What happens if you take 10 paracetamol?

If you mean 10mg of Hydrocodone, you've regulated severe pain. If you mean 10 tablets that contain hydrocodone, the three questions you need answers to are:

1. How much hydrocodone per tablet/capsule?
2. What else is in that capsule?
3. And how much of the other stuff is there as well?

Hydrocodone is rarely administered by itself. Most often, you see it mixed with APAP (Acetaminophen), a NSAID with potentially severe side effects that damage the liver in chronic or acute overdose.

Consider re-asking this question with more information.
