Sounds a bit odd to me?
I can't see anything on the web about it, so even if it was discontinued today, there would be sufficient stocks of it to last for a few weeks anyway. Maybe there is a temporary shortage though - sometimes that does happen with some products. Even so another pharmacy might have it in stock?
I would go to a different pharmacist or go back to the same one saying as far as you know it hasn't! Alternatively phone your practice and see what they say - but I've googled and nothing comes up.
