Pharmacologic management of adult depression.

Major depression is a common and treatable disease. Many patients benefit from pharmacologic treatment and, because there is little variation in antidepressant effectiveness, medication choices should be made based on patient characteristics, safety, and anticipated side effects. Most patients respond favorably to treatment, but many do not have complete symptom relief. Changing medications or augmenting with a second medication is helpful for some partial or nonresponders. All antidepressants are capable of producing harmful side effects, and some are particularly prone to dangerous drug-drug interactions. The risk of suicide is always a concern in depression and this risk is not necessarily reduced by the use of antidepressants. Some persons may have an increase in suicidal thoughts with antidepressant treatment. Close follow-up is required when initiating therapy and adjusting dosages.
