Advil is a brand name for the drug ibuprofen, which is a nonsteroidal anti-inflammatory drug (NSAID) used to relieve pain, fever, and inflammation [1]. While Advil is generally considered safe when used as directed, there are some risks associated with its use.

One of the most common side effects of Advil is gastrointestinal irritation, which can cause stomach pain, nausea, and heartburn [2]. In some cases, Advil can also cause more serious gastrointestinal problems, such as bleeding or perforation of the stomach or intestines [1]. This risk is higher in people who have a history of stomach ulcers or bleeding, as well as in older adults [2].

Advil can also increase the risk of cardiovascular events, such as heart attack or stroke, especially when used at high doses or for long periods of time [1]. This risk is higher in people who have a history of heart disease or stroke, as well as in older adults [2].

Other potential side effects of Advil include allergic reactions, kidney problems, and liver damage [3]. It is important to use Advil only as directed, and to talk to a doctor before using it if you have any underlying medical conditions or are taking other medications.

In summary, while Advil is generally considered safe when used as directed, there are some risks associated with its use, including gastrointestinal irritation, cardiovascular events, and other potential side effects. It is important to use Advil only as directed and to talk to a doctor before using it if you have any underlying medical conditions or are taking other medications.
