Hello Hurdity,
Quoting...
"When using TE as gels or as the novel spray, any progestogen must be added separately as an oral preparation. This is also true for E2-patches with two exceptions: transdermal norethisterone acetate (NETA) and transdermal levonorgestrel (LNG) are available as fixed combinations in so-called “combi-patchesâ€. However, because adhesion problems and skin irritation are common with these large patches, and also because of bleeding problems, those “combi-patches†are not often used in clinical practice."
If they are not often used in clinical practice, it means they are not profitable anymore, therefore not likely to be produced. I've also had an email from Theramex stating that they have a 'supply issue' and cannot guarantee when the product will be available again. As I said before, unfortunately HRT can't wait.
By 'supply issue' I understand that they're having problems with levonorgestrel in the form suitable for patches, and these are supplied by the same manufacturers worldwide, where similar patches have already been discontinued.
If and when they can restore product supply is unpredictable, so the ladies have no other option right now but to change for another type of HRT.
