Hi there. Has anyone come across a shortage of MTX manufactured by Mercury Pharma? I went to Boots yesterday with my prescription and when I got home the tablets looked completely different - tiny little pills and made by Tiva. I've never had anything other than the Mercury Pharma ones (blister pack, while & purple box) and panicked. I took them back and didn't quite believe the story about being out of supply, so I drove round or phoned up every chemist for miles around and it's true. There is a production issue at the suppliers which won't be rectified until mid Feb, although some chemists think it will be longer. I managed to get 21 tablets and an IOU from another branch of Boots, but am warned that when these run out in 3 weeks I will have to take whatever they've got. Am I being over cautious? I seem to remember reading somewhere that you should try to stick to the same brand. Angela.
