetate and ethinyl estradiol (EE) are rapidly absorbed from JevantiqueTM tablets, with maximum plasma concentrations of norethindrone and ethinyl estradiol generally occurring 1 to 2 hours postdose. Both are subject to first-pass metabolism after oral dosing, resulting in an absolute bioavailability of approximately 64% for norethindrone and 55% for ethinyl estradiol. Bioavailability of JevantiqueTM tablets is similar to that from solution for norethindrone and slightly less for ethinyl estradiol. Administration of JevantiqueTM tablets with a high fat meal decreases rate but not extent of ethinyl estradiol absorption. The extent of norethindrone absorption is increased by 27% following administration of JevantiqueTM tablets with food.

The full pharmacokinetic profile of JevantiqueTM tablets was not characterized due to assay sensitivity limitations. However, the multiple-dose pharmacokinetics were studied at a dose of 1 mg NA/10 mcg EE in 18 post-menopausal women. Mean plasma concentrations are shown below (Figure 1) and pharmacokinetic parameters are found in Table 1. Based on a population pharmacokinetic analysis, mean steady-state concentrations of norethindrone for 1 mg NA/5 mcg EE and 1/10 are slightly more than proportional to dose when compared to 0.5 mg NA/2.5 mcg EE tablets. It can be explained by higher sex hormone binding globulin (SHBG) concentrations. Mean steady-state plasma concentrations of ethinyl estradiol for the JevantiqueTM 1/5 tablets are proportional to dose, but there is a less than proportional increase in steady-state concentrations for the NA/EE 1/10 tablet.

Figure 1. Mean Steady-State (Day 87) Plasma Norethindrone and Ethinyl Estradiol Concentrations Following Continuous Oral Administration of 1 mg NA/10 mcg EE Tablets

Based on a population pharmacokinetic analysis, average steady-state concentrations (Css) of norethindrone and ethinyl estradiol for JevantiqueTM 1/5 tablets are estimated to be 2.6 ng/mL and 11.4 pg/mL, respectively. The pharmacokinetics of ethinyl estradiol and norethindrone acetate were not affected by age, (age range 40-62 years), in the postmenopausal population studied.

The distribution of exogenous estrogens is similar to that of endogenous estrogens. Estrogens are widely distributed in the body and are generally found in higher concentrations in the sex hormone target organs. Estrogens circulate in the blood largely bound to sex hormone binding globulin (SHBG) and albumin.

Volume of distribution of norethindrone and ethinyl estradiol ranges from 2 to 4 L/kg. Plasma protein binding of both steroids is extensive (>95%); norethindrone binds to both albumin and sex hormone binding globulin (SHBG), whereas ethinyl estradiol binds only to albumin. Although ethinyl estradiol does not bind to SHBG, it induces SHBG synthesis.

Exogenous estrogens are metabolized in the same manner as endogenous estrogens. Circulating estrogens exist in a dynamic equilibrium of metabolic interconversions. These transformations take place mainly in the liver. Estradiol is converted reversibly to estrone, and both can be converted to estriol, which is the major urinary metabolite. Estrogens also undergo enterohepatic recirculation via sulfate and glucuronide conjugation in the liver, biliary secretion of conjugates into the intestine, and hydrolysis in the gut followed by reabsorption. In postmenopausal women, a significant proportion of the circulating estrogens exist as sulfate conjugates, especially estrone sulfate, which serves as a circulating reservoir for the formation of more active estrogens.

Norethindrone undergoes extensive biotransformation, primarily via reduction, followed by sulfate and glucuronide conjugation. The majority of metabolites in the circulation are sulfates, with glucuronides accounting for most of the urinary metabolites. A small amount of norethindrone acetate is metabolically converted to ethinyl estradiol, such that exposure to ethinyl estradiol following administration of 1 mg of norethindrone acetate is equivalent to oral administration of 2.8 mcg ethinyl estradiol. Ethinyl estradiol is also extensively metabolized, both by oxidation and by conjugation with sulfate and glucuronide. Sulfates are the major circulating conjugates of ethinyl estradiol and glucuronides predominate in urine. The primary oxidative metabolite is 2-hydroxy ethinyl estradiol, formed by the CYP3A4 isoform of cytochrome P450. Part of the first-pass metabolism of ethinyl estradiol is believed to occur in gastrointestinal mucosa. Ethinyl estradiol may undergo enterohepatic circulation.

