Pharmacist intervention to detect drug adverse events on admission to the emergency department: Two case reports of neuroleptic malignant syndrome.

WHAT IS KNOWN AND

OBJECTIVE

Neuroleptic malignant syndrome (NMS) is a rare but severe adverse effect of antipsychotic drugs.

CASE DESCRIPTION: We report two cases of NMS highlighted by clinical pharmacists in an emergency unit during summer. One of them was fatal. Medication reconciliation processes performed at admission identified treatment with loxapine for one of them and with loxapine and clozapine for the other. Interview of the patients highlighted clinical symptoms suggesting NMS, allowing the pharmacists to alert the medical team.

WHAT IS NEW AND

CONCLUSION

Adverse drug events may be severe and clinical pharmacists in emergency departments can help to detect them.
