Symptoms of depression can also be caused by the use of or withdrawal from alcohol and illegal drugs. Cocaine, amphetamines (methamphetamines, crystal meth, or crack), heroin, and marijuana can all cause symptoms of depression.

If you think that your feelings of depression may be caused by a medicine:

• Call the doctor who prescribed the medicine. Ask if you should stop taking it or take a different one.
• If you are taking a nonprescription medicine, stop taking it. If you feel you need to keep taking it, call your doctor. There might be a different medicine you can take.
