Carbaphen 12 liquid

Generic Name: phenylephrine/chlorpheniramine/carbetapentane (FEN-il-EF-rin/KLOR-fen-IR-a-meen/kar-bay-ta-PEN-tane)
Brand Name: Carbaphen 12

Carbaphen 12 liquid is used for:

Relieving symptoms of sinus congestion, runny nose, sneezing, and cough due to colds, upper respiratory infections, and allergies. It may also be used for other conditions as determined by your doctor.

Carbaphen 12 liquid is a decongestant, antihistamine, and cough suppressant combination. The 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.
