I am being taking geritol, emergenc, dayquil, plus y multivitamins. does any of those affect my birth control pill?

Unlikely, but . . .: It's unlikely that any of your dietary supplements will affect your birth control pill but w/o knowing exactly which one you're taking, we can't give you a definitive answer. Worse, there are more than a half-dozen versions of "Dayquil", each w/different ingredients, so again, not enough information. Consider using http://www.drugs.com/drug_interactions.html. More importantly, talk w/ur FamilyDoc
