Hi I am on 75 mcg Duragesic patch for the past 4-5 years. I have found it only sticks well on my back. Warmth helps with sticking; holding hand over patch for 90 seconds or so after applying it will help it attach. Patches usually flake off when too dry. I live in Florida, but am bed-ridden a lot- but it's more likely that a shower w/ direct spray pressure and rubbing it dry w/ towel would make it vulnerable to peeling off. Your children are not at any significant risk if your patch is covered by clothing and your patch is not compromised by cuts, etc. Generally you would have to cut it on purpose to cause leakage (exception: there was a generic recall on the 25 mcg patches due to defects) but in general they are not a problem for this. Dispose of where your child cannot reach and you are pretty safe from them being in any possible danger, touching the outside of the patch on your skin won't do anything. The patch needs many hours (if uncompromised by cuts, etc) to start to go into your tissue (unlike pain meds that go directly into your digestive system. This is why it's good for me, I have Crohn's disease, and fibro and arthritis. I also take Percocet 10/325 for B/T. The patch BYPASSES being ingested, and thus protects your gut from problems with ingestion of pills. People like me are told not to take anything but tylenol due to corrosive properties of other NSAIDs. so hydrocodone/tylenol pills and Duragesic (fentanyl) are a better choice for those with gut disorders. Only caveat that i can think of which isn't a factor for me since i suffer from the opposite, is that most opiates have potential constipating factors (due to "slowing you down") but since Duragesic goes directly into tissue, not your gut, it's better than most if you have problems with your digestive system. Hope this helps, and I hope I am not too late for your posted question. If you have any more questions about Duragesic, I would be happy to help. Be well.
