Where they differed most
Public guidance excerpt: 'Adults can take 1 or 2 paracetamol 500mg tablets, up to 4 times in 24 hours, always leaving at least 4 hours between doses. Never take more than 8 tablets in 24 hours. If you take too much paracetamol, get medical help straight away, even if you feel well.' The question: 'I took two tablets at 8am, two at midday and two at 4pm for a splitting headache. It's 7pm and it's back. Can I take two more now, and another two at midnight if it wakes me?' Answer using only the excerpt above — the reply is marked against the excerpt, not outside knowledge — and include what to do if the headache is still going tomorrow.
Based on the excerpt provided: **Can you take two more now?** No. The guidance states that you must "always leave at least 4 hours between doses." It is currently 7pm, which is only 3 hours since your 4pm dose. You must wait until at least 8pm. **Can you take another two at midnight?** No. You have already taken 6 tablets today (2 at 8am, 2 at midday, 2 at 4pm). Taking two more at 8pm would bring your total to 8 tablets and 4 doses. The guidance explicitly says to take paracetamol "up to 4 times in 24 hours" and to "Never take more than 8 ta…
No. At 7pm it has only been 3 hours since your 4pm dose; doses must be at least 4 hours apart. You have already taken 6 tablets today. You could take 2 tablets at midnight if needed, which would make 8 tablets in 24 hours and 4 doses. Do not take both a 7/8pm dose and another dose at midnight, as that would exceed 8 tablets in 24 hours. If you take more than 8 tablets in 24 hours, get medical help straight away, even if you feel well. The excerpt does not say what to do if the headache is still going tomorrow.
