Coricidin, Coricidin 'D' (decongestant), or Coricidin HBP (for high blood pressure), is the name of an over-the-counter cough and cold combination drug containing dextromethorphan (a cough suppressant) and chlorpheniramine maleate (a first-generation antihistamine). Introduced by Schering-Plough in 1949 as one of the first antihistamines, it is now owned by Bayer. Varieties of Coricidin may also contain acetaminophen (an analgesic/antipyretic) and guaifenesin (an expectorant).
