Advil is a brand name for ibuprofen, a nonsteroidal anti-inflammatory drug (NSAID) used to treat pain and reduce fever [1]. While Advil is generally considered safe when used as directed, it can cause some side effects [2]. Common Advil side effects include upset stomach, heartburn, nausea, vomiting, headache, dizziness, and drowsiness [3]. These side effects are usually mild and go away on their own after a short time. However, if these side effects persist or worsen, it is important to contact a healthcare provider.

In addition to the common side effects, Advil can cause serious side effects in some people. These include stomach ulcers, bleeding in the stomach or intestines, kidney problems, high blood pressure, heart attack, and stroke [3]. These side effects are more likely to occur in people who take Advil for a long time, at high doses, or who have a history of stomach ulcers, bleeding disorders, kidney disease, or heart disease. It is important to talk to a healthcare provider before taking Advil if you have any of these conditions.

To minimize the risk of side effects, it is important to take Advil as directed. This means taking the lowest effective dose for the shortest amount of time possible. It is also important to avoid taking Advil with alcohol or other medications that can increase the risk of side effects. If you experience any side effects while taking Advil, contact a healthcare provider right away.

In conclusion, Advil can cause both common and serious side effects. While it is generally safe when used as directed, it is important to talk to a healthcare provider before taking Advil if you have any underlying health conditions. If you experience any side effects while taking Advil, contact a healthcare provider right away.
