Coricidin contains 30mg of Dextromethorphan HBr and4mg Chlorpheniramine Meleate. Recreational use of this product should be avoided. High doses ofChlorphenniramine Meleatecan cause severe and life-threatening symptoms including seizures, loss of consciousness, bleeding from skin, mouth, rectum, and vagina, and possibly death. Some brands, including Coricidin Cough and Cold contain Chlorpheniramine maleate. I hope this will educate anybody who is not aware of the dangers of abusing Coricidin.
