What should I avoid?
Do not drink alcohol. Dangerous side effects or death can occur when alcohol is combined with methadone. Check your food and medicine labels to be sure these products do not contain alcohol.
Methadone may impair your thinking or reactions. Avoid driving or operating machinery until you know how this medicine will affect you. Dizziness or severe drowsiness can cause falls or other accidents.
Grapefruit and grapefruit juice may interact with methadone and lead to unwanted side effects. Discuss the use of grapefruit products with your doctor.
