Just a bit of info for you all if you do not already know. I have just contacted the pharmacies from Thyroid UK website:
Tollesbury seems to be the most expensive, they do not have 0.5 grains available. The cost = 1 grain £100 for 100 tablets.
Springfield Pharmacy: WP Throid 0.5 grains is £71.50 for 100 tablets. Springfield have Nature-Throid 0.5. grains ,a bit cheaper at £40 for 100 tablets.
Alium pharmacy have Nature Throid 0.5 grains at £25 for 100 tablets.
Health X change Pharmacy have Nature Throid 0.5 grains at £39.00
I am on a 3 week trial without any meds, my endo says he will give me a prescription when I see him in three weeks. However, I have ordered some WP without prescription from the U.S. I may look into Nature-Throid from the U.K when I have used the WP (3 bottles of 100) as it is much cheaper, but if WP suits me I will stick with it.
(I paid around £46 for 0.5 grains, bottle of 100 from U.S)
I hope this is useful.
