Why is this medication prescribed?

Entex LA is a combination medication used to relieve symptoms associated with respiratory conditions such as congestion, cough, and nasal discomfort. It contains two active ingredients:

• Guaifenesin: This is an expectorant that helps loosen mucus in the airways, making it easier to cough up.
• Phenylephrine: This is a decongestant that works by narrowing blood vessels in the nasal passages, which reduces swelling and congestion.

Entex LA is typically prescribed to alleviate symptoms of conditions such as the common cold, flu, allergies, or sinusitis.

How should this medicine be used?

Entex LA should be used exactly as prescribed by a healthcare professional. It’s essential to follow the dosage and administration instructions provided on the prescription label or as directed by the healthcare provider. Here are some general guidelines for using Entex LA:

• Dosage: Take Entex LA exactly as prescribed by your doctor. Do not take more than the recommended dose, and do not take it more frequently than prescribed.
• Administration: Swallow the extended-release tablet whole with a full glass of water. Do not crush, chew, or break the tablet, as this can release the entire dose at once, increasing the risk of side effects.
• Timing: Take Entex LA with or without food. However, taking it with food may help minimize stomach upset.
• Frequency: Take Entex LA at the same time(s) each day to maintain a consistent level of the medication in your body.

Do not share Entex LA with others, even if they have similar symptoms, as it may not be safe or effective for them. If you miss a dose of Entex LA, take it as soon as you remember. However, if it’s almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one.
