Alka-Seltzer Plus Cold Formula

Generic name: Aspirin, Chlorpheniramine, And Phenylephrine
Drug class: Upper respiratory combinations

Usage of Alka-Seltzer Plus Cold Formula

Aspirin is in a group of drugs called salicylates (sa-LIS-il-ates). It works by reducing substances in the body that cause pain, fever, and inflammation.

Chlorpheniramine is an antihistamine that reduces the effects of natural chemical histamine in the body. Histamine can produce symptoms of sneezing, itching, watery eyes, and runny nose.

Phenylephrine is a decongestant that shrinks blood vessels in the nasal passages. Dilated blood vessels can cause nasal congestion (stuffy nose).

Alka-Seltzer Plus Cold Formula is a combination medicine used to treat fever, body aches, runny or stuffy nose, sneezing, itching, watery eyes, and sinus congestion caused by allergies, the common cold, or the flu.

Alka-Seltzer Plus Cold Formula may also be used for purposes not listed in this medication guide.
