What is guaifenesin and phenylephrine (Entex La)?

There are many brands and forms of guaifenesin and phenylephrine available and not all brands are listed on this leaflet.

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

Guaifenesin and phenylephrine may also be used for purposes not listed in this medication guide.
