What is the most important information I should know about acetaminophen, dichloralphenazone, and isometheptene?
Acetaminophen is a pain reliever and a fever reducer. Dichloralphenazone is a sedative that slows down your central nervous system (brain and nerve impulses), causing relaxation and pain relief. Isometheptene causes constriction (narrowing) of blood vessels (arteries and veins). This is important in the treatment of headaches. The combination, acetaminophen, dichloralphenazone, and isometheptene, is used to treat tension (or muscle contraction) and vascular (migraine) headaches. Acetaminophen, dichloralphenazone, and isometheptene may also be used for purposes other than those listed in this medication guide.
