According to the makers of Advil, none of the varieties of the pill contain caffeine. The active ingredient in Advil is ibuprofen, which can be used to lessen fevers, reduce inflammation and relieve pain.
Each Advil tablet or capsule contains 200 milligrams of ibuprofen. Inactive ingredients found in the pill include white wax, corn starch, sodium benzoate, stearic acid and synthetic iron oxide. The inactive ingredients help preserve the pill and give it a longer shelf life. They do not have a physical effect on the person taking the medication except to mask pain. Advil should be taken as directed on the packaging or by a doctor to decrease the chance of a stomach bleed occurring.
