Advil is a nonsteroidal anti-inflammatory drug (NSAID) that is commonly used to relieve pain, reduce fever, and reduce inflammation [2]. While Advil is generally considered safe when used as directed, there are some potential negative experiences associated with its use.

One of the most common side effects of Advil is stomach upset, including nausea, vomiting, and abdominal pain [2]. This is because Advil can irritate the lining of the stomach, leading to inflammation and discomfort. In rare cases, Advil can also cause more serious gastrointestinal problems, such as bleeding or perforation of the stomach or intestines [2].

Another potential negative experience associated with Advil is an increased risk of heart attack or stroke, particularly in people who already have cardiovascular disease or who have risk factors for it [2]. This is because Advil can increase blood pressure and interfere with the function of blood platelets, which can increase the risk of blood clots.

In addition, Advil can interact with other medications, including blood thinners, antidepressants, and certain types of blood pressure medications [2]. This can lead to potentially dangerous side effects or reduced effectiveness of the medications.

It is important to note that these negative experiences are relatively rare and most people who use Advil do not experience any serious side effects [2]. However, it is important to use Advil as directed and to talk to a healthcare provider before using it if you have any underlying medical conditions or are taking other medications.
