The maximum amount of ibuprofen you can take in one day depends on whether it is over-the-counter (OTC) or prescription strength:
- For over-the-counter ibuprofen, adults should not exceed 1200 mg per day , typically taken as 200 to 400 mg every 4 to 6 hours as needed, with a maximum of 6 tablets of 200 mg each per day
- For prescription-strength ibuprofen, the maximum daily dose can be up to 3200 mg per day , divided into 3 or 4 doses throughout the day. The dose per intake can be 400 mg, 600 mg, or 800 mg depending on the prescription, but single doses should not exceed 800 mg
General guidelines for adults are:
- Take 200 to 400 mg every 4 to 6 hours as needed for pain or fever.
- Do not exceed 1200 mg daily if using OTC ibuprofen.
- If prescribed, doses up to 3200 mg daily may be used under medical supervision.
- Avoid taking more than 800 mg in a single dose even if the total daily dose is within limits.
- Use the lowest effective dose for the shortest duration necessary to reduce risk of side effects
Taking more than the recommended maximum dose can lead to serious side effects such as stomach ulcers, gastrointestinal bleeding, kidney damage, dizziness, and in severe cases, seizures or metabolic acidosis. If an overdose is suspected, seek medical attention immediately
. In summary, for most adults using OTC ibuprofen, the safe limit is up to 1200 mg per day, while prescription doses can go up to 3200 mg per day under doctor supervision. Always follow the dosing instructions on the package or from your healthcare provider.
