For Women: If you have not had a hysterectomy or have not been in menopause for at least 24 months in a row, you will be required to use two forms of birth control beginning 4 weeks before you start taking lenalidomide and ending 4 weeks after you stop taking it. Even women with fertility problems are required to use birth control while taking this medication. 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 lenalidomide, you will have a pregnancy test every 4 weeks.
The birth control method you use 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 latex condom, a diaphragm, or a cervical cap.
Stop using lenalidomide 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.
For Men: You must not cause a woman to become pregnant while you are taking lenalidomide because the medicine may affect your sperm and cause birth defects in the baby. You must agree in writing to always use latex condoms when having sex with a woman who is able to get pregnant, even if you have had a vasectomy. Contact your doctor if you have had unprotected sex, even once, or if you think your female sexual partner may be pregnant.
