Used primarily as an antidepressant, it functions as a monoamine oxidase inhibitor (MAOI), effectively increasing the levels of certain chemicals in the brain to improve mood and emotional stability. It is often prescribed for patients who have not responded to other types of antidepressant medications. Additionally, it has been explored for its potential in treating conditions like social anxiety disorder and panic disorder. Its application requires careful monitoring due to potential interactions with certain foods and medications, which can lead to serious side effects.