Estradiol, estrone, and estriol are excreted in the urine along with glucuronide and sulfate conjugates.

Norethindrone and ethinyl estradiol are excreted in both urine and feces, primarily as metabolites. Plasma clearance values for norethindrone and ethinyl estradiol are similar (approximately 0.4 L/hr/kg). Steady-state elimination half-lives of norethindrone and ethinyl estradiol following administration of 1 mg NA/10 mcg EE tablets are approximately 13 hours and 24 hours, respectively.

Special Populations

JevantiqueTM is not indicated in children.

The pharmacokinetics of JevantiqueTM have not been studied in a geriatric population.

The effect of race on the pharmacokinetics of JevantiqueTM has not been studied.

The effect of renal disease on the disposition of JevantiqueTM has not been evaluated. In premenopausal women with chronic renal failure undergoing peritoneal dialysis who received multiple doses of an oral contraceptive containing ethinyl estradiol and norethindrone, plasma ethinyl estradiol concentrations were higher and norethindrone concentrations were unchanged compared to concentrations in premenopausal women with normal renal function (see PRECAUTIONS, Fluid Retention).

The effect of hepatic disease on the disposition of JevantiqueTM has not been evaluated. However, ethinyl estradiol and norethindrone may be poorly metabolized in patients with impaired liver function (see PRECAUTIONS).

Drug Interactions

See PRECAUTIONS, Drug Interactions.

In vitro and in vivo studies have shown that estrogens are metabolized partially by cytochrome P450 3A4 (CYP3A4). Therefore, inducers or inhibitors of CYP3A4 may affect estrogen drug metabolism. Inducers of CYP3A4 such as St. John’s Wort preparations (Hypericum perforatum), phenobarbital, carbamazepine, and rifampin may reduce plasma concentrations of estrogens, possibly resulting in a decrease in therapeutic effects and/or changes in the uterine bleeding profile. Inhibitors of CYP3A4 such as erythromycin, clarithromycin, ketoconazole, itraconazole, ritonavir and grapefruit juice may increase plasma concentrations of estrogens and may result in side effects.

Clinical Studies

A 12-week placebo-controlled, multicenter, randomized clinical trial was conducted in 266 symptomatic women who had at least 56 moderate to severe hot flushes during the week prior to randomization. On average, patients had 12 hot flushes per day upon study entry.

A total of 66 women were randomized to receive JevantiqueTM 1/5 and 66 women were randomized to the placebo group. JevantiqueTM 1/5 was shown to be statistically better than placebo at weeks 4 and 12 for relief of the frequency of moderate to severe vasomotor symptoms. See Table 2. In Table 3, JevantiqueTM 1/5 was shown to be statistically better than placebo at weeks 4 and 12 for relief of the severity of moderate to severe vasomotor symptoms.

A 2-year, placebo-controlled, multicenter, randomized clinical trial was conducted to determine the safety and efficacy of JevantiqueTM  on maintaining bone mineral density, protecting the endometrium, and to determine effects on lipids. A total of 1265 women were enrolled and randomized to either placebo, 0.2 mg NA/1 mcg EE, 0.5 mg NA/2.5 mcg EE, JevantiqueTM 1/5 and 1 mg NA/10 mcg EE or matching unopposed EE doses (1, 2.5, 5, or 10 mcg) for a total of 9 treatment groups. All participants received 1000 mg of calcium supplementation daily. Of the 1265 women randomized to the various treatment arms of this study, 137 were randomized to placebo, 146 to JevantiqueTM 1/5, 136 to NA/EE 0.5/2.5 and 141 to EE 5 mcg and 137 to EE 2.5 mcg. Of these, 134 placebo, 143 JevantiqueTM 1/5, 136 NA/EE 0.5/2.5, 139 EE 5 mcg and 137 EE 2.5 mcg had a baseline endometrial result. Baseline biopsies were classified as normal (in approximately 95% of subjects), or insufficient tissue (in approximately 5% of subjects). Follow-up biopsies were obtained in approximately 70-80% of patients in each arm after 12 and 24 months of therapy. Results are shown in Table 4.

The cumulative incidence of amenorrhea, defined as no bleeding or spotting obtained from subject recall, was evaluated over 12 months for JevantiqueTM 1/5 and placebo arms. Results are shown in Figure 2.

