I am seeing a new PM doc. He has me on Oxycontin 20mg/2xper day. When I started seeing him, he had me on OxyC 10mg/3x per day. At that time he was going to give me percocet for breakthru, but I told him I still had some from my last doc. He said to take them in between the Oxy C. My question is this, I have a script from the old PM doc, he gave me 2 scripts for the percocet, and posted dated them a month apart. The 2nd script is now due for a filling. Is it ok to fill this since I had it before I ever saw my current doc? Also, I have 2 refills on my norco from the same doc that gave me the percocet, again, given to me before I started seeing the new doc. Is it ok to fill these as well? I dont have any meds for breakthru, and havent since my current doc changed my dose of Oxycontin. He didnt mention breakthru meds like he did with the first visit, and I forgot to ask. I am thinking that since he said it was ok to use breakthru meds the first time, shouldnt this still apply? I need breakthru meds, or an increase to 3x per day doseing with my primary med, as it does not last the 12 hours that it is supposed to. Thanks for the advice.
