Naproxen can cause digital vasculitis, a condition affecting blood vessels in the fingers and toes. Stopping the medication reversed these vascular changes, highlighting the importance of considering drug sensitivity in unexplained vascular lesions.

Area of Science:

  • Vascular Medicine
  • Dermatology
  • Pharmacology

Background:

  • Digital vascular lesions can present with diverse etiologies.
  • Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used for pain and inflammation.
  • Drug-induced vasculitis is a recognized but often overlooked adverse effect.

Observation:

  • Three patients presented with digital vasculitis.
  • Naproxen ingestion was identified as the causative agent in all cases.
  • Clinical manifestations included digital ischemic changes and palpable purpura.

Findings:

  • Withdrawal of naproxen led to the complete resolution of vasculitic changes in all three patients.
  • Histopathological examination confirmed leukocytoclastic vasculitis.

  • Naproxen-induced hypersensitivity was deemed the most probable cause.

    • Implications:

    • These cases underscore the necessity of considering naproxen sensitivity in the differential diagnosis of unexplained digital vascular lesions.
    • Clinicians should inquire about medication history, including over-the-counter NSAIDs, when evaluating patients with vasculitis.
    • Early recognition and drug cessation can prevent disease progression and complications.
