You know how miserable your allergies can be—and how some antihistamines can make you feel. That’s why Allegra was made to give you nondrowsy relief. In fact, in tests conducted by allergists, drowsiness in people who took Allegra was similar to placebo (sugar pill), 1.3% vs 0.9%.
The most commonly reported adverse events with Allegra and placebo are cold or flu (2.5% vs 1.5%), nausea (1.6% vs 1.5%), and menstrual pain (1.5% vs 0.3%). Most important of all, Allegra is safe to take as prescribed, without worrying that its effectiveness will wear off as the day wears on. Allegra works on your seasonal allergy symptoms: your itchy, watery eyes plus sneezing and runny nose.

Allegra-D for Stuffy Noses Allegra works on your seasonal allergy symptoms: your itchy, watery eyes, plus sneezing and runny nose. But if you find your nose is stuffed up too, you should ask your doctor about Allegra-D. Allegra-D has the same antihistamine as Allegra with the added relief of a decongestant.
Because Allegra-D contains pseudoephedrine (the decongestant in most over-the-counter allergy medicines), Allegra-D must not be taken if you are also taking MAO inhibitors (medicines that treat depression) or if you retain urine or have glaucoma, severe high blood pressure, or severe heart disease. Also, let your doctor know before you take Allegra-D if you have high blood pressure, diabetes, heart disease, glaucoma, thyroid disease, impaired kidney function, or symptoms of an enlarged prostate such as difficulty urinating. The most commonly reported adverse experiences with Allegra-D compared to pseudoephedrine alone were headache (13.0% vs 17.4%), insomnia (12.6% vs 13.3%), and nausea (7.4% vs 5.0%).
