I currently take four 500mg tablets of metformin a day for diabetes. I recently sprained my back. Can I take Excedrin Back & Body? Can I use the therma patch for my back pain?

From Ask the Pharmacist 

There are no direct drug interactions between metformin (Glucophage) and Excedrin Back & Body (acetaminophen with aspirin). Take the metformin as instructed, usually around meal times. Limit the Excedrin to keep the daily intake of acetaminophen to 4000mg or less. The aspirin may irritate the stomach, so take this with food or milk.

People with diabetes sometimes have issues with circulation, generally to the extremities or peripheral areas. If your circulation is good, you may try the Therma Patch but watch for local irritation and skin problems. Only use on intact skin.
