I've just spent an hour on the phone trying to track down Colestytramine light but no luck. The NHS reported on this potential shortage last year: sps.nhs.uk/articles/shortag...
They state "Colestyramine light 4g sachets – Mylan – (recently launched) available in wholesalers from week commencing 10 February 2020". However, it is now April and no one seems to have it.
Any ideas on where to get this product?
