The MHRA has available a considerable number of Public Assessment Reports on medicines. These reports seem to be written during licence application processes.
Unlike the Electronic Medicines Compendium (EMC), which is obviously intended for broad public access, these documents are almost hidden away. Looks as if the only way of finding them is by the very simple search process on this page:
Ironically, when you type “levothyroxine” the search finds all the medicines which interfere with levothyroxine such as ferrous sulphate, as well as the most recent liquid and Teva tablet levothyroxine products.
(Some might be findable by other search engines – but they don’t appear near the top of most searches!)
It is a lucky-dip – you might or might not find any specific medicine you search for. Hopefully it will become more complete in time, but maybe it won’t?
