A member asked:
Could 3 benadryl (diphenhydramine) allergy (acrivastine) capsules per day cause a change in menstrual cycle; mid-cycle (around ovulation time) bleeding and late period?
A doctor has provided 1 answer
No: I am not aware of antihistamine use affecting menstrual cycles. You need to consult your gynecologist and perhaps even an allergist for your allergies.
