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 LHRH agonists, to enhance its effectiveness. This medication is typically taken orally in tablet form and is usually well-tolerated. Common side effects may include hot flashes, fatigue, and gastrointestinal issues. Patients should follow their healthcare provider's instructions and report any unusual symptoms during treatment.
