Most antidepressants are generally safe, but the U.S. Food and Drug Administration (FDA) requires that all antidepressants carry black box warnings, the strictest warnings for prescriptions. In some cases, children, teenagers and young adults under 25 may have an increase in suicidal thoughts or behavior when taking antidepressants, especially in the first few weeks after starting or when the dose is changed.
Anyone taking an antidepressant should be watched closely for worsening depression or unusual behavior. If you or someone you know has suicidal thoughts when taking an antidepressant, immediately contact your health care provider or get emergency help.
Keep in mind that antidepressants are more likely to reduce suicide risk in the long run by improving mood.
