Omeprazole, a common medication for acid reflux, may cause severe exfoliative dermatitis, a widespread skin reaction. This case highlights a rare but persistent adverse drug reaction, emphasizing the need for vigilance in dermatological diagnosis.

Area of Science:

  • Dermatology
  • Pharmacology
  • Internal Medicine

Background:

  • Proton pump inhibitors (PPIs) like omeprazole are widely used for gastroesophageal reflux disease (GERD).
  • Drug-induced exfoliative dermatitis is a serious adverse reaction with various potential triggers.
  • Previous literature has rarely implicated omeprazole in exfoliative dermatitis.

Observation:

  • A 41-year-old male patient developed severe, widespread exfoliative scaling on his back, trunk, and legs.
  • Skin manifestations included redness and extreme sloughing, particularly on the hands.
  • Symptoms persisted for 18 months despite omeprazole discontinuation and treatment with steroids.

Findings:

  • Omeprazole use (20 mg twice daily for 3 months) preceded the onset of exfoliative dermatitis.

  • The patient's persistent symptoms suggest a prolonged or severe reaction to omeprazole.
  • This case adds to the limited evidence linking omeprazole to exfoliative dermatitis.

    • Implications:

    • Clinicians should consider omeprazole as a potential cause of exfoliative dermatitis, even if rare.
    • Persistent skin reactions warrant thorough investigation into medication side effects.
    • Further pharmacovigilance is needed to fully understand omeprazole's dermatological adverse event profile.
