Medication Summary

The choice of medications administered to patients depends on the etiology of the FUO.

Specific examples of treatment

In patients with hepatic granulomas, approximately 50% of patients recover spontaneously, while the other 50% respond to corticosteroid treatment (duration of therapy ranging from a few weeks to several years).

In giant cell arteritis, treat the patient with high doses of steroids, and use intravenous steroids if the patient is very ill or has significant ocular compromise. Carefully monitor the patient, because inadequate treatment and steroid toxicities (eg, hypertension, diabetes, dyspepsia, bone loss, psychosis, cataracts) can cause significant morbidity.

In polymyalgia rheumatica, the treatment consists of amelioration of symptoms with steroid therapy and close monitoring for possible development of GCA.

When drug fever is suspected, discontinue the implicated drug. Stopping the causative drug generally leads to defervescence within 2 days.
