How long does it take for Allegra to take effect?
Hi. I think Loulu2u said it well. Here is some more information: . Fexofenadine (Allegra) is in a class of medications called antihistamines. It works by blocking the effects of histamine, a substance in the body that causes allergy symptoms. Whats great about it is that it is NON SEDATING – Claritin can make you drowsy at higher doses and Zyrtec’s regular dosing can have sedating effects. There are several versions of Allergra including those with Pseudophedrine (Allegra D), orally disintegrating tablets, and various dosaging (180mg, 120mg, & 60mg) options. I have such severe allergies (year round – but Trees/Grasses/Molds are my worst) that I take the 180 mg dose twice a day. I have had no adverse side effects. At times, I take a decongestant (pseudophedrine) along with the fexofenadine to help with the extra stuffies of the bad reactions. I did some research to help figure the answer to your question. I found your answer and a bit more. Maybe the info here is too much – but atleast
