Is it possible for fentanayl to still be in your system nineteen days after surgery?

Answer 1

Absolutely not, unless you are using a Fentanyl patch, such as Duragesic or another brand name for the opiod-based transdermal pain delivery system , in which case, the Fentanyl will remain in your system, as provided by the patch, until about three to five days after you remove the last patch. There is no way for a urine drug test to determine whether the Fentanyl (opiod narcotic) it is detecting is that which was used to relieve your pain in surgery (or what was given to you by the anesthesiologist while you were asleep) or that which is entering your system now from the pain patch, except to say that at nineteen days "post op" nothing given to you in the operating room will still be in your system, so it would have to be something like a pain patch, unless perhaps you were given an injection of Fentanyl into your spinal area, such as an intrathecal injection, meant to linger there in that area and absorb over a period of many days and provide longer term pain relief, but you would certainly have been told and have had to approve a procedure of that sort and would therefore be aware that it was given to you prior to leaving the hospital/surgi-center as a longer-term pain reliever. In that case, a test would identify the Fentanyl in your system at likely many days (not sure how many, it would depend on the dosage and how long the medication was intended to linger there). Hope that helps out.
