Hi there
Which country are you in? There has been problems in many countries, Estalis been in short supply in Australia for over a year but has now resolved (for the time being!). They kept saying it was a manufacturing problem, the chemist would get a few boxes in and then nothing for a couple of months.
Whilst it was in short supply the chemist said to me he had a lot of unhappy meno ladies at his door! Then of course there was a shortage of all the other oestrogen patches and some pills.
It's a bit off when there isn't an alternative, we only have the one combined one here. Patches are better for your health so it's doubly annoying that then they are making you take a pill which has to go through your liver...
Maybe call the manufacturer and give them an earful?
The other alternative is do go to one of the online chemists (Canada?) where you have a phone consult with a doc and then they do the prescription for you and mail from their mega pharmacies.
