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.
