A member asked:

I had a colonoscopy on weds. i had an adverse reaction to the fentanyl. it's now sunday and i am still not feeling normal. how long will it take?

A doctor has provided 1 answer

Why arfe you on: fentanyl? Not a drug used in colonoscopy , used for severe pain. There side effects will take 24-48 hrs to resolve. assuming you are not mixing it with any other mediciation or narcotics.
