Neuroleptic malignant syndrome is a life-threatening reaction that
occurs from taking antipsychotic medications. The exact cause of this syndrome
is not known. However, it may occur when antipsychotic medications cause a
person's body temperature regulating center to function improperly.
The first signs of neuroleptic malignant syndrome include:
- High fever, between
102
°F (38.89
°C) and
103
°F (39.44
°C).
- Fast and/or irregular heartbeat.
- Rapid
breathing.
- Severe sweating.
If treatment is not sought, more severe symptoms develop and
include:
- Tight and inflexible muscles.
- Changes
in alertness.
- Blood pressure changes (either lower or higher than
normal).
- Shakiness.
- Seizures.
People with neuroleptic malignant syndrome who do not get treatment
can die from complications of the syndrome. Complications include absence of
breathing, kidney failure, and life-threatening body fluid and chemical
imbalances.
Sometimes people who have a fever and changes in their heart and
breathing patterns think they have the flu. People who take antipsychotic
medications and develop these symptoms need to be seen by a health
professional.
