For adults, the typical recommended dose of 200 mg ibuprofen is 1 or 2 tablets every 4 to 6 hours as needed, but no more than 6 tablets (1200 mg) in 24 hours for over-the-counter use. Taking 3 tablets (600 mg) at once is not recommended as it exceeds the usual maximum single dose of 400 mg. For prescription use under medical supervision, higher doses up to 3200 mg per day may be allowed, but this is not typical for over-the-counter use. Always try to take the lowest effective dose for the shortest time needed and take ibuprofen with food to reduce stomach irritation.
