What is apalutamide?
Apalutamide is an anti-androgen. It works in the body by preventing the actions of androgens (male hormones).
Apalutamide is used to treat prostate cancer that has spread to other parts of the body (metastatic) and is also being treated with another medicine or with surgery.
Apalutamide is also used to treat prostate cancer that has not spread to other parts of the body, after surgery or other cancer treatments did not work or have stopped working.
Apalutamide is used together with a gonadotropin-releasing hormone (GnRH) or with surgical castration (removal of the testicles).
Although apalutamide is not for use by women, this medicine can cause birth defects if a woman is exposed to it during pregnancy.
Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.
