Common questions about Erleada (apalutamide)

No, Erleada (apalutamide) doesn’t cure cancer. Instead, it helps control prostate cancer by blocking testosterone, which the cancer needs to grow. This can slow down the cancer and keep it from spreading, but the medication doesn’t completely get rid of it.

No, Erleada (apalutamide) isn’t chemotherapy. Chemotherapy works by directly killing fast-growing cells, including cancer cells. Erleada (apalutamide) is a type of hormone therapy called an androgen receptor inhibitor, which blocks testosterone from helping prostate cancer grow and spread.

You usually take Erleada (apalutamide) every day for as long as it keeps your prostate cancer under control. In studies, some people took the medication for several years. There isn’t a set time limit, since treatment depends on how well it works for you and whether side effects become too hard to manage. Your oncologist will check your progress regularly and decide if you should keep taking it.

Hair loss isn’t a common side effect of Erleada (apalutamide). If you do notice changes in your hair while taking this medication, let your oncologist know.

It usually takes about 2 weeks for most of Erleada (apalutamide) to leave your body after a single dose. This time frame is based on the medication's half-life. The half-life is how long it takes for half the medication to leave your body. If you have more questions about how long Erleada (apalutamide) stays in your system, ask your oncologist.

Erleada (apalutamide) can start to work within the first few months of treatment. For some people, it might take a little longer. Your oncologist will check your blood tests and scans over time to see how well it’s working for you.
