alt Hacker NewsI don't think I've ever seen half a pill be prescribed, I don't think that exists as a thing in my country. They'd just give you smaller pills?
In fact the opposite happens here, you end up with instructions like "Take ten", each of which has to be individually popped out of a blister pack.
Not every medication is manufactured in the precise doses required. To get to the right amount, a few common doses will be produced with score marks to allow easy(ish) division for a smaller amount. For example, one of my family members has needed a half-pill of thyroid medicine. Something like a 75mcg pill split in half to make it 37.5mcg.
