Entex Pac liquid
Generic Name: guaifenesin/pseudoephedrine (DEX-troe-meth-OR-fan/gwye-FEN-e-sin/SOO-doe-e-FED-rin)
Brand Name: Entex Pac
Entex Pac liquid is used for:
Relieving congestion, cough, and throat and airway irritation caused by colds, hay fever, or other respiratory allergies. It may also be used for other conditions as determined by your doctor.
Entex Pac liquid is a kit containing a decongestant and expectorant tablet combination and a cough suppressant liquid. The decongestant works by constricting blood vessels and reducing swelling in the nasal passages. The expectorant works by loosening mucus and lung secretions in the chest, making coughs more productive. The cough suppressant works in the brain to help decrease the cough reflex.
