What are the effects of a floricet (apap/butalbital/caffeine) overdose?

Can be fatal: Butalbital is a barbiturate and in overdose can lead to coma, suppress the breathing, and lead to death. Apap = acetaminophen; overdose can lead to liver failure and death. It is very important never to take more of a medication than prescribed or, in the case of over-the-counter meds, never to take more than on the label unless otherwise directed by your doctor.If overdosed, seek emergency help.

Sedation/liver issue: The tylenol (acetaminophen) component can cause liver damage if too many are taken at once. The butalbital will cause sedation that cannot fully be overcome by the caffeine.
