Thank you all for your comments. We went to B....s, immediately after DH appointment. Saw the young girl who said she would prepare my prescription yesterday. No apologies, she just said, “I’ll get that changed for you”.
Anxiousgran, luckily I had enough pills to last until tonight, but if I had used the ‘wrong’ ones, for two weeks, I would have had to request another prescription, and wait for it to be dispensed. I also think my Dr would have wondered why I needed more, when he had prescribed the correct amount, in the correct dosage, in the first place.
All is now resolved, but it will make me more alert, and check what is given to me, and not take for granted that the chemist is right.
