What quantity of panadol (acetaminophen) would it take to do damage/make someone pass out?

Wrong question 2 ask: But since you're asking, the answer is that it's time for you to seek medical attention for suicidal ideation. Of course, this being the Internet, I have no idea of intention behind your question/post. Perhaps you're asking out of concern for someone else. In which case, you can easily find answer by searching online w/o asking physician. But as a physician, I have to assume worst. Go to ER 4 help
