This combination medication is used to relieve tension and migraine headaches. Headache pain can sometimes be caused by widened blood vessels in the head. Isometheptene works by narrowing these widened blood vessels. Acetaminophen relieves mild to moderate pain from various causes, including headache. Dichloralphenazone has a calming effect to help you relax.
