Gupta said that only children who had taken the pills empty stomach and didn't consumer much water complained about the side effects, which lasted a few hours. "The United Nations and World
Health Organisation had tested the pills before supplying it to the state of Haryana. The pill is to be swallowed and must not be chewed," he said.
He said that the dose has been halved to 50 mg as a precautionary measure. Gupta said the health department had set up seven warehouses for the supply of medicines to government hospitals. He was accompanied by additional deputy commissioner Ashok Garg and civil surgeon Dr Ashok Chaudhry.
