Before taking phentermine, tell your doctor about all of your medical conditions. Especially tell your doctor if you:

• are allergic to phentermine or to any of its ingredients
• have high blood pressure
• drink alcohol
• a history of drug abuse or dependence

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Phentermine falls into category X. Phentermine should not be used during pregnancy because weight loss offers no potential benefit to a pregnant woman and may result in fetal harm. There are no situations where the benefits of the medication for the mother outweigh the risks of harm to the baby. These medicines should never be used by pregnant women.

Tell your doctor if you are breastfeeding or plan to breastfeed.

It is not known if phentermine crosses into human milk. Because many medications can cross into human milk and because of the possibility for serious adverse reactions in nursing infants with use of this medication, a choice should be made whether to stop nursing or stop the use of this medication. Your doctor and you will decide if the benefits outweigh the risk of using phentermine.

• Store phentermine at 20° to 25°C (68° to 77°F).
• Keep this and all medicines out of the reach of children.

Do not use phentermine if you have taken an MAO inhibitor in the past 14 days. A dangerous drug interaction could occur. MAO inhibitors include isocarboxazid, linezolid, phenelzine, rasagiline, selegiline, and tranylcypromine.

You should not take phentermine if you are allergic to it, or if you have:

• a history of heart disease (coronary artery disease, heart rhythm problems, congestive heart failure, stroke);

• a history of pulmonary hypertension;

• severe or uncontrolled high blood pressure;

• overactive thyroid;

• glaucoma;

• if you are pregnant or breast-feeding;

• if you are in an agitated state;

• if you have a history of drug or alcohol abuse; or

• if you are allergic to other diet pills, amphetamines, stimulants, or cold medications.

Taking phentermine together with other diet medications such as fenfluramine (Phen-Fen) or dexfenfluramine (Redux) can cause a rare fatal lung disorder called pulmonary hypertension. Do not take phentermine with any other diet medications without your doctor's advice.

To make sure you phentermine is safe for you, tell your doctor if you have:

• high blood pressure;

• diabetes;

• kidney disease;

• a thyroid disorder; or

• if you are allergic to aspirin or to yellow food dye (FD & C Yellow No. 5, or tartrazine).

Phentermine may be habit forming. Never share phentermine with another person, especially someone with a history of drug abuse or addiction. Keep the medication in a place where others cannot get to it.

FDA pregnancy category X. Weight loss during pregnancy can harm an unborn baby, even if you are overweight. Do not use phentermine if you are pregnant.

Phentermine can pass into breast milk and may harm a nursing baby. You should not breast-feed while taking phentermine.

Do not give this medication to a child younger than 16 years old.

Drinking alcohol can increase certain side effects of phentermine.
