They are widely sold at 1000 mg (1g) tablets in Europe, but in many countries they require doctor's prescription. There are also purchase limits to the number of pills you can buy at once.

The .nl indicates the netherlands. Many people in the netherlands vent/joke about how the doctors here only ever tell you to take paracetamol and come back in two weeks if it's still a problem (recursive solution).

However the last time I went to my GP she scoffed at me taking the maximum and suggested I take literally double the maximum recommended dose 4-5 times a day which totaled I think 2.5x the daily maximum on the package. I am very much a "believer" in science and reasonable medical authority but this experience sowed the seeds of doubt, because from what I have always heard, that can actually kill you or cause permanent liver issues. I was also taking diclofenac simultaenously, and when I told her how many mg, she asked "where can you even buy such small doses, that's what I would give a small child" =/

They are common in France, but not in such packages: There are restrictions that prevent you from buying more than than 8g/day (theoretically at least, I don't believe they are strictly applied in practice).

The linked size is also quite common in Belgium.

In Europe for sure they're also sold in 1g dosing. I think the packages don't contain lots of pills, though. Definitely not US style buckets of pills.
