Clomipramine-induced pancytopenia.
The Journal of Nervous and Mental Disease

Summary
Clomipramine, a medication for depression, can cause pancytopenia, a condition of low blood cell counts. Stopping the drug led to a recovery of blood cell levels in a patient.
Area of Science:
- Pharmacology
- Hematology
- Psychiatry
Background:
- Major depressive disorder with psychotic features is a severe mental health condition.
- Clomipramine is a tricyclic antidepressant used in treating depression and obsessive-compulsive disorder.
- Drug-induced hematological abnormalities are a known, though infrequent, complication of pharmacotherapy.
Observation:
- A 54-year-old male patient was prescribed clomipramine for a major depressive episode with psychotic features.
- The patient subsequently developed pancytopenia, characterized by a significant reduction in all three major blood cell lines (red blood cells, white blood cells, and platelets).
Findings:
- Discontinuation of clomipramine therapy resulted in a marked improvement in the patient's hematological parameters.
- This suggests a direct causal link between clomipramine use and the development of pancytopenia in this individual.
Implications:
- This case highlights the potential for clomipramine to induce severe hematotoxicity, including pancytopenia.
- Clinicians should maintain a high index of suspicion for drug-induced blood dyscrasias when patients on clomipramine present with cytopenias.
- Monitoring complete blood counts in patients receiving clomipramine, especially those with risk factors, may be warranted.
