Brand Names: Donatussin

Generic Name: chlophedianol, guaifenesin, and phenylephrine (Pronunciation: KLOE fe DYE a nol, gwye FEN e sin, and FEN il EFF rin)

What is chlophedianol, guaifenesin, and phenylephrine (Donatussin)?

Chlophedianol is a cough suppressant. It affects the signals in the brain that trigger cough reflex.

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 chlophedianol, guaifenesin, and phenylephrine is used to treat stuffy nose, cough, chest congestion, and sinus congestion caused by allergies, the common cold, or the flu.

Chlophedianol, guaifenesin, and phenylephrine will not treat a cough that is caused by smoking, asthma, or emphysema.

Chlophedianol, guaifenesin, and phenylephrine may also be used for purposes not listed in this medication guide.
