Non sedating antihistimine
Those newer antihistamines have been widely advertised, so you might recognize some of the brand names—Allegra, Claritin, Clarinex, Zyrtec, and Xyzal.
While the second-generation antihistamines can help relieve allergy symptoms, they usually don’t clear them up entirely.
Both Flonase and Nasacort are recently available without a prescription.Medications called "second-generation" antihistamines have eclipsed older antihistamines, such as Benadryl, chlorpheniramine (e.g.Chlor-Trimeton Allergy); clemastine (Tavist); brompheniramine (Dimetapp); and diphenhydramine (Benadryl Allergy) for treating allergy symptoms because they are less likely to cause sedation and drowsiness.While fewer people experience serious sedation with the newer antihistamines, the labels on these drugs still warn people not to drive or operate machinery until you know how they affect you.Most of the newer antihistamines need to be taken just once a day while the older ones must be taken two or more times a day because their effect wears off more quickly.
