Bicalutamide is a medication primarily used to treat prostate cancer. It belongs to a class of drugs known as anti-androgens, which work by blocking the action of male hormones like testosterone that can promote the growth of cancer cells. Bicalutamide is often prescribed in combination with other treatments, such as luteinizing hormone-releasing hormone (LHRH) agonists, to enhance its effectiveness. The drug is typically taken orally in tablet form and is usually well-tolerated, though it may cause side effects such as hot flashes, fatigue, and gastrointestinal issues. Regular monitoring by a healthcare provider is essential to manage any potential adverse effects and to assess the treatment's effectiveness.
