Your healthcare professionals (e.g., doctor or pharmacist) may already be aware of any possible drug interactions and may be monitoring you for it. Do not start, stop or change the dosage of any medicine before checking with them first.
This drug should not be used with the following medications because very serious (possibly fatal) interactions may occur: MAO inhibitors (e.g., furazolidone, isocarboxazid, linezolid, moclobemide, phenelzine, procarbazine, rasagiline, selegiline, tranylcypromine).
Avoid taking MAO inhibitors within 2 weeks before, during, and after treatment with tramadol/acetaminophen.
If you are currently using any of these medications listed above, tell your doctor or pharmacist before starting tramadol/acetaminophen.
Before using this medication, tell your doctor or pharmacist of all prescription and nonprescription/herbal products you may use, especially of: carbamazepine, SNRI antidepressants (e.g., venlafaxine, duloxetine), SSRI antidepressants (e.g., fluoxetine, paroxetine), sibutramine, other narcotic medications, warfarin.
Also report the use of drugs that might increase seizure risk when combined with tramadol such as isoniazid (INH), phenothiazines (e.g., thioridazine, chlorpromazine, promethazine), theophylline, or tricyclic antidepressants (e.g., amitriptyline), among others. Consult your doctor or pharmacist for details.
Tell your doctor or pharmacist if you also take drugs that cause drowsiness such as certain antihistamines (e.g., diphenhydramine), anti-anxiety drugs (e.g., diazepam), anti-seizure drugs (e.g., phenytoin), medicine for sleep (e.g., zolpidem), muscle relaxants (e.g., cyclobenzaprine).
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 whether your other prescription or nonprescription products contain acetaminophen. (See also Side Effects section.) Check the labels on all your medicines (e.g., cough-and-cold products) because they may contain drowsiness-causing ingredients. Ask your pharmacist about the safe use of these products.
