Drug interactions between methadone and oxcarbazepine
Interactions between your drugs
Applies to: methadone and oxcarbazepine
OXcarbazepine may reduce the blood levels of methadone, which may make the medication less effective in treating your condition. Additionally, if you have been receiving treatment with methadone, adding OXcarbazepine may cause you to experience unpleasant withdrawal symptoms such as watery eyes, runny nose, sneezing, yawning, excessive sweating, goose bumps, fever, chills, flushing, restlessness, irritability, anxiety, depression, pupil dilation, tremor, rapid heart beat, body aches, involuntary twitching and kicking, abdominal cramping, loss of appetite, nausea, vomiting, diarrhea, and weight loss. On the other hand, if you have been receiving both medications, discontinuing OXcarbazepine may increase the blood levels of methadone, which could lead to an overdose. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring 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 OXcarbazepine such as dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment.
