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 doesnât 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.
That said, you can always take more otc ibuprofen to achieve exactly the same effect. posted by jessamyn at 5:25 PM on October 26, 2009 [1 favorite] Googling for shelf life ibuprofen turned up a bunch of hits claiming anywhere from 2 - 5 years, most saying 2 - 3 years from the date of manufacture. Assuming it's been stored cool, dark and dry, that sounds pretty reasonable to me.
