After reviewing the available information, there is no direct link presented between Advil and a worsened antidepressant response. It's important to note that Advil is a brand name for ibuprofen, an over-the-counter nonsteroidal anti-inflammatory drug (NSAID) used to treat pain, fever, and inflammation [1].

The sources provided discuss antidepressants and alcohol [2] and medications for dementia [3], but there is no mention of Advil or ibuprofen in relation to antidepressants.

However, it's worth noting that NSAIDs like Advil can have interactions with other medications. The Mayo Clinic advises that "if you're taking antidepressants, you might need to avoid or limit taking NSAIDs" due to the risk of bleeding and other complications [2].

In conclusion, while there is no direct link between Advil and a worsened antidepressant response, it's always important to consult with a healthcare provider or pharmacist before combining medications, including over-the-counter drugs like Advil, with antidepressants or any other prescription medications.
