Bad allergies. Claritin, Zyrtec, chlor tabs, and Benadryl (diphenhydramine) no help. Little relief from allegra. Can't use nasal spray or Saline. Any suggestions?

Keep taking.. The allegra (fexofenadine) regularly, not on as needed basis, and see your doctor, you may need prescription medications. Environmental control is important too, i.e. Avoid triggers of your allergies, cats, dogs, smokers, etc.. Better if you can see an allergist, check aaaai.org or acaai.org for an allergist in your area, good luck.
