Dr. Al Hegab answered

Specializes in Allergy and Immunology

Desloratadine: (Aerius) is a second generation antihistamine, anxiety, palpitations and sleeplessness aren't known side effects of the drug, or is it combined with a decongestant as pseudo-ephedrine, which would have the said side effects? at any rate it would clear from your system in 2-3 days, its half life is about 27 hours, best wishes
