I am in the south of England and it's regularly on the high 20s/low 30s every day just now and I cannot get my Evorel HRT patches to stay on at all. I am going through one a day instead of 2 a week!
I am putting them on dry skin that's as cool as possible first thing in the morning but later on in the day they just peel straight off.
I am giving silicone dressing tape a go to see if that will keep it on. Fingers crossed... Any other suggestions?
