Take your medications as prescribed and save yourself the worry of them showing up anything but "properly" on you urine test. If your medication isn't working well, speak with the doctor BEFORE you start "running low". Honesty is the best policy........... Do unto others......etc.,etc.,........I omitted a lot of what I was going to (and wanted to say) in this post. A few - - - apples..........
I could probably give you better advice if you can give me some more details, like: What kind of pain are you having? What kind of testing have you done and what kind of doctor are you seeing? There are many different meds that work for different kind of pain. Also a extended release med might be a good choice, but again, it depends on your pain.
What comes after these medications? i swear they only work rarely and even then it's like an every other month type of thing. i think I've run the gamut of hydrocodone and percs. any advice?
It doesn't really matter. They will ask you when you took it last and they would be able to tell based on that. Depending on what kind of UA they use, they could possibly tell your average use. If its just an in-office thing then a few hours should be ok.