In the 2 year study, trabecular bone mineral density (BMD) was assessed at lumbar spine using quantitative computed tomography. A total of 419 postmenopausal primarily Caucasian women, aged 40 to 64 years, with intact uteri and non-osteoporotic bone mineral densities were randomized (1:1:1) to JevantiqueTM 1/5, NA/EE 0.5/2.5 or placebo. Approximately 75% of the subjects in each group completed the two-year study. All patients received 1000 mg calcium in divided doses. Vitamin D was not supplemented.

As shown in Figure 3, women treated with JevantiqueTM 1/5 had an average increase of 3.1% in lumbar spine BMD from baseline to Month 24. Women treated with placebo had an average decrease of –6.3%, in spinal BMD from baseline to Month 24. The differences in the changes from baseline to Month 24 in the JevantiqueTM 1/5 group compared with the placebo group were statistically significant.

Figure 3.

*It should be noted that when measured by QCT, BMD gains and losses are greater than when measured by dual X-ray absorptiometry (DXA). Therefore, the differences in the changes in BMD between the placebo and active drug treated groups will be larger when measured by QCT compared with DXA. Changes in BMD measured by DXA should not be compared with changes in BMD measured by QCT.

Women’s Health Initiative Studies

The Women’s Health Initiative (WHI) enrolled a total of 27,000 predominantly healthy postmenopausal women to assess the risks and benefits of either the use of oral 0.625 mg conjugated estrogens (CE) per day alone or the use of oral 0.625 mg conjugated estrogens plus 2.5 mg medroxyprogesterone acetate (MPA) per day compared to placebo in the prevention of certain chronic diseases. The primary endpoint was the incidence of coronary heart disease (CHD) (nonfatal myocardial infarction and CHD death), with invasive breast cancer as the primary adverse outcome studied. A “global index” included the earliest occurrence of CHD, invasive breast cancer, stroke, pulmonary embolism (PE), endometrial cancer, colorectal cancer, hip fracture, or death due to other cause. The study did not evaluate the effects of CE or CE/MPA on menopausal symptoms.

The CE/MPA substudy was stopped early because, according to the predefined stopping rule, the increased risk of breast cancer and cardiovascular events exceeded the specified benefits included in the “global index”. Results of the CE/MPA substudy, which included 16,608 women (average age of 63 years, range 50 to 79; 83.9% White, 6.5% Black, 5.5% Hispanic), after an average follow-up of 5.2 years are presented in Table 5 below:

For those outcomes included in the "global index", the absolute excess risks per 10,000 women-years in the group treated with CE/MPA were 7 more CHD events, 8 more strokes, 8 more PEs, and 8 more invasive breast cancers, while the absolute risk reductions per 10,000 women-years were 6 fewer colorectal cancers and 5 fewer hip fractures. The absolute excess risk of events included in the “global index” was 19 per 10,000 women-years. There was no difference between the groups in terms of all-cause mortality (see BOXED WARNING, WARNINGS, and PRECAUTIONS).

Women’s Health Initiative Memory Study

The Women’s Health Initiative Memory Study (WHIMS), a substudy of WHI, enrolled 4,532 predominantly healthy postmenopausal women 65 years of age and older (47% were age 65 to 69 years, 35% were 70 to 74 years, and 18% were 75 years of age and older) to evaluate the effects of CE/MPA (0.625 mg conjugated estrogens plus 2.5 mg medroxyprogesterone acetate) on the incidence of probable dementia (primary outcome) compared with placebo.

After an average follow-up of 4 years, 40 women in the estrogen/progestin group (45 per 10,000 women-years) and 21 in the placebo group (22 per 10,000 women-years) were  diagnosed with probable dementia. The relative risk of probable dementia in the hormone therapy group was 2.05 (95% CI, 1.21 to 3.48) compared to placebo. Differences between groups became apparent in the first year of treatment. It is unknown whether these findings apply to younger postmenopausal women. (see BOXED WARNING and WARNINGS, Dementia).

Use of estrogen, alone or in combination with a progestin, should be limited to the shortest duration consistent with treatment goals and risks for the individual woman. Patients should be reevaluated periodically as clinically appropriate (e.g., 3 to 6 month intervals) to determine if treatment is still necessary (see BOXED WARNING and WARNINGS). For women who have a uterus, adequate diagnostic measures, such as endometrial sampling, when indicated, should be undertaken to rule out malignancy in cases of undiagnosed persistent or recurring abnormal vaginal bleeding. Patients should be evaluated for breast abnormalities in accordance with good clinical practice.

