Background
- Also known as drug-induced hyperthermia
- An adverse reaction to a drug in which the recipient of the drug develops a fever
- Most common classes associated with drug fever are antimicrobials, anticonvulsants, antidysrhythmics, and other cardiac agents[1]
Pathophysiology
There are multiple mechanisms by which a drug can directly cause a fever response. These mechanisms include inducing a hyper-metabolic state, direct tissue damage and tissue necrosis, interference with peripheral vasodilation, activation of the cellular or humoral immune responses, or by acting as an endogenous pyrogen. [2]
Clinical Features
- Can occur at any point during therapy but most often occurs 7-10 days after initiation of drug[3]
- May appear "inappropriately well" for the degree of fever
