R50.2

Clinical Causes: Use of antibiotics, such as penicillins, sulfonamides, and cephalosporins Anti-inflammatory medications like aspirin and NSAIDs Anticonvulsants including phenytoin and carbamazepine Chemotherapy drugs Histamine H2 receptor antagonists Other medications, including certain antidepressants and antihistamines

Key Symptoms: Elevated body temperature (fever) Chills and sweating Rash or skin reactions in some cases Muscle aches or malaise Sometimes leukocytosis (increased white blood cells)

Diagnosis Path: Diagnosing drug-induced fever involves a thorough medical history, including recent medication use, and a physical examination. Healthcare providers often perform laboratory tests such as blood counts, blood cultures, and other relevant diagnostics to rule out infections and other causes of fever. Discontinuation of the suspected medication usually results in the resolution of the fever, which supports the diagnosis. In some cases, a re-challenge with the drug may be considered under close medical supervision to confirm causality.

Treatment Protocols: The primary step in managing drug-induced fever is to identify and stop the offending medication. Symptomatic relief may include the use of antipyretics like acetaminophen to reduce fever. Monitoring the patient’s temperature and overall condition is crucial. In cases where the reaction is severe or involves additional symptoms, healthcare providers may need to administer supportive treatments or medications to manage allergic reactions or complications. Once the causative drug is discontinued, fever usually subsides within a few days.
