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.