Patients should be started at the lowest dose.

JevantiqueTM therapy consists of a single tablet taken once daily.

1.  For the Treatment of Moderate to Severe Vasomotor Symptoms associated with the menopause

JevantiqueTM should be given once daily for the treatment of moderate to severe vasomotor symptoms associated with the menopause. Patients should be reevaluated at 3 to 6 month intervals to determine if treatment is still necessary.

2.  For Prevention of Postmenopausal Osteoporosis

When prescribing solely of the prevention of postmenopausal osteoporosis, JevantiqueTM should only be prescribed to postmenopausal women who are at significant risk of osteoporosis. Non-estrogen medications should be carefully considered. Risk factors for osteoporosis include low bone mineral density, low estrogen levels, family history of osteoporosis, previous fracture, small frame (low BMI), light skin color, smoking, and alcohol intake. Patients should be treated with the lowest effective dose. This dose should be periodically reassessed by the healthcare provider. Response to therapy can be assessed during treatment by measuring biochemical markers of bone formation/resorption, and/or bone mineral density.

JevantiqueTM tablets are available in the following strength and package sizes:

Rx only

Keep this drug and all drugs out of the reach of children.

Store at 25° C (77° F); excursions permitted to 15 - 30° C (59 - 86° F) [see USP Controlled Room Temperature].

(Revised March 2011)

Please read this PATIENT INFORMATION before you start taking JevantiqueTM and each time you refill JevantiqueTM. There may be new information. This information does not take the place of talking to your healthcare provider about your medical condition or your treatment.

What is JevantiqueTM?

JevantiqueTM is medicine that contains two kinds of hormones, an estrogen and a progestin.

What is JevantiqueTM used for?

JevantiqueTM is used after menopause to:

• reduce moderate to severe hot flushes
  
  Estrogens are hormones made by a woman’s ovaries. The ovaries normally stop making estrogens when a woman is between 45 to 55 years old. This drop in body estrogen levels causes the “change of life” or menopause, the end of monthly menstrual periods. Sometimes both ovaries are removed during an operation before natural menopause takes place. The sudden drop in estrogen levels causes “surgical menopause”.
  
  When estrogen levels begin dropping, some women develop very uncomfortable symptoms, such as feelings of warmth in the face, neck, and chest, or sudden intense episodes of heat and sweating (“hot flashes” or “hot flushes”). In some women the symptoms are mild; in others they can be severe. You and your healthcare provider should talk regularly about whether you still need treatment with JevantiqueTM.

• help reduce your chances of getting osteoporosis (thin, weak bones)
  
  Osteoporosis from menopause is a thinning of the bones that makes them weaker and easier to break. If you use JevantiqueTM only to prevent osteoporosis from menopause, talk with your healthcare provider about whether a different treatment or medicine without estrogens might be better for you. You and your healthcare provider should talk regularly about whether you should continue with JevantiqueTM.
  
  Weight-bearing exercise, like walking or running, and taking calcium and vitamin D supplements may also lower your chances of getting postmenopausal osteoporosis. It is important to talk about exercise and supplements with your healthcare provider before starting them.

Who should not take JevantiqueTM?

Do not take JevantiqueTM if you have had your uterus removed (hysterectomy).

JevantiqueTM contains a progestin to decrease the chances of getting cancer of the uterus. If you do not have a uterus, you do not need a progestin and you should not take JevantiqueTM.

Do not start taking JevantiqueTM if you:

• currently have or have had certain cancers. Estrogens may increase the chances of getting certain types of cancers, including cancer of the breast and uterus. If you have or had cancer, talk with your healthcare provider about whether you should take JevantiqueTM.
• had a stroke or heart attack in the past year.
• currently have or have had blood clots.
• currently have or have had liver problems.
• are allergic to JevantiqueTM or any of its ingredients. See the end of this leaflet for a list of ingredients in JevantiqueTM.
• think you may be pregnant. If you think you may be pregnant, do not take JevantiqueTM.

Tell your healthcare provider:

• if you are breastfeeding. The hormones in JevantiqueTM can pass into your milk.

• about all of your medical problems. Your healthcare provider may need to check you more carefully if you have certain conditions, such as asthma (wheezing), epilepsy (seizures), migraine, endometriosis, lupus, problems with your heart, liver, thyroid, kidneys, or have high calcium levels in your blood.

