Can Suboxone Be Taken With Other Opiates?

I have been taking the medication Suboxone for almost 12 months now. I ve been tapering myself down, & am currently at 2mg/day. Here s my dilemma-- I m scheduled for laporoscopic surgery in about 20 days (Feb 15). I ve tried talking to my gynecologist (the Dr. performing surgery) regarding necessary precautions to take, but he told me to speak with the Dr. prescribing the Suboxone. So I spoke to that Dr. & he advised me it would be fine to take Sub up to the day of surgery, & then continue to use it as often as needed for pain. Is this correct? I m worried about not getting adequate pain relief. I m also concerned because I was under the impression that the Suboxone could cause me to go into harsh withdrawals if taken too soon with other opiates. But won t I be getting other opiates while sedated during & after surgery? Please help!!
