Acetaminophen / dichloralphenazone / isometheptene mucate
"This was the first medication I received for my migraines, and it worked for 90% of my migraines.  However, the side effects left me dizzy, disoriented, drowsy, and just generally intoxicated and unable to perform normal work.  I switched to Fioricet, and it's been a much better experience since."
