What is chlorpheniramine and pseudoephedrine (AccuHist Drops, Allerest Maximum Strength, Brexin L.A., Colfed-A, D-Amine-SR, Dayquil Allergy, Deconamine, Dicel, Dicel Chewables, Durafed, Dura-Tap/PD, Duratuss DA, Dynahist-ER Pediatric, Genaphed Plus, Histade, Histex, Kronofed-A, Kronofed-A-Jr, LoHist-D, Mintex, Neutrahist Drops, Re2+30, Rescon-Ed, Suclor, SudaHist, Sudal-12 Chewable, Sudal-12 Tannate, Sudogest Cold & Allergy, SudoGest Sinus & Allergy, Tavist-DA, Triaminic Cold and Allergy, Triaminic Softchew Cold and Allergy, Triaminic Softchews Allergy Runny Nose and Congestion)?

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

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

The combination of chlorpheniramine and pseudoephedrine is used to treat symptoms of the common cold or seasonal allergies, including sneezing, runny or stuffy nose, and itchy, watery eyes.

Chlorpheniramine and pseudoephedrine may also be used for other purposes not listed in this medication guide.
