Chlorpheniramine maleate
Chlorpheniramine maleate (or CPM) is an antihistamine with anticholinergic properties used to treat or prevent the symptoms of allergies (such as runny nose, sneezing, itching, and watery eyes) in humans and animals.
CPM is one of the main ingredients in many OTC allergy medications, such as Coricidin Cough & Cold (or CCC). Many people use Coricidin recreationally for the dextromethorphan content; however, this is strongly recommended against. In high doses, chlorpheniramine maleate can cause severe allergic reactions and has been linked to at least twelve deaths in the United States.
