I had a colonoscopy a couple of weeks ago, and I was sedated with propofol. I have a prescription for Ativan, and I was told that I could take it the day before the procedure, but not the morning of. Anyway, I decided to discontinue it 6 days before my procedure, because I'm scared of drug interactions, even though the medical team said it was ok, I felt safer not taking it. Anyway, your best option is to ask your Dr.
