Stevens-Johnson Syndrome Induced by Herbal Kadha.

Stevens-Johnson syndrome (SJS) is a dreaded hypersensitivity reaction and a rare immune disorder. We present a Stevens-Johnson syndrome induced by herbal kadha, which may be the first case. A ten-year-old boy presented with massive sloughing, redness, oedematous skin, an oral ulcer, and an inability to feed or drink for two days. The present symptoms started after 12 hours of consuming herbal Kadha, given by a private practitioner in clinics where he was treated for fever. After not responding to earlier treatment, the patient was referred to the present Institute. The patient had a history of seizure disorder and had been on tablet phenytoin for seven months with no history of adverse reactions to it. He was treated in the intensive care unit. Fortunately, he responded to treatment and recovered fully. He received treatment in the form of immunoglobulin and steroids. Phenytoin and herbal kadha were withdrawn, and Clobazam was continued. Natural herbal medicines can develop severe adverse effects. Physicians should remain aware that drug interactions can likely be seen with drugs with a narrow therapeutic index combined with herbal preparations. Clinicians should do more research on the interaction between herbal and prescription medications.
