Overview

The following warning signs may be present in adults who have a high risk for suicide:

• Depression or other mental health condition, such as severe anxiety, bipolar disorder (manic-depressive illness), or schizophrenia
• Depression followed by sudden cheerfulness and contentment, which may mean the person has made a decision to finalize a suicide plan
• A previous suicide attempt
• Substance use disorder
• Preoccupation with death in conversations
• Giving away personal possessions

Factors that may increase the risk of suicide include having:

• A family member who has died by suicide.
• A family history of depression, bipolar disorder, or schizophrenia.
• A history of physical or sexual abuse.
• Diagnosis of a serious medical illness.
• Failing relationships.
• A divorce.
• A recent life change, such as a death of a spouse or other member of the family, marriage, break-up of a marriage, the birth of a child, a job loss, a job promotion or demotion, or legal problems.

Health Canada and the U.S. Food and Drug Administration (FDA) have issued advisories on antidepressant medicines and the risk of suicide. Talk to your doctor about these possible side effects and the warning signs of suicide.