• about all the medicines you take, including prescription and nonprescription medicines, vitamins, and herbal supplements. Some medicines may affect how JevantiqueTM works. JevantiqueTM may also affect how your other medicines work.

• if you are going to have surgery or will be on bed rest. You may need to stop taking estrogens and progestins.

How should I take JevantiqueTM?

Take your JevantiqueTM pill once a day at about the same time each day. If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and go back to your normal schedule. Do not take two doses at the same time.

Start at the lowest dose and talk to your healthcare provider about how well that dose is working for you.

Estrogens should only be used as long as needed. You and your healthcare provider should reevaluate every 3 to 6 months whether or not you still need treatment with JevantiqueTM.

What are the possible risks and side effects of JevantiqueTM?

Less common but serious side effects include:

• Breast cancer
• Cancer of the uterus
• Stroke
• Heart attack
• Blood clots
• Dementia
• Gallbladder disease
• Ovarian cancer

These are some of the warning signs of serious side effects:

• Breast lumps
• Unusual vaginal bleeding
• Dizziness and faintness
• Changes in speech
• Severe headaches
• Chest pain
• Shortness of breath
• Pains in your legs
• Changes in vision
• Vomiting

Call your healthcare provider right away if you get any of these warning signs, or any other unusual symptom that concerns you.

Common side effects include:

• Headache
• Breast pain
• Irregular vaginal bleeding or spotting
• Stomach/abdominal cramps, bloating
• Nausea and vomiting
• Hair loss

Other side effects include:

• High blood pressure
• Liver problems
• High blood sugar
• Fluid retention
• Enlargement of benign tumors of the uterus (“fibroids”)
• Vaginal yeast infection

These are not all the possible side effects of JevantiqueTM. For more information, ask your healthcare provider or pharmacist.

What can I do to lower my chances of a serious side effect with JevantiqueTM?

• Talk with your healthcare provider regularly (every 3-6 months) about whether you should continue taking JevantiqueTM.
• See your healthcare provider right away if you develop vaginal bleeding while taking JevantiqueTM.
• Have a breast exam and mammogram (breast x-ray) every year unless your healthcare provider tells you something else. If members of your family have had breast cancer or if you have ever had breast lumps or an abnormal mammogram (breast x-ray), you may need to have breast exams more often.
• If you have high blood pressure, high cholesterol (fat in the blood), diabetes, are overweight, or use tobacco, you may have higher chances for getting heart disease.  Ask your healthcare provider for ways of lowering your chances for getting heart disease.

General information about safe and effective use of JevantiqueTM

A number of studies have suggested that use of oral contraceptives decreases the risk of ovarian cancer. Specifically, the risk of epithelial ovarian cancers is decreased by 40%. The protection against ovarian cancer may last for 10 to 15 years after discontinuation of oral contraceptives. After long term use (12 years), the risk of ovarian cancer is decreased by as much as 80%.

The risk of endometrial cancer is decreased by approximately 50%. Protection may last for 15 years after discontinuation and may be greatest for nulliparous women who may be at higher risk for endometrial carcinoma than other women.

The incidence of hospitalization for pelvic inflammatory disease is approximately 50% lower in women taking oral contraceptives. The reason for the decrease in the frequency (or severity) of pelvic inflammatory disease in women taking oral contraceptives has not been fully elucidated.

Some recent studies have suggested that the decrease in frequency of functional ovarian cysts reported with some older formulations may not occur in women taking newer low dose formulations.

One recent study (The Nurses' Health Study) has suggested that long term use of oral contraceptives is safe and does not adversely affect long term risk for mortality.[Ref]

Women taking oral contraceptive combinations may have experienced several non-contraceptive health benefits. These benefits include protection against two malignant neoplasms (endometrial carcinoma and ovarian cancer). In addition, use of oral contraceptive combinations has reportedly decreased the frequency of benign breast tumors, decreased the risk of ovarian cysts, decreased the risk of ectopic pregnancy, increased menstrual regularity, decreased the incidence of iron deficiency anemia, decreased the incidence of dysmenorrhea, and decreased the incidence of pelvic inflammatory disease.[Ref]

Gastrointestinal

Gastrointestinal side effects have included nausea, which occurred in approximately 10% of treated women and was more frequent during the first cycles of therapy. Some early reports suggested an association between oral contraceptive use and gallbladder disease.[Ref]

Cases of oral contraceptive-induced esophageal ulceration and geographic tongue have been reported rarely.

