Objective:

To report a case of acute pulmonary embolism (PE) occurring within hours of initiating antipsychotic therapy in a patient without known risk factors for venous thromboembolism (VTE), highlighting the rarity of such rapid onset.

Key Findings:
  • The patient developed PE within hours of starting antipsychotic therapy, highlighting a rare rapid onset of VTE.
  • No predisposing risk factors for VTE were identified in the patient.
Interpretation:

This case emphasizes the need for heightened clinical vigilance for VTE in patients starting antipsychotic therapy, even in the absence of traditional risk factors.

Limitations:
  • The case is a single report and may not be generalizable to all patients receiving antipsychotic therapy.
  • Limited data on the biological mechanisms linking antipsychotic use and VTE.
Conclusion:

Clinicians should be aware of the potential for rapid onset of PE in patients receiving antipsychotic medications, necessitating early assessment and intervention.
