Hi just posted on a different thread but today I got 3 months supply of Estradot, 3 boxes of 100 and 3 boxes of 25s. May be worth trying any chemists in your area as you could ask for your prescription to be sent to anyone who has stock. Just be aware, if they can only give you a part prescription, you can only get any remainder from the same chemist. ( i.e you need 3 boxes of 50s and they only have one in stock at that time, you must wait for them to get the next 2 in stock, you will not be able to get the remainder elsewhere)
Also, my own pharmacy has been very helpful and at some time they amended my prescriptions, as I need 125, the 100 and 25s were hard to get. I had 2 old boxes of 50s at home and they allowed me to have 2 new boxes of 75s to make up the correct strength) maybe yours Will help you out that way?
