In the past two and a half years (January 2014 through June 2016, inclusive), the NHS in England supplied 10,863 prescription items of desiccated thyroid with a total cost of £1,422,405.84. (Probably each item is one pot of tablets. So for someone getting 60mg plus 30mg that would be counted as two items.)
The brands/manufacturers mentioned include Armour, Nature-Throid, Erfa, WP Thyroid – though some are only identified by thyroid hormone content.
