A member asked:
Please tell me, could i take nyquil and allergy medicine together?
A doctor has provided 1 answer
Antihistamine: Nyquil has Diphenhydramine in it, i believe, which is Benadryl (diphenhydramine) which is an allergy medicine and causes somnolence. The dose is not high enough and long acting to preclude the use of the daytime, non-drowsy allergy medicine to help you during the day.
