Coricidin HBP Cough & Cold is an over the counter cough preparation (available in the USA) which contains 30 mg dextromethorphan hydrobromide (DXM)
and 4 mg chlorpheniramine maleate (chlorphenamine, CPM) per tablet. Because of the chlorpheniramine, Coricidin can be extremely dangerous in recreational doses. Coricidin abuse has resulted in seven (?) confirmed deaths as well as uncounted hospitalizations. Recreational use of Coricidin is strongly discouraged.
Coricidin is widely abused, primarily by minors.
Common slang names for Coricidin HBP Cough & Cold are CCC, TripleC, skittles, red dragons, etc.
