Other OTC drugs are much safer. I don't allow acetaminophen in the house. Pseoudoephedrine? Yes.
Acetaminophen also should not be taken as a hangover cure, due to interactions with alcohol (alcohol and acetaminophen compete for the same metabolic pathways in the liver, and this exacerbates the toxic effects of acetaminophen). The problem is that someone who's drinking and has a hangover is probably going to reach for one of the two most common OTC pain relievers in their medicine cabinet, and not consider that one of those two pain relievers should not be combined with alcohol.
