Random non sticky patch in the box - is it a dud?

[Theothername]

I’ve recently switched from divigel to the estradot patch. First 4 have been fine - sticking easily, leaving a bit of residue but that’s ok. This morning’s one isn’t sticky at all. I’ve stuck it down with a plaster but now I’m wondering if it’s a dud and I don’t want to risk going 3 days without oestrogen.

Any experience?

I had 2 unstick evorel patches in my last batch. I just binned and used another. I reordered early and advised gp of the duds. I don't pay for prescriptions though, if I did I'd probably get pharmacy to replace.

I had some Estradot patches like this. I reported it via the yellow card scheme.
