- December 23, 2013, 03:27:22 PMThanks everyone. I did call the pharmacy and was told by the pharmacist that he has seen Allegra prescribed up to 360 mg daily, but not much more than that. He also told he has seen the dose bumped up much more often with Zyrtec or Claritin and much higher. I was honestly surprised he even divulged that much info, given it is talking about going over the label. Good to know for future reference.

Fwiw, this is not advice, but know that the dosing window on most of the selective, non-sedating antihistamines? VERY wide-- at least 10x standard therapeutic dose.
Heck, even first gens are wider than a lot of OTC drugs, often as much as 5x without a problem, but they are CNS depressants. This is a problem with some medical conditions, however-- so it's a good idea to run it past a pharmacist if you have asthma or other cardiovascular conditions. Or anything else that is chronic, truthfully.

- December 22, 2013, 12:04:22 PMWell, I can tell you I've taken benedryl with allegra and been ok. Pretty sure I've also accidentally took allegra twice in one morning and was ok. Not recommending, just saying I don't think it'll kill you if you do...

- December 22, 2013, 11:51:46 AMDoes anyone know if you can take more than 1 allegra? I've been told by an allergist to take multiple zyrtec for hives (not for food reactions), and recently switched. Care to guess what started less than 24 hrs after the first dose?
