Go to: Wikipedia-Malignant Neuroleptic Syndrome for more information.

• MNS is an adverse reaction to neuroleptic or antipsychotic drugs characterized by F E V E R:
  • F =Temp>38
  • E=Encephalopathy
  • V=Vitals signs are unstable
  • E =Elevated CPKs
  • R=Rigidity muscles

Drugs such as Haldol, Chlorpromazine, Metoclopramides, Lithium,and antiparkinson drugs Levodopa can cause MNS.

If MNS is coded, don't also code Accidental toxicity-other drugs as this would be redundant as it would not give us any additional data.
