Why is this medication prescribed?

Allegra-D, which combines fexofenadine and pseudoephedrine, is prescribed to manage symptoms of seasonal allergies and nasal congestion. Fexofenadine is an antihistamine that helps relieve symptoms like sneezing, runny nose, and itching by blocking histamine, a substance in the body that causes allergy symptoms. Pseudoephedrine is a decongestant that helps reduce nasal congestion by constricting blood vessels in the nasal passages. Together, these medications help alleviate both the allergic symptoms and the associated congestion.

How should this medicine be used?

Allegra-D should be used as directed by your healthcare provider or according to the instructions on the package. Here are some general guidelines:

• Dosage: Typically, the recommended dosage for adults and children over 12 years old is one tablet every 12 hours. Do not take more than two tablets in 24 hours.
• Administration: Swallow the tablet whole with a full glass of water. Do not crush, chew, or break the tablet.
• Timing: It’s best to take Allegra-D with or without food, but try to take it at the same time each day to help remember.
• Avoid Overuse: Do not use Allegra-D for longer than directed. Prolonged use without consulting a healthcare provider can increase the risk of side effects.
• Precautions: If you have certain medical conditions (like high blood pressure, heart disease, or glaucoma) or are taking other medications, consult your healthcare provider before using Allegra-D, as it may interact with other drugs or exacerbate existing conditions.

Always follow your healthcare provider’s advice or the instructions provided with the medication.

Other uses for this medicine

Besides treating seasonal allergies and nasal congestion, Allegra-D may be used off-label for other conditions involving allergies and congestion, but such uses should be under the guidance of a healthcare provider.
