A member asked:

Can allegra work the same as benadryl (diphenhydramine)?

A doctor has provided 1 answer

Antihistamines: Both are antihistamines. Benadryl (diphenhydramine) works for a maximum of 6 hours, Allegra works for 24. Allegra is non drowsy but Benadryl (diphenhydramine) is very sedating.

Dr Pappas and another doctor agreed
