Advil is a brand name for the drug ibuprofen, which is a nonsteroidal anti-inflammatory drug (NSAID) used to treat pain, fever, and inflammation [1]. The maximum safe dose of Advil varies depending on factors such as age, weight, and medical history. According to the FDA, the maximum recommended daily dose of ibuprofen is 1200 mg for adults and 40 mg/kg for children [2]. It is important to follow the instructions on the label or as directed by a healthcare provider.

Taking too much Advil can cause serious side effects, including stomach bleeding, kidney damage, and heart attack [3]. The risk of these side effects increases with higher doses and prolonged use. Therefore, it is important to avoid exceeding the recommended dose and to not take Advil for more than 10 days without consulting a healthcare provider [3].

In conclusion, the maximum safe dose of Advil varies depending on individual factors and should be followed as directed on the label or by a healthcare provider. Exceeding the recommended dose can cause serious side effects and should be avoided [1][2][3].
