Adults can take one or two ibuprofen 200mg tablets (200mg to 400mg) three or four times daily if they need to. You should only take ibuprofen every 4 to 6 hours.

You should not take more than 6 tablets (1200mg) in total in one day if you have bought them over the counter, from a supermarket or drug store. You should always try and take the smallest dose needed that gives you relief.

If your doctor has prescribed them for you on prescription, usually as a higher strength tablet, then you can take a maximum of 3200mg in one day.

How much ibuprofen is in a single dose?

Some prescription strengths of ibuprofen contain an even higher dose, such as 600mg or 800mg. Always check the label on the packet to make sure you know what dosage your ibuprofen tablets contain.
