People age 12 and older can safely take one Advil tablet every four to six hours as long as needed or two tablets every four to six hours if one tablet does not relieve pain or fever, notes Advil. Children under age 12 should only take Advil by doctor’s order.
The dosing instructions are the same for Advil’s tablet, caplet, gel caplet, film-coated and Liqu-Gel products, notes Advil. Each dose of Advil contains 200 milligrams of ibuprofen, a nonsteroidal anti-inflammatory drug, or NSAID.
