At least 17 people were died after drinking cough syrup suspected of being toxic.
A police officer said the dead were all drug addicts who apparently drank the cough syrup in an attempt to get high. They died at various hospitals in the eastern city of Lahore over the past three days.
He said five other addicts who drank the cough syrup were also being treated.
While taking action, Punjab Health Department immediately banned sale of the syrup and directed drug inspectors to raid medical stores to confiscate the remaining stock.
