I have had this problem so many times.....I have reactions eventually to all dressings on me.. I have to have dressing changes at least every three days..... Tegaderm is the worst..I can only last a day or so with one of those on and then I am sweating, itching and broken out..
Currently Sobraveiw is my favorite dressing along with IV3000.. They work good... I have about three or four different dressings that I rotate out with and that works best for me...
Sorbaveiw is most gently, most supportive and if all else fails I have something called Stratasorb which is not ideal becasue you can't see the insertion site but it is light, and when I really need a break I use that.
Call you home infusion nurse, they should have an arsenol of supplies to help you.
Hope this helps..
