You can, but: It is unlikely to add additional coverage after taking both Zyrtec and Allegra (fexofenadine). It is important to understand that blocking histamine receptors is not a cure-all for allergy. There are many potential symptoms that may be driving you crazy and knowing more about them will help a physician to recommend short term therapy for short term relief. See Allergist and consider virtual consult if needed.

No: You have already taken Zyrtec and Allegra (fexofenadine) . Taking another antihistaminic like Claron (Loratadine) is not advisable as you are essentially overdosing. I suggest to see your PCP as there may be a super-imposed infection. Oral corticosteroids are used in most severe cases particularly when lungs are involved.

Yes but . . .: Zyrtec, Allegra & Claritin are all 2nd generation antihistamines. Find which is best for you. Just don't take 2 or more in same 24hr period of time. Flonase is a nasal steroid that is now available w/o prescription. Try nasal antihstamine & avoid pollen & known allergens (easier said than done). If no better, go see Family Doc & Allergist for eval. Consider montelukast (leukotriene inhibitor).
