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.

  • Follow the directions provided by your healthcare provider or the instructions on the medication label carefully.
  • Shake the bottle well before each use to ensure proper mixing of the medication.
  • Measure the prescribed dose using the provided measuring device (usually a special measuring spoon or cup). Do not use a regular household spoon, as it may not provide the correct dosage.
  • Take Entex LQ orally as directed by your healthcare provider, usually every 4 to 6 hours as needed.
