A novel and fatal method of copper sulphate poisoning

Abstract

Copper sulphate is widely used around the world as a pesticide and seed fungicide. Many cases of accidental intoxication with this substance have been reported among farm workers who have absorbed large amounts of the substance through the skin. It has also been used for self-harm, generally by oral ingestion. Toxic levels of the substance can lead to methaemoglobinaemia and death. Case report: The case of a 29 year old woman who diluted and inserted copper sulphate vaginally in order to terminate an unwanted pregnancy is reported. Conclusion: This article is a review of the presentation, diagnosis and treatment of copper-sulphate-induced methaemoglobinaemia, including the challenges of treating this condition in clinical settings that are unprepared for this complication.
