Why is this drug
prescribed?
Return to top
Entex LA is used to treat
bronchitis, the common cold, sinus inflammation, nasal
congestion, and sore throat.
Entex LA is a combination of two
medications, phenylpropanolamine (a decongestant) and
guaifenesin (an expectorant), specially formulated to
deliver prolonged action. Phenylpropanolamine helps
reduce congestion in the nasal passages, while
guaifenesin breaks up mucus in the lower respiratory
tract, making it easier to clear the passages.
Most important fact about this
drug

Certain medical conditions can

high blood pressure, or diabetes, make sure the doctor
knows about it. The phenylpropanolamine in Entex LA can
raise blood pressure and speed up the heart, and can put
you at a greater risk of heart or blood-vessel disease if
you are diabetic.
