flutamide
Summary
Flutamide is used to treat prostate cancer, which is a type of cancer that occurs in the prostate gland in men. It helps slow or stop the growth of cancer cells by blocking male hormones.
Flutamide works by blocking the effects of androgens, which are male hormones that can promote the growth of prostate cancer cells. This action helps slow or stop the growth of the cancer.
The usual dose of Flutamide for adults is 250 mg taken three times a day. It is taken orally, which means by mouth, and can be taken with or without food.
Common side effects of Flutamide include hot flashes, which are sudden feelings of warmth, diarrhea, and nausea, which is a feeling of sickness in the stomach.
Flutamide can cause liver damage, so regular liver function tests are necessary. It should not be used by people with severe liver disease, which is a condition where the liver is not functioning properly.
