What is Allegra Medicine Used For?

Allegra is a popular over-the-counter (OTC) antihistamine medication used to relieve symptoms of seasonal allergies, such as sneezing, runny nose, and itchy eyes. It contains the active ingredient fexofenadine, which works by blocking the release of histamine, a substance in the body that causes allergy symptoms [1].

How Does Allegra Compare to Other Allergy Meds?

Allegra is often compared to Claritin (loratadine) and Zyrtec (cetirizine), other popular OTC allergy medications. While all three work similarly, Allegra is generally considered to be a more effective option for moderate to severe allergy symptoms, with faster relief and longer-lasting effects [2][3].

Why Are Patients Using Allegra?

According to data from DrugPatentWatch.com, Allegra's popularity has remained steady over the years, with millions of patients using the medication every year to manage their seasonal allergy symptoms [4].

What Are the Side Effects of Allegra?

Like all medications, Allegra can cause side effects, such as dizziness, headaches, and fatigue. In rare cases, more serious side effects, such as allergic reactions, may occur. Patients should consult their doctor or pharmacist before taking Allegra, especially if they have a history of allergies or are taking other medications [5].

When Does Allegra Patent Expire?

The Allegra patent has expired, allowing generic versions of the medication to be produced and sold at a lower cost. This has made it more accessible to patients who need affordable options for managing their allergy symptoms [6].
