Before taking Thalomid

You should not use Thalomid if you are allergic to thalidomide.

Thalidomide can cause severe, life-threatening birth defects or death of a baby if the mother or the father is taking this medicine at the time of conception or during pregnancy. Even one dose of thalidomide can cause major birth defects of the baby's arms and legs, bones, ears, eyes, face, and heart. Never use thalidomide if you are pregnant. Tell your doctor right away if your period is late while taking Thalomid.

For Women: If you have not had a hysterectomy, you will be required to use two reliable forms of birth control beginning 4 weeks before you start taking Thalomid and ending 4 weeks after you stop taking it. Even women with fertility problems are required to use birth control while taking Thalomid. You must also have a negative pregnancy test at 10 to 14 days before treatment and again at 24 hours before. While you are taking this medicine, you will have a pregnancy test every 2 to 4 weeks.

Your birth control method must be proven highly effective, such as birth control pills, an intrauterine device (IUD), a tubal ligation, or a sexual partner's vasectomy. The extra form of birth control you use must be a barrier method such as a condom, a diaphragm, a cervical cap, or contraceptive sponge.

Stop using Thalomid and call your doctor at once if you quit using birth control, if your period is late, or if you think you might be pregnant. Not having sexual intercourse (abstinence) is the most effective method of preventing pregnancy.

For Men: Use a condom to prevent pregnancy during your treatment, and for up to 4 weeks after you stop taking it. You must always use latex condoms when having sex with a woman who is able to get pregnant, even if you have had a vasectomy. Call your doctor if you have had unprotected sex, even once, or if you think your female sexual partner may be pregnant.

Treatment with Thalomid may increase your risk of a blood clot or stroke during treatment for multiple myeloma. Ask your doctor about your specific risk.

To make sure Thalomid is safe for you, tell your doctor if you have ever had:

heart disease, a stroke, or a blood clot;

a seizure;

if you need surgery; or

if you also use pembrolizumab (Keytruda).

You should not breastfeed while using thalidomide.
