Supress A liquid
Generic Name: dexbrompheniramine/dextromethorphan/phenylephrine (DEX-brome-fen-IR-a-meen/DEX-troe-meth-OR-fan/FEN-il-EF-rin)
Brand Name: Examples include Panatuss DXP and Supress A
Supress A liquid is used for:
Relieving symptoms of sinus congestion, runny nose, sneezing, itchy nose or throat, itchy or watery eyes, and cough due to colds, upper respiratory infections, or allergies. It may also be used for other conditions as determined by your doctor.
Supress A liquid is a nasal decongestant, antihistamine, and cough suppressant combination. The nasal decongestant 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.
