Last year several children died because there was a shortage of basic antibiotics.
Urgh that's awful. I Googled this and it does appear to have been a problem at some point in 2022:
And earlier this year mentioning global supply chain issues that, as you said, are made worse for us with Brexit:
So I stand corrected.
I had a jaunt to hospital last year that involved them trying 3 antibiotics before finding one that did the trick, and a close friend recently had 12 weeks of IV antibiotics for a gnarly spinal infection. A few people in my social group have needed them recently, including amoxicillin which is mentioned in the article linked above, and haven't had an issue getting it. So fingers crossed, its resolved.
I'm sorry you've had to go through such a faff getting your own meds, that's really annoying. I dunno if you've tried Lloyds Direct but its convenient and I've never had delays with them, nor have my ageing parents who need quite a few prescriptions now. Might be worth a shot?
Mea culpa KF I went based on my own experiences without fact checking myself first.
