If I ever had to say anything about Paracetamol, it would be:

Remember: Paracetamol is hepatotoxic, very strong for your liver. Never take it if you have been drinking alcohol or have a weak/damaged liver. Paracetamol is the worst thing you can have for hungover: it might reduce your headache but will hurt a liver that it's already under pressure by the alcohol you drank last night.

In moderation, as prescribed, shouldn't be bad. I'm more of an ibuprofen guy though (although I rarely take it).