More recent studies have suggested that the risk of gallbladder disease is minimal.[Ref]

Oncologic

Oncologic side effects have included reports of increased risk of invasive breast cancer. A large study (n = 16,608 postmenopausal women) of conjugated equine estrogens and medroxyprogesterone was terminated in 2002 due to the increased risk of coronary heart disease, stroke, and pulmonary embolism. A number of studies have examined a possible relationship between the use of oral contraceptives and the development of breast cancer. Many of the studies have reported conflicting results. A committee of the World Health Organization evaluated these studies and the risks of breast cancer and concluded that: "Numerous studies have found no overall association between oral contraceptive use and risk of breast cancer." In addition, the same committee also examined a possible relationship between oral contraceptive use and neoplasms of the uterine cervix and concluded that: "There are insufficient data to draw any firm conclusions regarding the effects of combined oral contraceptives on the risk of cervical adenocarcinoma."[Ref]

The World Health Organization committee also noted that some studies "have found a weak association between long-term use of oral contraceptives and breast cancer diagnosed before the age of 36, and perhaps up to the age 45....It is unclear whether this observed association is attributable to bias, the development of new cases of cancer, or accelerated growth of existing cancers."

The World Health Organization committee further concluded that there is no increased risk of breast cancer in women over the age of 45 who have previously taken oral contraceptives. In addition, studies suggest that use of oral contraceptives does not place specific groups of women (like those with a family history of breast cancer) at higher or lower risk, and variations in the hormonal content of oral contraceptives do not influence the risk of breast cancer.

In general, studies evaluating the potential risk of cervical cancer in patients taking oral contraceptives have been complicated by the large number of confounding factors which make investigations into the epidemiology of this neoplasm difficult. Some studies have suggested that women taking oral contraceptives are at increased risk of dysplasia, epidermoid carcinoma, and adenocarcinoma of the cervix. However, other studies have not found such an association.[Ref]

Cardiovascular

Detailed information concerning the effects of oral contraceptive therapy on lipid metabolism is available in the Endocrine paragraph of this side effect monograph.

Some early investigations of women taking high dose estrogen combinations (50 mcg or more of ethinyl estradiol or equivalent daily) suggested that such women may be at increased risk of cardiovascular complications (myocardial infarction, stroke, and vascular thrombosis, including venous thromboembolism). However, more recent large investigations of women taking low dose estrogen combinations have suggested that oral contraceptive use is not associated with an increased risk of serious cardiovascular complications in healthy non smoking women up to the age of 45. (For women aged 35 to 44 who smoke or who have preexisting systemic diseases that may affect the cardiovascular system, use of oral contraceptives is not recommended.)

However, some investigators have suggested that even the new low dose products may result in adverse effects on lipid metabolism and should prompt careful review of a woman's cardiovascular risk factors before a decision to use oral contraceptive combinations is made.

The frequency of both subarachnoid hemorrhage and thrombotic stroke has been reported by some investigators to be higher in women taking oral contraceptive hormones. However, other investigators have suggested that the risk of these effects for women using newer low dose formulations are very small for young women without underlying cardiovascular disease or other risk factors.[Ref]

Cardiovascular side effects have included reports of increased risk of coronary heart disease, stroke, and pulmonary embolism. A large study (n = 16,608 postmenopausal women) of conjugated equine estrogens and medroxyprogesterone was terminated in 2002 due to the increased risk of coronary heart disease, stroke, and pulmonary embolism. Earlier studies had suggested that unopposed estrogen therapy may decrease the risk of coronary heart disease by as much as 35% and that combination therapy with a progestin may also decrease coronary risk. Cardiovascular side effects of the estrogen component of this combination have also included reports of hypertension. However, significant blood pressure increases generally occur only in women receiving high-dose estrogen products (50 mcg or more of ethinyl estradiol or equivalent daily). Estrogens have also been associated with edema. In addition, exogenous estrogens may exert cardioprotective effects by causing favorable changes in lipid profiles. These beneficial effects, however, may be partially or completely offset by alterations in lipid profiles induced by exogenous progestins.[Ref]

Endocrine

Endocrine side effects have included reports of complex alterations in plasma lipid profiles and carbohydrate metabolism. In addition, oral contraceptive use has been reported to cause conception delay.[Ref]

All the progestins which occur in commercially available oral contraceptive combinations have adverse effects on lipid profiles. Specifically, these progestins exert antiestrogen and androgen effects and decrease HDL (and HDL2) cholesterol levels and increase LDL cholesterol levels. However, the estrogens in oral contraceptive combinations exert opposing effects. Consequently, alterations in lipid profiles are related to the relative amount and potency of the specific estrogen and progestin in a given product. (Norethindrone exerts a moderate androgen effect and weak progestin and antiestrogen effects.)

