Description:

Expectuss Liquid is an alcohol-free, sugar-free, purple liquid for oral administration having a grape odor and flavor.

CARBETAPENTANE CITRATE 20 mg
GUAIFENESIN 75 mg

CLINICAL PHARMACOLOGY:

Carbetapentane citrate is a centrally acting non-narcotic antitussive.

Guaifenesin is an expectorant. Its action increases the output of respiratory tract fluid by reducing

the common cold, influenza, sinusitis, and bronchitis.

CONTRAINDICATIONS:

Expectuss Liquid is contraindicated in infants, newborns, and in patients with a known
hypersensitivity to any of the components. It is also contraindicated in patients on MAO inhibitor therapy.

WARNINGS:

A persistent cough may be a sign of a serious condition. If cough persists for more than one week
or tends to recur, or is accompanied by fever, rash, or persistent headache, patient reevaluation
should be considered.
