It’s disgusting , I had similar thing done to me but mine were azathrioprine but my tabs were 6 months out of date, I was given them from a well known high street pharmacy, they had actually got them in from a smaller chemist few miles away as my dosage had been lowered by my GP and they didn’t have any lower dose ones, so that was 2 pharmacy’s not doing the job correctly, mine also were initialled twice, I asked to see the book as apparently they sign in a book too when they order in, I was really angry, and complained there and then and also made official complaint, I did hear from their superiors who did apologise, but since I’ve told several people I’ve heard two more cases of it happening same pharmacy, I always check dates now and would advise others also to do this! So glad you noticed yours grandmajan, hope you feel better soon too
