Ah, nothing like reviving a year-old thread, right? But summer’s coming around again, and this may be coming back up.
I had issues with my infusion set sweating out, and I finally found the solution was not to try to stop the sweat from dissolving the glue. No antiperspirant on the skin before putting in the set, no super-strong glue/adhesive helps. Instead, I used an ACE bandage elastic wrap or a back support to keep the set in place when I was sweating. Then, when I cooled down and stopped sweating, I found the glue re-adhered, and I could take the support off.
Any time I tried to use extra tape to hold it in place, I invariably found that tape pulling away, and then pulling out the infusion set.
Details of my setup: I do use smith&nephew’s Skin-Prep sprayed over a large area of the abdomen, and air dried for a few minutes before attaching a MiniMed Quick-Set infusion set (which is a cloth disk about 1.5 inches in diameter holding in the set).
