Just a little note that may help someone. This is official...your GP CAN supply NDT on a green NHS Prescription, my new GP has done this for me and I am over the moon! Anyway for those of you brave enough to ask your GP here is a little information that may help your cause, UL Medicines Ltd (01923 204333) have given this price for WP Thyroid: £55.18 per 100 (1 grain) this is to your chosen chemist as they do not deal with the public, the prescription must state that this is for Hypothyroidism. So if your GP says its too expensive you can give him/her these details! Good luck - and don't give up!
