Allegra

Allegra is a non-drowsy over-the-counter antihistamine designed to provide fast and long-lasting relief from allergy symptoms. It contains fexofenadine, which works by blocking histamine—the chemical responsible for allergic reactions in the body.

Allegra helps relieve symptoms such as sneezing, runny nose, itchy or watery eyes, and itching of the nose or throat. It is commonly used for seasonal allergies (like pollen) as well as indoor allergies caused by dust mites, mold, and pet dander.

Known for its 24-hour relief and non-drowsy formula, Allegra is ideal for daytime use, allowing users to stay alert while managing their allergy symptoms. It is available in tablets, liquid gels, orally disintegrating tablets (ODT), and children’s liquid formulations.

Trusted for its fast-acting and effective performance, Allegra is a go-to choice for individuals looking for strong allergy relief without feeling sleepy.
