Drug Testing; Does anyone know the detection time for Fentanyl/Duragesic (.75mcgr) patches. My pain specialist wants to see me before he issues another prescription because my last test came back clean. I told the nurse I had not been on a patch for (4) days and I take Oxy-Clean, which is a program to clense your system out and she said the Fentanyl stays in your system 30 days. I told her I think she is wrong and I want to see the doctor. I will keep you posted. Let me know if anyone knows the detection times. Thank you!
Just a thought here but you might get a much better response if you asked this question down on the pain management board.personally,I seriouly doubt that fent would stay in your system for that long,really.the only actual drug that I know of that stays in the sytem that long length of time would be marijuana,and thats because it is actually stored in the fat cells.
the majority of pain meds realistically would probably not go for more than one week at best.but since the delivery system is a bit different I cannot say for sure just exactly how this drug would maintain itself within a given body system tho.
just so you know there have been many cases of false positives and negatives with any urinalysis for a host of reasons,that is why when something just doesn't "appear to be just right" they will normally order a retest.Just from my experience at having to undergo the same type of UAs at my pain clinic,i know just how important it is that what you are supposed to be taking actually shows up in your system.just go on down to the pain board.there are many people there who really do know alot about basic UAs as most of us there are in some sort of a contracted pain management program.good luck,Marcia

I think the half-life of the fentanyl patch is 17 hours. In theory, most drugs are cleared out of your system in 5-6 half-lives (unless they are fat soluble, as previously mentioned). So, in theory, if you remove the patch, the drug would effectively be cleared from your body in about 85-102-hours which corresponds pretty closely with the 4-day time that you described.
Snice is right about the half-life of Fent. The unique thing with the patch is that the fent is stored in the skin beneath the patch. It builds up a small reservoir under the patch/skin.
Once the patch is removed serum concentration fall about 50% in 17 hours. I would say it is detectable around 4 days, 5 days at the most depending on how many applications you use, where you use them, and how long you have been on them.
Its odd that if the doc knew you had been off for 4 days, that he would put too much weight into the test.
Good luck in getting it straightend out. I agree with talking to the doc though. Your nurse is giving some inaccurate info.
Thanx for the replies, I have been on the patches for about 2 years. I take about 4-5 days break to clense my system out every few months. It enables the meds to work better, clense my system out, bowels and all and most of all improves my sex life. There are other meds involved but the patches are my GOD send. Me & pills don't get along. can't get enough to control the pain. I just hope he does not think I can go without patches 4 days all the time.....I can see that argument coming or him telling me to take another pee test which will enrage me cause it will cost me time and all of us money.....insurance or not we pay it one way or another.
I have an appt tomorrow at 1000 am and I will let you know what happens.
Wish me well...........
WELL THIS DOC IS SOOO SCATTERED BRAINED BUT HE DOES A GOOD JOB. HE IS ALWAYS LATE FOR HIS APPOITMENTS/PROCEDURES BUT ANYHOW
TODAY.........HE FORGOT WHY I WAS THERE UNTIL I TOLD HIM. HE SAID HE WANTED TO SEE RECEIPTS FOR THE BODY CLENSE SYSTEM. HE ASKED ME IF I WAS USING ANY OTHER PAIN DRUGS AND IF THAT IS WHY I DO THE BODY CLENSE? JUST GIVE ME MY PRESCRIPTION SO I CAN LEAVE...BUT WAIT....HE WANTS ME TO PEE AGAIN....GHEESHH...DO I GET MAD AND THROW A FIT, NOPE, I SAID GIVE ME A CUP AND DON'T BE SURPRISED IF IT COMES BACK CLEAN......THAN I FINALLY GET A SCRIPT...WHAT B.S. WELL FOLKS TAKE CARE AND SEE YA AROUND.........
