What is brompheniramine, dextromethorphan, guaifenesin, and pseudoephedrine (Bromhist-DM, Histacol DM Pediatric Syrup, Pediahist DM Syrup)?
Brompheniramine is an antihistamine that reduces the natural chemical histamine in the body. Histamine can produce symptoms of sneezing, itching, watery eyes, and runny nose.
Guaifenesin is an expectorant. It helps loosen congestion in your chest and throat, making it easier to cough out through your mouth.
Pseudoephedrine is a decongestant that shrinks blood vessels in the nasal passages. Dilated blood vessels can cause nasal congestion (stuffy nose).
The combination of brompheniramine, dextromethorphan, guaifenesin, and pseudoephedrine is used to treat sneezing, runny or stuffy nose, cough, chest congestion, itchy or watery eyes, hives, skin rash, itching, and other symptoms of allergies and the common cold.
