It contains the active ingredient ibuprofen, which is a pain reliever and fever reducer. Advil is commonly used to treat mild to moderate pain, such as headaches, toothaches, menstrual cramps, and muscle aches [2].

It is important to note that Advil is not recommended for everyone. It should not be used by people who have a history of stomach ulcers, bleeding disorders, or kidney problems. Additionally, it should not be used in children under the age of six months without first consulting a doctor [2].

In summary, Advil is a type of NSAID that is used to alleviate mild to moderate pain, including headaches, toothaches, menstrual cramps, and muscle aches. It is also effective in reducing pain and inflammation associated with arthritis. However, it is important to use Advil as directed and to consult a doctor before using it if you have any underlying health conditions or are taking other medications [2][3].
