What should I avoid while taking Xtandi?

While taking Xtandi (enzalutamide), a prescription medication used to treat metastatic castration-resistant prostate cancer, you should avoid having unprotected sex with a woman who could become pregnant or is pregnant. Xtandi can be harmful to a developing fetus, so it is important that if you have sex with a woman who could become pregnant, you use a condom plus another birth control method. Do this for three months after you stop taking Xtandi. If you have sex with a pregnant woman, use a condom while you're on Xtandi and for three months after you stop taking it.

One side effect of taking Xtandi is having seizures. While you're taking this drug, you should avoid participating in activities where a sudden loss of consciousness could result in serious harm to yourself or others.
