Sri Lanka, Dec. 17 -- The investigations are underway into a batch of the anaesthesia-related drug Ondansetron, following reports of two deaths that raised concerns over its safety, Deputy Minister of Health Hansaka Wijemuni said.

He told media that Ondansetron is commonly administered to prevent side effects during anaesthesia.

He noted that millions of doses of the drug have been imported and used since April, with no adverse reactions reported until November.

According to Wijemuni, five patients at the Jayewardenepura Hospital reported minor side effects last month. These cases were reviewed by the National Medicines Regulatory Authority (NMRA), which allowed continued use of the drug while advising vigilance and further testing.
