In brief: No
It is not advisable to take 2 or more antihistamines together without md supervision.
Taking multiple antihistamines together will not cause increased allergy symptoms or hives and if used properly under md supervision multiple antihistamines can control difficult to treat symptoms.

No but it is not a good idea to take all three or even two together unless adviced by your doctor for very short period, that is onle Allegra or zyrtec in am and Benadryl (diphenhydramine) one dose at bed time.
