Why is this medication prescribed?

Entex LQ is a combination medication used to relieve symptoms of the common cold, flu, allergies, hay fever, and other respiratory conditions. It contains two active ingredients: guaifenesin, which helps to loosen mucus and make coughs more productive, and phenylephrine, which is a decongestant that helps to relieve nasal congestion.

Entex LQ is typically prescribed or recommended by healthcare providers to alleviate symptoms such as coughing, nasal congestion, runny nose, and sinus congestion associated with these conditions.
