What is brompheniramine, dextromethorphan, guaifenesin, and phenylephrine (AccuHist PDX Syrup, Allanhist PDX Syrup, Bromhist-PDX, EndaCof-PD)?
Brompheniramine 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.
Guaifenesin is an expectorant. It helps loosen congestion in your chest and throat, making it easier to cough out through your mouth.
Phenylephrine 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 phenylephrine is used to treat runny or stuffy nose, sneezing, itching, watery eyes, cough, chest congestion, and sinus congestion caused by allergies, the common cold, or the flu.
Brompheniramine, dextromethorphan, guaifenesin, and phenylephrine may also be used for purposes not listed in this medication guide.
