Drug Interaction Report

Felbamate may increase the blood levels and effects of thiotepa. You may have increased side effects such as nausea, vomiting, mouth ulcers, skin conditions, and low blood cell counts, which can make you more likely to develop anemia, bleeding problems, and infections. Your doctor may already be aware of the risks but has determined that this is the best course of treatment for you and has taken appropriate precautions and is monitoring you more closely. Contact your doctor if you experience potential signs and symptoms of these conditions such as paleness of skin, fatigue, dizziness, fainting, unusual bleeding or bruising, fever, chills, sore throat, body aches, or other flu-like symptoms. You may need a dose adjustment or additional monitoring by your doctor to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Alcohol can increase the nervous system side effects of felbamate such as dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment. You should avoid or limit the use of alcohol while being treated with felbamate. Do not use more than the recommended dose of felbamate, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. Talk to your doctor or pharmacist if you have any questions or concerns.
