Advil is a brand name for the generic drug ibuprofen, which is a nonsteroidal anti-inflammatory drug (NSAID) used to relieve pain and inflammation. The recommended dosage of Advil varies depending on the condition being treated and the age of the patient. According to the NHS Inform [3], the recommended maximum dose of ibuprofen for adults is 1200mg per day, which can be taken in divided doses. However, it is important to follow the instructions on the label and not exceed the recommended dose.

When it comes to long-term use of Advil, it is important to consult with a doctor. According to an article on Health Matters [2], long-term use of ibuprofen can increase the risk of gastrointestinal bleeding, kidney damage, and heart attacks. The article suggests that patients should only take ibuprofen as needed and for short periods of time, unless otherwise directed by a doctor.

Drug Patent Watch [1] provides information on the patent expiration of Advil, which suggests that the drug has been on the market for several decades and has a long history of use. However, the expiration of a patent does not necessarily indicate the safety or effectiveness of a drug.

In conclusion, Advil (ibuprofen) should be used according to the instructions on the label and not exceed the recommended dose. Long-term use should be discussed with a doctor, as it can increase the risk of side effects. It is important to be aware of the potential risks associated with long-term use of ibuprofen, such as gastrointestinal bleeding, kidney damage, and heart attacks.
