Coldrif cough syrup, manufactured by Sresan Pharma in Tamil Nadu, was banned by multiple states after official tests confirmed diethylene glycol (DEG) adulteration in a batch linked to clusters of acute kidney injury and child deaths in Madhya Pradesh. In MP's tribal Chhindwara and Betul districts, 20 children under six died over a month after being prescribed the syrup for fever, cough and cold. DEG poisoning causes progressive renal failure. The Central Drugs Standard Control Organisation (CDSCO) issued a nationwide alert. The incident echoed the 2023 Marion Biotech deaths and renewed calls for mandatory GC-MS testing of excipients and stricter QC enforcement for paediatric formulations.
