Neuroleptic malignant syndrome after haloperidol therapy

Area of Science:

• Neuroscience
• Pharmacology
• Critical Care Medicine

Background:

• Neuroleptic Malignant Syndrome (NMS) is a rare but serious adverse reaction to antipsychotic medications.
• Haloperidol, a typical antipsychotic, is known to be associated with NMS.
• Prompt recognition and management are crucial for patient outcomes.

Observation:

• A patient developed NMS following haloperidol administration.
• The patient exhibited unusual and severe complications including cardiac arrhythmia, cardiac arrest, prolonged dysphagia, aspiration pneumonia, seizures, and myoclonus.
• These life-threatening complications presented a significant clinical challenge.

Findings:

• The case highlights the potential for severe and varied complications associated with NMS.
• Despite the severity, the patient's symptoms, including dysphagia and neurological disturbances, resolved over time.
• Aggressive supportive care was instrumental in managing the acute phase.

Implications:

• This report underscores the importance of vigilance for NMS in patients treated with haloperidol.
• It emphasizes the need for comprehensive management strategies to address diverse and severe complications.
• Long-term follow-up is essential to confirm full recovery from NMS and its sequelae.
