About an hour...: Allegra is an "as needed" allergy medication so it's effect is not dependent of taking every day - of course for many people "as needed" IS daily. You should start to see the effects of the medication in about an hour after taking it. If you are not noticing improvement of symptoms in a day or two, it may not be the allergy medication for you.

Allegra: Allegra can be taken when it is needed & can start working in about an hour.

Allegra (fexofenadine) D: Plain Allegra (fexofenadine) probably does not interact with any other medicines. Allegra (fexofenadine) d has 'decongestant'. It helps stuffiness. Decongestants can affect sleep, blood pressure and cause difficulty in urination in people with prostate problems. Read the brochure and don't hesitate to ask questions from the pharmacist for any over the counter medicines.
