RT Journal Article SR Electronic T1 Cotton Fever: A Condition Self-Diagnosed by IV Drug Users JF The Journal of the American Board of Family Medicine JO J Am Board Fam Med FD American Board of Family Medicine SP 276 OP 279 DO 10.3122/jabfm.2016.02.150267 VO 29 IS 2 A1 Ashley Michelle Zerr A1 Kimberly Ku A1 Areeba Kara YR 2016 UL http://www.jabfm.org/content/29/2/276.abstract AB The presentation of fever in an intravenous drug user prompts diagnostic testing targeted at identifying infectious etiologies. However, an alternate diagnosis exists in “cotton fever.” While few reports describe this phenomenon in the peer-reviewed literature, the diagnosis is well recognized among the intravenous drug user community. Although its etiology is not well understood, cotton fever seems to be a self-limited, febrile response to the intravenous administration of a drug filtered through cotton. Educating clinicians regarding cotton fever may limit unnecessary hospital admissions and improve our ability to care for this population.
