The Government has been making "misleading" comments about controversial pension reforms, the British Medical Association (BMA) said.
As doctors up and down the country take part in industrial action the union spoke out to dispel "partial representations of the facts".
Andrew Lansley's claims that taxpayers subsidise £4 out of every £5 of doctors' pensions is false, the union said.
The NHS pension scheme does not work by building up a pension pot - staff working now pay for the pensions of NHS staff who are retired.
The scheme currently brings in £2 billion more than it pays out - this money goes back to the Treasury.
Just 8% of doctors working in the NHS in England went on strike, according to the Government. More than 20,000 patients were affected.
Doctors are taking industrial action for the first time in almost 40 years but what are the arguments for and against pension reforms?
More than half of people surveyed in an exclusive ITV News poll oppose the doctors' strike over pensions that will take place on Thursday.
