New Delhi, Oct. 8 -- The Delhi Drugs Control Department has directed all cough syrup manufacturers in the Capital to suspend sales until their raw materials and finished products are tested for diethylene glycol (DEG), a toxic industrial solvent, following the deaths of 17 children in Madhya Pradesh and Rajasthan allegedly linked to a contaminated cough syrup. "Following the death of children due to adulterated cough syrup, namely Coldrif Syrup, which was found to have DEG, we have decided to take measures," said a health official, requesting anonymity. Officials said seven pharmaceutical manufacturers in Delhi produce cough syrups under various brand names. The notice to these firms, seen by HT, directs that "all the solvent(s), raw material and finished preparation of cough syrups may compulsorily be tested for presence of Diethylene Glycol (DEG)." Manufacturers have been warned not to release products "without testing for DEG" and to maintain stock records. Chemist associations have been told to stop selling Coldrif, Respifresh and Relife. "We have collected samples from supply points. Reports are expected within 15 days," the official said....
