What Are Warnings and Precautions for Desipramine?
In short-term studies, antidepressants increased the risk of suicidal thinking and behavior in children, adolescents, and young adults (under 24 years) taking antidepressants for major depressive disorders and other psychiatric illnesses. This increase was not seen in patients aged over 24 years. A slight decrease in suicidal thinking was seen in adults over 65 years. In children and young adults, risks must be weighed against the benefits of taking antidepressants. Patients should be monitored closely for changes in behavior, clinical worsening, and suicidal tendencies. This should be done during initial 1-2 months of therapy and dosage adjustments. The patient's family should communicate any abrupt changes in behavior to the healthcare provider.
Worsening behavior and suicidal tendencies that are not part of the presenting symptoms may require discontinuation of therapy.
This drug is not approved for use in pediatric patients.
Keep out of reach of children. In case of overdose, get medical help or contact a Poison Control Center immediately.

- Any drugs or conditions that prolong QT interval

- Starting desipramine in a patient who is being treated with linezolid or intravenous (IV) methylene blue is contraindicated because of an increased risk of serotonin syndrome
- If linezolid or IV methylene blue must be administered, discontinue desipramine immediately and monitor for central nervous system (CNS) toxicity; may resume clomipramine 24 hours after last linezolid or methylene blue dose or after 2 weeks of monitoring, whichever comes first
