Bellastesin-Associated Methemoglobinemia in a Patient with Liver Alveococcosis

Abstract

The presented clinical observation and analysis of the literature data draws an attention on the possibility of developing a life-threatening condition such as methemoglobinemia due to the use of the benzocaine preparation. The latter is part of the preparation bellastesin for the treatment of gastroenterological diseases. This drug is often taken by patients at their own at discretion and with no proper control and consideration of existing co-morbidities. In addition, one needs to pay attention on the indicators of oximetry, including the level of methemoglobin, when diagnosing diseases accompanied by cyanosis and respiratory insufficiency.
