The manufacturing licence of Noida-based pharmaceutical firm Marion Biotech has been cancelled by the Uttar Pradesh authorities, according to officials. Marion Biotech's cough syrup Dok-1 was linked with the death of 18 children in Uzbekistan. 

According to a government official, the firm's licence was under suspension since January, after which a detailed inquiry was initiated. Now the licence of the firm has been cancelled by the Uttar Pradesh Drugs Controlling and Licensing Authority. The firm can no longer manufacture the syrup.

The production licence of the firm was suspended in January after inspections at its site by the central and state drug authorities in the wake of the controversy. On January 12, the World Health Organization (WHO) also issued a 'medical product alert', referring to two substandard (contaminated) products identified in Uzbekistan and reported to it on December 22, 2022.
