Advil is a brand name for ibuprofen, which is a nonsteroidal anti-inflammatory drug (NSAID) used to treat pain, fever, and inflammation [1]. The recommended dosage of Advil or ibuprofen varies depending on the age, weight, and medical condition of the individual. The maximum recommended daily dose of ibuprofen for adults is 3200 mg per day, which is equivalent to eight tablets of Advil 200 mg [2]. However, it is important to note that taking high doses of ibuprofen for a prolonged period can increase the risk of gastrointestinal bleeding, kidney damage, and cardiovascular events [2]. Therefore, it is recommended to take the lowest effective dose for the shortest duration possible and to consult a healthcare provider before taking any medication [3].
