A case report on probable short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing following vairechanika nasya in Ménière's disease.

A 62 year old woman diagnosed with Ménière's disease, who underwent vairechanika nasya (VN) with shadbindu taila presented with short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) like phenomena immediately after the procedure. Rescue measures of abhyanga (local oil massage) and nadi sweda (local fomentation) were administered. Within half an hour the symptoms considerably declined and after 1 hour got completely relieved. The exact symptom disclosure by the patient who herself was a doctor helped in detecting the classic pattern of 'saw tooth phenomena' giving leads into a rare manifestation of probable SUNCT. Naranjo scale yielded zero score and thus the probable causality of VN with shadbindu taila could not be established so as to cause probable SUNCT as an adverse drug reaction (ADR). This case study is not put up for reporting an ADR of VN with shadbindu taila; rather this illustrates an uncommon, yet imperative adverse event of probable SUNCT while undergoing nasya procedure probably due to judgment error while fixing the VN dose in a patient with Ménière's disease. Transparent reporting of such unusual events during panchakarma procedures is necessary so that clinicians can understand, evaluate and take appropriate initiatives to manage them.
