The amount of ibuprofen you can take at once depends on whether it is over- the-counter (OTC) or prescription strength:
- For OTC ibuprofen, the usual dose is 200 to 400 mg taken orally every 4 to 6 hours as needed. You should not take more than 1200 mg in total per day (which is typically up to six 200 mg tablets)
- For prescription-strength ibuprofen, doses can be higher, with a maximum daily dose of up to 3200 mg, divided into 3 or 4 doses per day. The maximum single dose for adults should not exceed 800 mg
- It is generally recommended not to take more than 400 mg at one time if using OTC ibuprofen. Taking 3 tablets of 200 mg (600 mg) at once is not advised as it exceeds the recommended single dose and may increase the risk of side effects
- Ibuprofen doses should be spaced at least 4 to 6 hours apart.
In summary:
- OTC ibuprofen: 200-400 mg per dose, every 4-6 hours, max 1200 mg/day.
- Prescription ibuprofen: up to 800 mg per dose, max 3200 mg/day.
Always take the lowest effective dose for the shortest duration necessary and follow label or doctor's instructions. If unsure or if you have underlying health conditions, consult a healthcare provider before taking ibuprofen.
