What is MonteCough?

Carbetapentane 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).

MonteCough is a combination medicine used to treat stuffy nose, sinus congestion, cough, and chest congestion caused by sinusitis, bronchitis, or the common cold or flu.

MonteCough may also be used for purposes not listed in this medication guide.
