Codeine/diphenhydramine/phenylephrine solution is a decongestant, antihistamine, and cough suppressant combination. It works by constricting blood vessels and reducing swelling in the nasal passages. The antihistamine works by blocking the action of histamine, which helps reduce symptoms such as watery eyes and sneezing. The cough suppressant works in the brain to help decrease the cough reflex to reduce a dry cough.
