If using 800 mg of ibuprofen in pill form, how long before physical activity should you take it?

Prostaglandins are substances produced in the brain in response to illness or injury which causes pain and swelling and Ibuprofen helps in blocking this substance.

According to experts, it takes 15- 20 min for Ibuprofen to kick in and close to 2 hours to take effect.

It also depends on the form of Ibuprofen, like; if you are taking ibuprofen in liquid form it will take lesser time as the body doesn’t need to break down the capsule/Tablet. It quickly goes to the bloodstream and relieves the pain.

If you are taking it tablet form it might take more time. Always remember to have Ibuprofen after food, else you might throw up.

Usually, to help prevent pain in relation to activity, medication should be taken 30-60 minutes before an activity expected to aggravate pain.
