Medications for a Brain Tumor

Brain tumors often cause symptoms. Also, your treatment is likely to produce some side effects. To help you feel better, your doctor may prescribe medications. Ask your doctor or pharmacist about possible interaction with other medications.


Steroids reduce brain swelling. Always take them as directed. Do not stop taking them without your doctor’s approval.

Side effects can include water retention, weight gain, hair growth, insomnia, stomach ulcers, increased risk of infection, and mood changes.


Anticonvulsants help prevent seizures or convulsions. Always take them as directed. You will have blood tests to make sure you get the right dosage.

Call the doctor right away if you have any of these side effects: trouble breathing, rash, balance problems, or dizziness.

Other Medications

You may also need other medications to manage symptoms and side effects:

  • Antiemetics to control nausea
  • Antacids to control stomach acid
  • Laxatives or stool softeners to treat constipation
  • Medications to control pain
  • Hormones to replace the ones that your body isn’t producing or to treat certain types of tumors
