Avoiding alcohol, narcotics, sedatives that have not been prescribed, and illegal drugs can help prevent suicide. These substances affect the brain and can make the depression worse over time.

In homes with adolescents:

• All prescription medicines should be kept secure.
• Do not keep alcohol in the home, or keep it locked up.
• Securely lock all guns and keep the ammunition separate.

Many people who attempt suicide talk about it before making the attempt. Sometimes, simply talking to a sympathetic, nonjudgmental listener is enough to prevent the person from attempting suicide. For this reason suicide prevention centers have telephone "hotline" services. Again, do not ignore a suicide threat or attempted suicide.

As with any other type of emergency, it is best to immediately call the local emergency number (such as 911). Do not leave the person alone even after phone contact with an appropriate professional has been made.
