It may do, it may not. Ive always wondered why, given the guidelines around paracetamol, you can pick it up in supermarkets, any pharmacy etc.
Yet we know the damage done by overuse, misuse and overdose, similar with other pain killing drugs.
No central pharmacy register where you have to give your details and provide ID for strong painkillers, thats not difficult to bring in (albeit costly)
So things are only made 'stricter' under some circumstances, not others, a lot of it is political, with a big P and a little p. Some of it is about optics. Some of it is about licencing.
But as Ive already said, the way around this, as best we can, is to have it prescribed easily by your GP, no hoops to jump through like a 4 year long waiting on a 'weight loss programme'. If you're fat and have no contra indications and the side effects are not counter productive, then you should have it.
