Women who are pregnant must not use thalidomide. Women must avoid becoming pregnant while taking this medication. Even a single dose of thalidomide has caused severe (often fatal) birth defects when used during pregnancy. You must have 2 negative pregnancy tests before you start treatment with thalidomide (within 10 to 14 days before and 24 hours before starting), repeating the test at least monthly. Do not start or continue thalidomide treatment unless you have a negative pregnancy test result.

Female patients must use 2 effective forms of birth control (or completely avoid sexual intercourse) for 1 month before starting thalidomide, during use, and for 1 month after stopping this drug. Talk to your doctor about reliable birth control choices. If your period is late, or if you have sexual intercourse at any time without using 2 effective forms of birth control, stop taking this medication and contact your doctor right away. (See also Precautions section.)

Because thalidomide also passes into semen, men who use this drug and have sex with women must use a latex condom during all sexual contact, even if they have had a vasectomy. Keep using condoms and other birth control as directed until 1 month after thalidomide treatment has been stopped.

To receive thalidomide in the United States, you must understand, agree to, and carefully follow the requirements of the REMS Program for this medication. If you live in Canada or any other country, consult your doctor and pharmacist for your country's regulations.

When used to treat a certain type of cancer (multiple myeloma), thalidomide can increase the risk of serious problems from blood clots (such as heart attack, stroke, blood clots in the lungs or legs). Get medical help right away if you develop shortness of breath/rapid breathing, chest/jaw/left arm pain, weakness on one side of the body, trouble speaking, sudden vision changes, unusual sweating, confusion, sudden dizziness/fainting, pain/swelling/warmth in the groin/calf, or sudden/severe headaches. While you are taking thalidomide, your doctor may also direct you to take aspirin or other "blood thinners" (such as warfarin) to lessen the risk of these types of blood clots. Talk to your doctor for more information, and tell him/her if you have diabetes, high blood pressure or high cholesterol, kidney problems, or if you smoke. (See also Side Effects section.)

This medication is used to treat or prevent certain skin conditions related to Hansen's disease, once known as leprosy (erythema nodosum leprosum). Thalidomide is also used to treat a certain type of cancer (multiple myeloma). It works in Hansen's disease by reducing swelling and redness (inflammation). It also reduces the formation of blood vessels that feed tumors.

Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day. If you are taking this medication for Hansen's disease, your skin condition may become worse when the drug is suddenly stopped. Your dose may need to be gradually decreased.

Tell your doctor if your condition does not get better or if it gets worse after 2 weeks.

Thalidomide must not be used during pregnancy due to the risk of severe birth defects and other serious, sometimes fatal harm to an unborn baby. If you are female and become pregnant or think you may be pregnant, if your period is late or you have unusual menstrual bleeding, or if you stop using 2 forms of birth control, stop taking thalidomide and tell your doctor right away.

It is very important for women to use 2 forms of effective birth control while taking this medication. Some drugs may cause hormonal birth control (such as pills, patch, ring) to work less well by decreasing the amount of birth control hormones in your body. This effect can result in pregnancy. Examples include griseofulvin, modafinil, rifamycins (such as rifampin, rifabutin), ritonavir, St. John's wort, drugs used to treat seizures (such as barbiturates, carbamazepine, felbamate, phenytoin, primidone, topiramate), HIV drugs (such as nelfinavir, nevirapine), among others.

Tell your doctor when you start any new drug, and discuss if you should use reliable backup birth control while using the new drug and for 1 month after stopping the new drug.
