Advil is a brand name for the nonsteroidal anti-inflammatory drug (NSAID) ibuprofen [1]. It is used to relieve pain, inflammation, and fever. It is available over-the-counter and in prescription strength. The maximum daily dose of Advil is 1200 mg for adults [2]. However, the maximum daily dose of ibuprofen, regardless of brand, is 3200 mg for adults [3]. It is important to note that the maximum dose should not be taken for more than 10 days, unless directed by a doctor [3]. It is also important to talk to a doctor before taking Advil or any other medication, especially if you have a history of stomach ulcers, kidney or liver disease, or heart problems [3]. Additionally, it is recommended to not take Advil with other NSAIDs or aspirin, as this can increase the risk of side effects [3].
