Case report: ofloxacin-induced hypersensitivity vasculitis

Area of Science:

• Pharmacology and Toxicology
• Dermatology
• Rheumatology

Background:

• Ofloxacin, a widely used fluoroquinolone antibiotic since 1985, has a known profile of potential adverse effects.
• While uncommon, skin reactions have been documented with ofloxacin use.
• Hypersensitivity vasculitis is a rare but serious adverse drug reaction.

Observation:

• This report details a specific case of a patient experiencing severe vasculitis.
• The vasculitis affected both legs, necessitating significant medical intervention.
• The condition was directly attributed to the use of ofloxacin.

Findings:

• A direct causal link between ofloxacin and hypersensitivity vasculitis was established in this patient.
• The severity of the vasculitis required advanced treatment, including plastic surgery.
• This case highlights a rare but critical adverse effect of ofloxacin.

Implications:

• Clinicians should be aware of the potential for ofloxacin-induced hypersensitivity vasculitis, even if rare.
• Early recognition and diagnosis are crucial for managing severe cutaneous drug reactions.
• This case underscores the importance of monitoring patients for unusual adverse events associated with common antibiotics.
