What is Xatmep (methotrexate)?
Methotrexate interferes with the growth of certain cells of the body, especially cells that reproduce quickly, such as cancer cells, bone marrow cells, and skin cells.
Methotrexate is used to treat certain types of cancer of the breast, skin, head and neck, or lung. Methotrexate is also used to treat severe psoriasis and rheumatoid arthritis.
Methotrexate is usually given after other medications have been tried without successful treatment of symptoms.
Methotrexate may also be used for purposes not listed in this medication guide.
What is the most important information I should know about Xatmep (methotrexate)?
Methotrexate is usually not taken every day. You must use the correct dose of methotrexate for your condition. Some people have died after taking methotrexate every day by accident.
Do not use methotrexate if you are pregnant or breast-feeding a baby.
Do not use methotrexate to treat psoriasis or rheumatoid arthritis if you have liver disease (especially if caused by alcoholism), or a blood cell or bone marrow disorder.
Call your doctor if you have unusual bruising or bleeding, or signs of infection (fever, chills, body aches).
Methotrexate can cause serious or life-threatening side effects on your liver, lungs, or kidneys. Tell your doctor if you have upper stomach pain, loss of appetite, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes), dry cough, shortness of breath, blood in your urine, or little or no urinating.
What should I discuss with my healthcare provider before taking Xatmep (methotrexate)?
You should not use this medicine if you are allergic to methotrexate. Do not use methotrexate to treat psoriasis or rheumatoid arthritis if you have:
alcoholism, cirrhosis, or other liver disease;
a blood cell disorder such as anemia (lack of red blood cells) or leukopenia (lack of white blood cells);
a bone marrow disorder; or
if you are breast-feeding a baby.
Methotrexate is sometimes used to treat cancer even when patients do have one of the conditions listed above. Your doctor will decide if this treatment is right for you.
To make sure methotrexate is safe for you, tell your doctor if you have:
a folate deficiency;
pneumonia or lung disease;
any type of infection; or
if you are receiving radiation treatments.
Methotrexate can cause birth defects in an unborn baby. Do not use methotrexate to treat psoriasis or rheumatoid arthritis if you are pregnant. Tell your doctor right away if you become pregnant during treatment.
You may need to have a negative pregnancy test before starting this treatment.
Use birth control to prevent pregnancy while you are using methotrexate, whether you are a man or a woman. Methotrexate use by either parent may cause birth defects.
If you are a man, use a condom to keep from causing a pregnancy while you are using methotrexate. Continue using condoms for at least 3 months after your last dose.
If you are a woman, use an effective form of birth control while you are taking methotrexate, and for 6 months after your last dose.
This medicine may affect fertility (your ability to have children), whether you are a man or a woman.
Methotrexate can pass into breast milk and may harm a nursing baby. You should not breast-feed while using this medicine.
Do not give this medicine to a child without the advice of a doctor.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An overdose of methotrexate can be fatal.

Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of methotrexate for the treatment of cancer (including acute lymphoblastic leukemia) and juvenile idiopathic arthritis in children. However, safety and efficacy have not been established in children with psoriasis.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of methotrexate in the elderly. However, elderly patients are more likely to have kidney problems, which may require caution and an adjustment in the dose.
Studies in women breastfeeding have demonstrated harmful infant effects. An alternative to this medication should be prescribed or you should stop breastfeeding while using this medicine.

Review Date: October 4, 2017
Polyarticular Juvenile Idiopathic Arthritis
Clinical trials in patients with polyarticular juvenile idiopathic arthritis were performed using other formulations of methotrexate.
In a 6-month, double-blind, placebo-controlled trial of 127 pediatric patients with juvenile idiopathic arthritis (JIA) (mean age, 10.1 years; age range 2.5 to 18 years, mean duration of disease, 5.1 years) on background non-steroidal anti-inflammatory drugs (NSAIDs) and/or prednisone, methotrexate given one time weekly at an oral dose of 10 mg/m2 provided significant clinical improvement compared to placebo as measured by either the physician’s global assessment, or by a patient composite (25% reduction in the articular-severity score plus improvement in parent and physician global assessments of disease activity). Over two-thirds of the patients in this trial had polyarticular-course JIA, and the numerically greatest response was seen in this subgroup treated with 10 mg/m2/week methotrexate. The overwhelming majority of the remaining patients had systemic-course JIA. All patients were unresponsive to NSAIDs; approximately one-third were using low dose corticosteroids. Weekly methotrexate at a dose of 5 mg/m2 was not significantly more effective than placebo in this trial.
Patient Counseling Information
Importance of Proper Dosing and Administration
Advise patient that the recommended dose should be taken one time weekly, as directed, and that mistaken daily use of the recommended dose has led to fatal toxicity [see Dosage and Administration (2.1), Warnings and Precautions (5.5)].
Advise patients and caregivers to measure Xatmep with an accurate milliliter measuring device. A household teaspoon is not an accurate measuring device. Advise patients and caregivers to ask their pharmacist to recommend an appropriate measuring device and for instructions for measuring the correct dose.
Bone Marrow Suppression and Serious Infections
Advise patient to contact their healthcare provider for new onset fever, symptoms of infection, easy bruising or persistent bleeding [see Warnings and Precautions (5.1, 5.2)].
Advise patients that methotrexate can cause renal toxicity [see Warnings and Precautions (5.3)].
Advise patients to contact their healthcare provider if they develop diarrhea, vomiting, or stomatitis [see Warnings and Precautions (5.4)].
Advise patients concerning the risk of hepatic toxicity and avoidance of alcohol during methotrexate treatment [see Warnings and Precautions (5.5)].
Advise patients to contact their healthcare provider for symptoms of cough, fever, and dyspnea [see Warnings and Precautions (5.6)].
Advise patients concerning the risk for severe hypersensitivity reactions due to Xatmep treatment. These can be fatal and may include severe dermatologic reactions such as toxic epidermal necrolysis, Stevens-Johnson syndrome, exfoliative dermatitis, and erythema multiforme. Advise patients to contact their healthcare provider for signs of a new or worsening rash [see Warnings and Precautions (5.7)].
Advise patients that there is a risk of secondary malignancies during or following treatment with Xatmep [see Warnings and Precautions (5.8)].
Advise females of reproductive potential of the potential risk to a fetus and to inform their healthcare provider of a known or suspected pregnancy [see Boxed Warning, Contraindications (4), Warnings and Precautions (5.9), Use in Specific Populations (8.1)].
Advise females of reproductive potential to use effective contraception during Xatmep therapy and for 6 months after the final dose [see Use in Specific Populations (8.3)].
Advise males of reproductive potential to use effective contraception during Xatmep therapy and for 3 months after the final dose [see Use in Specific Populations (8.3)].
Ineffective Immunization and Risks Associated with Live Vaccines
Advise patients to avoid receiving vaccines during treatment with Xatmep because they may not be effective and live virus vaccines may cause infection [see Warnings and Precautions (5.10)].
Advise patients of reproductive potential that Xatmep may cause impairment of fertility, oligospermia, and menstrual dysfunction [see Warnings and Precautions (5.11), Use in Specific Populations (8.3)].
Advise females not to breastfeed during therapy with Xatmep [see Use in Specific Populations (8.2)].
Proper Storage and Disposal
