Medication Management Before Brain Cancer Treatment
This is an important question, and the answer depends on which specific medications you're taking and what type of treatment you're about to receive. Let me explain what you need to know.
General Pre-Treatment Medication Guidelines
According to the Musella Foundation's Brain Tumor Guide for the Newly Diagnosed, you should:
BEFORE SURGERY specifically:
- Stop aspirin and ibuprofen at least one week before surgery (if you have time)
- Discontinue herbs and supplements at least one week before surgery
- These medications slow your platelets (blood cells that help clotting), which can increase bleeding during surgery and slow wound healing after
IMPORTANT: Always inform your medical team about ALL medications you're taking, including:
- Prescription drugs
- Over-the-counter medications
- Vitamins and supplements
- Herbal products
Special Consideration: Anti-Seizure Medications
According to NCCN Guidelines for Central Nervous System Cancers, there's a critical issue with certain anti-seizure medications if you're prescribed them:
Avoid older anti-seizure drugs like:
- Phenytoin (Dilantin)
- Phenobarbital
- Carbamazepine
Why? These medications interfere with how your body processes chemotherapy drugs, making treatments less effective. Instead, doctors typically recommend newer options like:
- Levetiracetam (Keppra)
- Topiramate (Topamax)
- Valproic acid
- Lacosamide
What You Should Do RIGHT NOW
Before your treatment begins, ask your healthcare team:
- "Which of my current medications should I stop before treatment, and when should I stop them?"
- "Are any of my medications going to interact with my cancer treatment?"
- "Should I fill all my prescriptions at the same pharmacy to prevent drug interactions?" (The Musella Foundation recommends this for safety)
- "Do I need to adjust any medications during or after treatment?"
- "What should I do if I'm currently on an older anti-seizure medication—should we switch to a newer one?"
Keep a Complete Medication List
The Musella Foundation emphasizes that you should:
- Maintain an accurate, ongoing record of all medications with dosages
- Note the names of physicians who prescribed each one
- Have your medical team review this complete list before they prescribe anything new
- Update it regularly as treatments change
Why This Matters for Brain Cancer Specifically
Brain cancer treatment often involves multiple therapies working together (surgery, radiation, chemotherapy, immunotherapy). Each medication can interact with others, so your care team needs the complete picture to keep you safe and maximize treatment effectiveness.