A number of investigations have suggested that oral contraceptive combinations may decrease glucose tolerance. However, some recent studies with low dose preparations have suggested that decreases in glucose tolerance due to oral contraceptive combinations are generally minimal.

Despite the potentially adverse effects of oral contraceptives on lipid levels and glucose tolerance, some investigators have suggested that young diabetic women without existing vascular disease or severe lipidemias may be candidates for low dose oral contraceptive combinations provided that they receive close monitoring for adverse metabolic effects.[Ref]

Hepatic

Hepatic side effects have included focal nodular hyperplasia, intrahepatic cholestasis, liver cell adenomas, hepatic granulomas, hepatic hemangiomas and well-differentiated hepatocellular carcinomas, which have been reported rarely in association with estrogen therapy and therapy with oral contraceptive combinations.[Ref]

The rate of death due to hepatocellular carcinoma in the United States has not changed during the last 25 years (a time during which use of oral contraceptive hormones has increased dramatically).

A committee of the World Health Organization has reported that in developing countries where hepatitis B virus infection and hepatocellular carcinoma are common, "short term use of oral contraceptives does not appear to be associated with an increased risk. Data on the effects of long term use are scarce."

A recent Italian case-control study of women with hepatocellular carcinoma has suggested that the relative risk of hepatocellular carcinoma is 2.2 for oral contraceptive users compared to women who never used oral contraceptives.

A similar American case-control study from 1989 also reported a strong association between oral contraceptive use and hepatocellular carcinoma but concluded that: "If this observed association is causal, the actual number of cases of liver cancer in the United States attributable to oral contraceptive use is small. Therefore, these findings do not have public health importance in the United States and other Western nations."[Ref]

Hematologic

Cases of venous thrombosis, pulmonary embolism (sometimes fatal), and arterial thrombosis have been reported rarely.

Previous thrombotic disease is considered a contraindication to use of oral contraceptive combinations.[Ref]

Hematologic side effects have included the risk of thromboembolism that is associated with the use of exogenous estrogens. However, because the dose of exogenous estrogens is low in most commercially available preparations, the risk of thromboembolism is minimal for most women (except women who are over age 35 and smoke and women with a history of previous thrombotic diseases).[Ref]

Genitourinary

Genitourinary side effects have commonly included breakthrough bleeding and spotting, especially during the first several cycles of oral contraceptive use. Non-hormonal causes of such bleeding should be excluded. Additional side effects reported with estrogen and/or progestin therapy include changes in vaginal bleeding pattern and abnormal withdrawal bleeding or flow, increase in size of uterine leiomyomata, vaginal candidiasis, change in amount of cervical secretion, change in cervical ectropion, ovarian cancer, endometrial hyperplasia, endometrial cancer and vaginitis.[Ref]

Some women experience oligomenorrhea and amenorrhea following termination or oral contraceptive use.[Ref]

Psychiatric

Psychiatric side effects have included depression and precipitation of panic disorder.[Ref]

Immunologic

Immunologic side effects have included rare cases of oral contraceptive-induced systemic lupus erythematosus.[Ref]

Nervous system

Nervous system side effects have included chorea, which has been reported once in association with oral contraceptives.[Ref]

Ocular

Ocular side effects have included rare cases of retinal thrombosis. In addition, the manufacturers of oral contraceptive products report that some patients develop changes in contact lens tolerance.[Ref]

Respiratory

Respiratory side effects have included reports of increased risk of pulmonary embolism. A large study (n = 16,608 postmenopausal women) of conjugated equine estrogens and medroxyprogesterone was terminated in 2002 due to the increased risk of coronary heart disease, stroke, and pulmonary embolism.[Ref]

A case of fatal pulmonary venooclusive disease has been associated with oral contraceptive therapy.[Ref]
