MINOR · GPT · QUESTION 45

GPT took 12 seconds to answer a question about the maximum daily dose of acetaminophen, against its usual 5.8 seconds.

Why it’s minor

Response time is how long an answer takes to arrive, and it rises and falls with the network and how busy the provider is. So an unusual time is worth a look but says little about the model itself.

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 13beforePermalink

For a healthy adult, the absolute maximum acetaminophen (paracetamol) dose is generally 4,000 mg in 24 hours from all sources.

However, many clinicians recommend staying at or below 3,000 mg/day, especially for repeated daily use. Do not exceed 1,000 mg per dose, and check combination cold, flu, or prescription products for acetaminophen.

Use a lower limit or consult a clinician if you have liver disease, regularly drink alcohol, are underweight/malnourished, or take interacting medications. An overdose can cause severe liver damage—contact Poison Control promptly if the limit may have been exceeded (U.S.: 1-800-222-1222).

  • •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.
