Ibuprofen, the active ingredient in Advil, has not been directly linked to causing depressive symptoms. However, some studies suggest that the use of non-steroidal anti-inflammatory drugs (NSAIDs), which include ibuprofen, might be associated with a higher risk of depression or depression relapse [1].

It is important to note that the relationship between NSAID use and depression is not fully understood and requires further research. Moreover, depression can be caused by a variety of factors, including genetics, brain chemistry imbalances, and life events [2].

If you are concerned about the potential side effects of Advil or any other medication, it is always best to consult with a healthcare professional. They can provide personalized advice based on your medical history and current health status.

In summary, while there is some evidence suggesting a possible link between NSAID use and depression, more research is needed to establish a clear connection. Advil's side effects have not been specifically linked to causing depressive symptoms.
