Hello psminker.
I do feel for you in this situation as adhesives that cause a bad reaction are not what you want or need with a stoma.
My wife has a similar reaction to medical plasters and has to find alternatives.
My own approach to begin with would be to try different adhesives on parts of your body away from the stoma to see if there is an adverse reaction.
I gave up trying to stick manufactured wafers to my skin because they simply did not stay stuck! However, they do stay stuck on my own base-plates which I have been sticking down with Hollister 7730 medical adhesive spray. Unfortunately, Hollister have decided to discontinue this line, so it is doubtful whether you would be able to get any now, All is not lost, as there are other alternative medical adhesives on the market, which may or may not be useful for you.
Alternatively, I have opted to trial a 2.5inch double edged adhesive tape from Korea called 'sookwang'. So far it is doing well, but prior to that I was using commonly available at the local DIY store, double sided carpet tape.
I have mentioned this next 'trick' in previous posts but these things are often worth putting out there again: I have successfully used 'artificial skin', which is used in the film industry for 'make-up' . This sticks to the skin temporarily, and then you can stick whatever you like to it without the secondary thing touching your skin.
A similar effect can be obtained from Bayer's Germolene new-skin liquid plaster. However, I found that this is not good if any of the skin is broken and, for me, it is a bit like superglue, in that it sometimes doesn’t come off easily when I want it to.
Many people find that Micropore is better on the skin than normal adhesive plasters and Micropore comes in different sized roles. This can be used as a base layer before applying either the wafer or a double-sided tape for a base-plate of your (my) own making.
With most things stoma-related, I find that experimenting to find what suits 'you/me' is the best way to find solutions to irritating problems. As mentioned previously, for people who react badly to adhesives, it would seem sensible to try these things on parts of the body that are less likely to cause major problems if they cause an adverse reaction. This way, at least you will know what not to use.
I do hope you are able to find a solution to your problem soon, in the meantime, I will share with you (below) some of the contacts I have found to try to find a replacement for 7730 :
Best wishes
Bill
