How long do i have to wait after taking allegra (fexofenadine) before i can eat a large high fat meal? it says not to take with high fat meal.

About 3-4 hours: Peak concentration after a dose of Allegra (fexofenadine) is in about 2&1/2 hours. Thus eating your high fat meal about 3 hours post a dose would be helpful.
