Angioneurotic oedema secondary to oral thiamine

Abstract

Although allergic side effects due to parenteral thiamine are well-documented, they are extremely rare when thiamine is used orally. We report a case of a 47-yearold woman who developed angioneurotic oedema secondary to oral ingestion of thiamine at a therapeutic dose. The incident occurred twice with a clear temporal relationship to the initiation on thiamine. Copyright 2013 BMJ Publishing Group. All rights reserved.
