Bicalutamide: What You Need to Know

If you or a loved one has been prescribed bicalutamide, you probably have a lot of questions. It’s a medication most often used in prostate cancer treatment, either on its own or together with other hormonal therapies. Below you’ll find the basics – how it works, when doctors use it, how to take it safely, and what side effects to watch for.

How Bicalutamide Works and When It’s Used

Bicalutamide belongs to a class of drugs called anti‑androgens. Prostate cancer cells grow when they’re exposed to male hormones (androgens) like testosterone. The drug blocks the hormone’s ability to bind to its receptors, slowing down tumor growth. Doctors usually give bicalutamide to men whose cancer has spread beyond the prostate or to those who are getting radiation therapy. It can also be part of a combination called “combined androgen blockade,” where it’s paired with a drug that lowers testosterone levels.

Because it targets hormone pathways, bicalutamide isn’t a cure, but it can keep the disease in check for years. The decision to start the medicine depends on cancer stage, PSA levels, overall health, and how the patient tolerates other hormone treatments.

Dosage, Side Effects, and Safety Tips

The typical adult dose is a 50 mg tablet taken once daily, with or without food. Your doctor may adjust the amount based on blood tests and how you feel. It’s important to take the same dose every day – skipping days can reduce effectiveness.

Most people notice a few mild side effects at first. The most common are:

• Hot flashes or night sweats
• Breast tenderness or enlargement
• Stomach upset, nausea, or loss of appetite
• Weakness or fatigue

These usually improve after a few weeks. If you get severe pain, yellowing of the skin or eyes, or sudden vision changes, call your doctor right away – they could signal liver problems or other serious issues.

Because bicalutamide interferes with hormone signaling, it can affect other medicines. Anticoagulants (like warfarin), certain anti‑seizure drugs, and some cholesterol‑lowering meds may need dose tweaks. Always share a full medication list with your healthcare team.

Regular monitoring helps catch problems early. Expect blood tests for liver function and PSA every 3–6 months. If your testosterone level drops too low, your doctor might pause or change the treatment.

Here are a few practical tips to make the experience smoother:

• Take the pill at the same time each day – set a phone reminder if you need to.
• Stay hydrated and eat a balanced diet to reduce stomach upset.
• Report any new or worsening symptoms, even if they seem unrelated.
• Ask about bone health; long‑term hormone therapy can weaken bones, so calcium and vitamin D supplements might be recommended.

Remember, bicalutamide is just one piece of the prostate cancer puzzle. It works best when combined with regular doctor visits, healthy lifestyle choices, and open communication with your care team.
