Advil is a brand name for the drug ibuprofen, which is a nonsteroidal anti-inflammatory drug (NSAID) used to relieve pain and reduce fever [1]. According to the manufacturer, the recommended dose of Advil is one or two tablets every four to six hours, not to exceed six tablets in 24 hours [3]. However, it is important to note that the frequency and dosage of Advil intake may vary depending on the individual's age, weight, medical condition, and other factors. It is recommended to consult a healthcare provider before taking Advil or any other medication [2]. Additionally, overuse or prolonged use of Advil can lead to adverse effects such as stomach bleeding, kidney damage, and heart attack [2]. Therefore, it is important to follow the recommended dosage and not exceed the maximum daily limit.
