Background: Valproate is widely prescribed medication for the control of seizures in pediatric population. It has been reported to be an important implication for drug induced pancreatitis. A case of valproate induced acute pancreatitis operated as surgical abdomen has been reported here. Case Report: A 13-year-old child presented to the emergency department with severe pain and abdominal distension associated with vomiting and constipation for four days. The patient’s care givers did not disclose any medication history. Based on clinical examination and ultrasonography that revealed mild free fluid, provisional diagnosis of pyoperitoneum with peritonitis was made. An emergency exploratory laparotomy was undertaken during which acute pancreatitis was diagnosed intra-operatively. On further enquiry the caregiver revealed the history of valproate intake for last six months for generalized tonic‑clonic seizures. Valproate was discontinued and there was complete resolution of symptoms. Conclusion: Both clinicians as well as care givers of paediatric patients receiving valproate should be watchful regarding this possible life-threatening complication to avoid delay in diagnosis and appropriate management
