Medications and Prostate Cancer Treatment: What You Need to Know

This is an important question, and the answer depends on which specific treatment you're planning to receive and which medications you're currently taking. Let me walk you through the key considerations.

General Principles

According to the CancerPatientLab webinars on prostate cancer treatment, there are several medication-related considerations before starting therapy:

Dental Work & Oral Health (Critical)

Before starting androgen deprivation therapy (ADT) — hormone-blocking drugs like Lupron, abiraterone, enzalutamide, or darolutamide — you should:

  • Complete any needed dental work
  • Establish excellent oral hygiene

This is important because ADT can affect bone health and dental complications can become more serious during treatment.

5-Alpha Reductase Inhibitors

If you're considering testosterone-based therapies (like bipolar androgen therapy), research shows that 5-alpha reductase inhibitors (medications that block conversion of testosterone to DHT) are typically used alongside testosterone treatment to manage side effects.

Bone Health Medications

The webinars emphasize that before or early in ADT, you should:

  • Start bone-protective medications (like denosumab/Xgeva)
  • Consider your bone density status

Cardiovascular Medications

This is particularly important: ADT can have cardiac side effects, so your care team may recommend:

  • Statins (cholesterol-lowering drugs)
  • Blood pressure medications
  • Possibly PCSK9 inhibitors or low-dose colchicine for cardiovascular protection

What You Should NOT Do Without Your Doctor

Do NOT stop any current medications on your own — especially:

  • Blood pressure medications
  • Heart medications
  • Diabetes medications
  • Blood thinners

Specific Questions to Ask Your Oncology Team

Before starting any prostate cancer treatment, ask your doctor:

  1. "Do I need to stop or adjust any of my current medications before starting treatment?"

  2. "Are there any drug interactions between my current medications and my cancer treatment?"

  3. "Should I start any preventive medications (bone protection, heart protection) before beginning hormone therapy?"

  4. "Do I need to complete any dental work before starting treatment?"

  5. "Will my treatment affect how my other medications work, or vice versa?"

The Bottom Line

According to the CancerPatientLab webinars, your oncology team should review ALL your medications — including over-the-counter drugs and supplements — before treatment begins. This is part of comprehensive treatment planning that considers your whole health picture, not just the cancer.

Your oncologist and pharmacist are your best resources for this decision. They have your complete medical history and can identify potential problems specific to YOUR situation.
