Advil is a brand name for the drug ibuprofen, which is a nonsteroidal anti-inflammatory drug (NSAID) used to treat pain, fever, and inflammation. Like any medication, Advil has potential risks and side effects that users should be aware of.

According to Drug Patent Watch [1], the most common side effects of Advil are stomach pain, nausea, and indigestion. These side effects are usually mild and go away on their own, but they can be more severe in some people. Other potential side effects of Advil include headache, dizziness, drowsiness, and allergic reactions.

GoodRx [2] lists additional potential side effects of Advil, including increased risk of heart attack or stroke, gastrointestinal bleeding, kidney damage, and liver damage. These side effects are more serious and less common than the mild side effects mentioned above, but they can still occur.

The Mayo Clinic [3] also warns that Advil can interact with other medications, including blood thinners, antidepressants, and steroids. People who have certain medical conditions, such as asthma, high blood pressure, or kidney disease, may be at higher risk of experiencing side effects from Advil.

In summary, while Advil can be an effective medication for treating pain, fever, and inflammation, it is important to be aware of the potential risks and side effects. Users should always follow the recommended dosage and talk to their doctor if they have any concerns or experience any unusual symptoms.
