Ingredients. Common ingredients in Excedrin are aspirin (acetylsalicylic acid), acetaminophen (paracetamol), and caffeine. Excedrin Tension Headache is a little different because it does not contain aspirin. Each geltab (or coated tablet or gelcap) contains 500 mg of acetaminophen (paracetamol) and 65mg of caffeine.
Excedrin Migraine. One ingredient in this product is acetaminophen. Taking too much acetaminophen may cause serious (possibly fatal) liver disease. Adults should not take more than 4000 milligrams (4 grams) of acetaminophen a day.
