When patients respond poorly to an antidepressant medication or exhibit intolerable side effects, and switching to another antidepressant is indicated, clinicians should be familiar with the pharmacology of each drug, the potential for drug-drug interactions and discontinuation symptoms, and the time to onset of effectiveness of the new medication.
Switches from one antidepressant to another are common. A study of an administrative claims database found that among patients (n >130,000) who started antidepressant monotherapy for a new episode of depression, switching occurred in 9 percent .
This topic discusses switching from one antidepressant drug to another. Discontinuing antidepressants without switching to another drug and choosing a specific antidepressant regimen for the initial treatment of depression or for treatment resistant depression are discussed separately, as are the pharmacology, administration, and side effects of antidepressants.
