Can I use Flonase and take Claritin and Zyrtec in the same day?

Yes. No expected benefit of combining Zyrtec and Claritin (there are situations that call for high dose antihistamine use, but generally with one or the other). Both are safe when used in combination with Flonase.

My allergies are unbearable today. I take Zyrtec and Flonase daily and they did nothing. I took Allegra too with no relief, can I also take Claritin (loratadine)?

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. Read more...
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. Read more...
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). Read more...
