I'm sure this question is addressed somewhere on this site, but I couldn't find it. How long do appliances (bags, pouches) last? I've heard that at some point the adhesive starts to break down. I recently have been having to change my pouch much more often. I have a wound where my old colostomy stoma was and in order to change the dressing, I'm constantly compromising the adhesion of my pouch, as one overlaps the other a bit. I decided to start using up some of my older pouches that are not really my favoutite products, as I really don't care if I only get a couple of days wear time with them. I noticed when tearing the backing off the flange, that it comes away pretty easily. These would be close to a year old, and I have some that are probably closer to two years old. Would they still be OK, or should I chuck them? I'm sure I could get an answer to my question by contacting one of the manufacturers, but I'm thinking I might get a more realistic answer from you guys. Thanks!
