If the Utrogestan's only repackaged for sale in a non EU country it's probably the same contents, do they look the same?
I use Oestrogel now. I was getting Estradot50 with no problems at all until 2 or 3 months ago, but it didn't work for me.
I don't know if it's one of the Brexit requirements that everything goes into new packs, a lot of food is labelled and packed differently but is supposed to be the same inside.
I'd not heard of GB dropping it's standards for medicines yet, but most of the current medical/veterinary problems stem from their abject refusal to use the current EU standards as a common minimum standard, so it's pretty obvious what comes next.
I found the new Oestrogel to work as well as the old one, but my dose went up to three pumps same time the bottle changed, so maybe that was why?
