Common brand names:
This medication is used to relieve allergy symptoms such as watery eyes, runny/stuffy nose, itching eyes/nose, and sneezing. It contains 2 medications: fexofenadine and pseudoephedrine. Fexofenadine is an antihistamine and works by blocking a certain natural substance (histamine) that your body makes during an allergic reaction. Pseudoephedrine is a decongestant and works by narrowing the blood vessels in the nose to decrease swelling and congestion.
This medication is not recommended for use in children under 12 years of age due to the large amount of pseudoephedrine in it.
How to Use This Medication
If you are taking the over-the-counter product to self-treat, read all directions on the product package before taking this medication. If you have any questions, consult your pharmacist. If your doctor has prescribed this medication, take it as directed.
Take this medication by mouth on an empty stomach (at least 1 hour before or 2 hours after a meal). Take this medication with water. Do not take with fruit juices (such as apple, grapefruit, or orange) since they may decrease the absorption of this drug.
Do not crush or chew extended-release tablets. Doing so can release all of the drug at once, increasing the risk of side effects. Also, do not split the tablets unless they have a score line and your doctor or pharmacist tells you to do so. Swallow the whole or split tablet without crushing or chewing.
The dosage is based on your medical condition and response to treatment. Do not increase your dose or take this medication more often than directed.
Do not take antacids containing aluminum and magnesium within 2 hours of taking this medication. These antacids can decrease the absorption of fexofenadine.
Tell your doctor if your symptoms do not improve after 1 week, if they worsen, or if they occur with a fever.
