DRUG INTERACTIONS: Tell your doctor of all prescription and nonprescription medication you may use, especially: methadone. Tell your doctor if you take any drugs that cause drowsiness such as: medicine for sleep, sedatives, tranquilizers, anti- anxiety drugs (e.g., diazepam, lorazepam), narcotic pain relievers (e.g., codeine, morphine), psychiatric medicines (e.g., phenothiazines such as chlorpromazine or tricyclic antidepressants such as amitriptyline), anti-seizure drugs (e.g., carbamazepine, topiramate), muscle relaxants, certain antihistamines (e.g., diphenhydramine). Acetaminophen is an ingredient in many nonprescription products and in some combination prescription medications. Read the labels carefully before taking other pain relievers, fever reducers or cold products to see if they also contain acetaminophen. Consult your pharmacist if you are uncertain if your other prescription or nonprescription products contain acetaminophen. (Also see adult maximum daily dose information in Side Effects section).
