You may have an increased risk of suicidal thoughts or behavior at the start of treatment with an antidepressant medication, especially if you are 18 years of age or younger. Talk with your doctor about this risk. While you are taking this medication you will need to be monitored for worsening symptoms of depression and/ or suicidal thoughts during the first weeks of treatment, or whenever your dose is changed.
