I had a patient yesterday, that gets 20mg Oxycontin long acting bid. He asked me to cut it into fours for him b/c he only wanted to take 5mg of oxycodone at a time. I told him that long acting med's should not be cut or crushed due to the medicine being absorbed all at once, and possibly causing an overdose. He then told me that it would only be 5mg of the medicine all at once, ( just a little too educated for my taste on narcotics) and he wanted to see if that would be all he needed to help with the immediate pain, and then would not want anymore if so. I was stuck. It makes sense that it would only be 5mg, but I didn't feel comfortable telling him (or agreeing with him and going against the "laws of long acting"), plus.. honestly... I don't know. I again reinforced that they should not be cut or crushed, and if he felt he doesn't need the entire 20 dose, I could talk to the doctor about cutting the DOSE for him. He said he'd talk to him.. however.. I still don't know. p.s. I didn't cut the dose.
