The main medical treatment for depression is antidepressant medication.
If you're experiencing moderate to severe depression your doctor may prescribe antidepressant medication, along with psychological treatments. Antidepressants are sometimes prescribed when other treatments have not been successful or when psychological treatments aren't possible due to the severity of the condition or a lack of access to the treatment.
People with more severe forms of depression (bipolar disorder and psychosis) generally need to be treated with medication. This may include one or a combination of mood stabilisers, anti-psychotic drugs and antidepressants.
