A member asked:
I took 24 hour on drowsy allegra for 3 days and then stopped. now i can't stop itching. how long will this last and is there anything i can do?
A doctor has provided 1 answer
Try benadryl: It is unusual to develop an allergy to allegra. Could whatever you took the allegra for be causing the reaction? Try taking benadryl.
