Allegra® | Allergy Medicine To Live Your Greatness.

Allegra Hives allergy medicine is made with active ingredient fexofenadine HCl, a non-drowsy antihistamine, so you can take it day or night without drowsiness.

FEXOFENADINE (fex oh FEN a deen) prevents and treats allergy symptoms, such as red, itchy eyes, sneezing, a runny or stuffy nose, or hives. It works by blocking histamine, a substance released by the body during an allergic reaction. It belongs to a group of medications called antihistamines.

Allegra® starts working in one hour - twice as fast as Claritin* - and won't leave you feeling drowsy like Zyrtec. That is why it's the #1 allergist recommended non-drowsy allergy brand.

While it's generally well tolerated, it may cause side effects for some people. Common Allegra side effects include headache, indigestion, and dry mouth. Very rarely, people may experience drowsiness or fatigue after a dose. Side effects from Allegra are usually mild and can be managed at home.

• upset stomach,
• muscle or back discomfort or pain,

Do not take fexofenadine with fruit juice (such as apple, orange, or grapefruit). These juices can make it harder for your body to absorb fexofenadine. Avoid taking an antacid within 2 hours before or after you take fexofenadine.

Key Takeaways. Newer antihistamines like Allegra and Claritin are generally safe for daily use. But allergy medications with decongestants, such as Claritin-D or Benadryl-D, could make your allergies worse with long-term use.

Trials have shown both Allegra (fexofenadine) and Claritin (loratadine) are significantly more effective than placebo (a pretend pill) for reducing symptoms associated with allergic rhinitis, hay fever, and other allergies.
