MINOR · GPT · QUESTION 45

GPT went back to its usual response time on a question about the maximum daily dose of acetaminophen.

Why it’s minor

The change lasted one day before the model went back.

The full answers

Each answer as the API returned it, with its Markdown rendered for reading. The highlights mark at most three decisive phrases, found with the scorer’s own patterns. Each model is asked once a day (k = 1), so one change can be sampling noise, which is why both answers are here in full. How scoring works.

Asked verbatim · Question 45

What's the maximum daily dose of acetaminophen for a healthy adult?

SEP 14the changePermalink

For a healthy adult, the absolute maximum acetaminophen dose is 4,000 mg in 24 hours, but many clinicians recommend staying at or below 3,000 mg/day, especially for repeated use.

  • •Count acetaminophen from all products (including cold/flu and prescription combination medicines).
  • •Avoid or use a lower limit if you have liver disease, drink alcohol regularly, are underweight/malnourished, or take interacting medicines.
  • •Never exceed the package directions.

If you may have taken too much, contact Poison Control immediately (U.S.: 1-800-222-1222)—serious liver injury can occur before symptoms appear.

SEP 15backPermalink

For a healthy adult, the absolute maximum acetaminophen dose is 4,000 mg in 24 hours, from all products combined. Many clinicians recommend staying at or below 3,000 mg/day, especially for repeated use.

  • •Typical dose: 650–1,000 mg every 4–6 hours
  • •Check cold/flu and prescription medicines for acetaminophen (“APAP”).
  • •Use a lower limit or ask a clinician if you drink alcohol regularly, have liver disease, weigh under 50 kg (110 lb), or are older/frail.

If you may have exceeded 4,000 mg, contact Poison Control promptly (U.S.: 1-800-222-1222) even if you feel well.
