A quick search on this topic will yield this gem of a thread.
is guessing that SWIY came across the Mylan
patches, which do not contain gel. The Duragesic brand patches do contain gel, which can be used in a variety of ways. Options with the Mylan patches are somewhat more limited, but they can be worn, or used patches can be chewed and the contents left to absorbed sublingually or through the mouth. This thread
might shed some more light on the topic as well.
Simply wearing the patch will cause effects to come on a lot faster than 72 hours, however. 72 hours is just the reccomended time for an opioid
-tolerant person to wear the patch to experience pain relief. SWIM has found that when he would wear patches, the onset of effects could be felt around 8-10 hours, and the patches actually contain enough fentanyl
to last 100 hours total when worn as directed.
BUT, if SWIY has little experience with opioids
, and does not have a moderate tolerance to them, SWIM reccomends not
trying to use them at all. Fentanyl is one of the strongest opioids, dose-wise, that is available, and respiratory depression and death can occur in people with no opioid tolerance after they attempt to use them. Dosage can be tricky to calculate since fentanyl doses are measured in micrograms, instead of milligrams like many drugs
, and when chewing patches, smoking gel, etc., there is oftentimes no way to accurately gauge a dose.
SWIM doesn't want to come off the wrong way, or to say unequivocally not to use fentanyl, but he has known people who have died from this drug
, particularly in the patch form due to the dosing reasons that SWIM has stated above. SWIM does not know SWIY's situation with regards to tolerance, but be EXTREMELY
careful and read up on the topic before making a decision regarding using these patches.
