Pain \ Pain Meds\ Urine Test

How close to a urine drug screen would I take my last 500 mcg. Fentanyl Troche for it to show up in my urine??  I happen to have a REALLY bad month & I want to make sure that it shows up positive...I can also explain to my doctor the horrible month I've have (some new pain & also some SERIOUS mental health issues with my son that I'm sure did nothing but make my already bad near daily migraines all the more worse...but was just wondering how long it would take to go thru one's system...Thanks!

I'm sorry I don't know how long it will show up in your body.  In your case I would look into of those over the counter drug tests and see if that might help you get your answer or asking your pharmacyst. I know it takes a full month for the patch to fully get into your system.
Good luck.

Thanks so much Ellen, hadn't thought about one of the OTC drug tests, wonder if fentanyl would show up in one...only thing is with just one left I wouldn't know when to take it! I'd have to get a test and try it when I get my new Rx & see how long it takes to show up in my urine, in case I have another bad month, I'm sure I will the way things are going with my son & all, anyway THANKS AGAIN for your reply!!!

Honestly I would talk to your doctor, if you're saying you had a bad month and put on an additional patch, that can kill you. Better to explain whats going on and maybe your doctor will prescribe something for breakthrough pain. The patches aren't something to be played with or increase on your own and they aren't meant to get you through anything other than pain, having mental health issues is NOT a reason to take more than prescribed. Also certain drug tests can measure exactly how much is in your system and also the average amount that has been in your system. So again, talk to your doctor. Please don't think I'm being harsh, but your doctor can drop you for this and then where would you be? Good luck to you.
