Abstract
- Fixed drug eruptions (FDEs) are characterized by the presence of site-specific recurrence of a solitary or multiple, well-circumscribed, erythematous macules or patches that recur with each exposure to a particular medication. Several drugs including non-steroidal anti-inflammatory drugs, non-opioid analgesics, sedatives, anticonvulsants, sulfonamides, and tetracycline have been associated with an increased risk of inducing FDE. A 45-year-old woman with known history of levofloxacin use presented with erythematous patches on her face and left forearm. Although a patch test to levofloxacin showed a negative reaction, intradermal tests to assess hypersensitivity to levofloxacin were positive, and she was diagnosed with levofloxacin-induced FDE. Her antibiotic was switched to moxifloxacin, which she tolerated well. Moxifloxacin did not show cross-reactivity. Because of the widespread use of fluoroquinolones, it is important to consider these as possible etiological agents in cases of FDE. We describe a case of FDE diagnosed using positive intradermal tests to detect sensitivity to levofloxacin.
