The hot patient: acute drug-induced hyperthermia

Drugs can cause dysregulation of the hypothalamic–pituitary–adrenal axis which can result in a rise in core temperature. This type of hyperthermia is unresponsive to antipyretics and can be complicated by rhabdomyolysis, multi-organ failure and disseminated intravascular coagulation. Organic causes...

Description
Summary:Drugs can cause dysregulation of the hypothalamic–pituitary–adrenal axis which can result in a rise in core temperature. This type of hyperthermia is unresponsive to antipyretics and can be complicated by rhabdomyolysis, multi-organ failure and disseminated intravascular coagulation. Organic causes of fever such as infection must be ruled out. Syndromes associated with drug-induced fever include neuroleptic malignant syndrome and anticholinergic, sympathomimetic and serotonin toxicity. The class of offending drugs, as well as the temporal relationship to starting or stopping them, assists in differentiating between neuroleptic malignant syndrome and serotonin toxicity. Immediate inpatient management is needed. The mainstay of management is stopping the drug, and supportive care often in the intensive care unit.
