As the strike entered its 12th day, Chief Minister Shahbaz Sharif sought the support of the army medical corps.
The army agreed to depute 150 doctors to serve in public hospitals in the province of 90 million people.
"Though 150 doctors may not be enough for five state-run hospitals in Lahore, this will show that the Punjab government is serious about addressing the issue and will not be blackmailed by the striking doctors, whose number is 24,000," Saeed Elahi, parliamentary secretary for health, told PTI.
The striking doctors are only attending to emergency cases.
They have been demanding higher salaries and an improvement in their service conditions.
They warned that if the government takes adverse action against them instead of accepting their demands, they would shut all hospitals in Punjab.
The Punjab government has threatened to sack the striking doctors, who want more allowances, residences, a telephone connection and soft loans to buy cars.
State-run hospitals have been grappling with a critical shortage of staff since the Young Doctors Association began its strike and hundreds of patients have been left unattended.
People have criticised both the doctors and the government for their failure to resolve their differences.
"The doctors at Jinnah Hospital refused to attend to my ailing mother. She has a throat infection but nobody is willing to see her. Where has the humanity of doctors gone?" said Tanvir Ahmed.
He said he was left with no option but to take his mother to an expensive private clinic.
Sharif said his government would not be blackmailed by the doctors.
"We need Rs 4 billion to meet their demands, which we can't afford," he said.
The government had started hiring new doctors to replace those who are on strike.
"Some 600 new doctors have been recruited so far. Besides the services of the army doctors are now at the disposal of the Punjab government," he said.
