ABSTRACT
Introduction: Bullous erythema multiforme (BEM), an immune-mediated, acute condition, frequently includes erosion affecting the oral, genital, and/or ocular mucosa in addition to discrete target-like lesions on the skin. BEM has been linked to various factors, including infections, medications, malignancy, autoimmune disease, immunization, and radiation. Case presentation: Here, we report a case of a 38-year-old married woman who presented with symptoms of reddish-raised, fluid-filled and painful, nonpruritic lesions along with the swelling of bilateral hand and feet. This patient had a history of taking some unrecorded ayurvedic medication for bloating and abdominal pain in a background of antibiotic use before exhibiting the dermatological symptoms of BEM 2 days later. She was successfully managed with ampicillin and cloxacillin, acyclovir and prednisolone. Clinical discussion: A few incidence of BEM after the administration of amoxicillin has been reported, which precipitated only after consuming ayurvedic medication. BEM has a clinical diagnosis with biopsy rarely required. Here, the hypersensitivity reaction induced by the antibiotic itself or by altering the immune response to the concomitant consumed herbal medicine could explain the BEM. Conclusion: Physicians should note that amoxicillin can trigger BEM, regardless of its use with ayurvedic drugs. Antibiotics should be used with caution, especially in patients with a history of BEM.
