Advil is a brand name for ibuprofen, a nonsteroidal anti-inflammatory drug (NSAID) used to treat pain, fever, and inflammation [1]. According to the manufacturer's website, Advil can be taken every 4 to 6 hours as needed, but no more than six tablets should be taken in 24 hours [3]. However, it is essential to follow the instructions on the label or as directed by a healthcare provider. Taking more than the recommended dose can lead to serious side effects such as stomach bleeding, kidney damage, and heart attack, especially if taken for an extended period [2].

Additionally, it is important to note that Advil can interact with other medications and medical conditions, such as high blood pressure, heart disease, and asthma. It is crucial to consult with a healthcare provider before taking Advil if you have any underlying medical conditions or are taking other medications [2].

In conclusion, taking multiple Advil tablets can be safe if taken as directed and not exceeding the recommended dose. However, it is crucial to follow the label instructions and consult with a healthcare provider if you have any underlying medical conditions or are taking other medications [3].
