Antidepressants can have troubling side effects and are addictive for some people.

Psychotherapy works, and some types of therapy have been shown to be much more effective than antidepressants over the long run.

There are a variety of techniques to help people change the kind of thinking that leads them to become depressed. These techniques are called cognitive behavioral therapy.

Depression is a serious problem, but drugs are not the answer. In the long run, psychotherapy is both cheaper and more effective, even for very serious levels of depression. Physical exercise and self-help books based on CBT can also be useful, either alone or in combination with therapy. Reducing social and economic inequality would also reduce the incidence of depression.

Depression comes back over time in about 90 percent of people on antidepressants. Studies show that relapses are far less common when people are treated with psychotherapy.
