Are you on 60mg as a total daily dose? Are they extended release pain meds or short acting meds? This will make a difference in how you try to stop them. If you are taking an extended release 60mg is a fairly high dose and to cut it down to 30 is a huge drop and you will get some withdrawals. How long have you been on pain meds? What about other pain meds before the Oxycodone? If you just started taking them you should not have that hard of a time getting off of them. It takes several weeks to develop a dependency unless you are taking large amounts at a time, then it can happen much faster. The rule of thumb for tapering is to decrease 10 to 20 percent at a time every one to three days. If you have enough left you would want to reduce by ten percent and stay at that level for three to four days then go down another ten percent and so forth. That would usually make it very bareable for most people who have been of stronger meds for longer periods of time. But you have to have enough in stock to be able to do it that way. If you don't and you have not been on them that long there is really no need to draw it out. You could cut it in half every day and should be fine if you are truly not dependent. You would know with how your body is feeling. This is something you really need to be talking to your doctor about. If you are this concerned about it your doctor should be clued in. That is what they are there for. Thery are there to help you. IF they prescribe these drugs they should make it to where you can get off of them in a reasonable manner.
It's always a smart idea to be prudent when taking narcotics. I wouldn't think being on it for five days would cause a dependence. And if you're not dependent, then you wouldn't need to worry about withdrawals. But if someone were dependent, 30 mg. would be a significant drop. Rather than do this on your own, it would be better to talk with the doctor that prescribed this for you. As long as you are taking it as prescribed by your doctor, you should be okay. There's no reason to suffer with pain after a surgery or procedure.
