Question: how long do you have to wait to take another ibuprofen?
Answer: The usual dose for adults is one or two 200mg tablets 3 times a day. In some cases, your doctor may prescribe a higher dose of up to 600mg to take 4 times a day if needed. This should only happen under supervision of a doctor. If you take ibuprofen 3 times a day, leave at least 6 hours between doses.
