If the lotion helps, great! But if you need more ideas... I have gone through a couple different phases/versions of tape irritation, and here's what I've learned:
(All products I mention can be found on Amazon and purchased without a prescription, and most are also available from your pump company. Speaking of pump company, if you call and tell them you are having tape issues they can usually send you samples of tapes and wipes and stuff so you can figure out what works best without having to buy an entire box of each to test.)
1. Different infusion sets use different adhesives, so it can be sometimes worth it to see if a different set can take care of the problem.
2. There's liquid stuff you can put on skin before you put in an infusion set to keep the adhesive from actually touching your skin- SkinTac, Mastisol and IVPrep are pretty common- and I think most come in both individual wipes or in bottles.
(Small caveat: these things also help the tape stick better, so you might need an adhesive remover in addition, but those are also pretty easy to find on Amazon or similar.)
3. If you find that its not ALL adhesives causing irritation, you can put a piece of tape like Tegaderm, IV3000 or... I've forgotton what the other one is called that I used to use, but you can stick a big piece of tape on your skin, and just stab the infusion set right through it.
4. Itchy while its on is unpleasant for sure, but if when you peel it off you see red splotchiness where the tape was, thats often an indication that the tape actually peeled off a layer of skin, and either using the adhesive barrier wipes (skin-tac, IV prep) can help with that, or just the adhesive remover wipes to help loosen up the adhesive before you rip it off can make a good difference too.
