I was on HRT for 2 years with no problems and then suddenly last summer I started having a heat rash type reaction to them. I switched to the spray and got a similar reaction and then the same with the gel. Has anyone had this happen? It seems odd to suddenly become allergic to them when I was fine for so long. I was reading about absorption changing and getting a higher dose quickly and it sounds like this could be what was happening. Has anyone been prescribed smaller dose patches to change more frequently? Is this even a thing? Any advice welcome x
