A member asked:
Does taking benadryl (diphenhydramine) affect vyvanse the next day?
A doctor has provided 1 answer
No, it should not.: There should be no adverse interaction with the two. Many patients take Benadryl (diphenhydramine) for sleep and their vyvanse in the morning. If concerned, always follow up with your prescribing physician.
