NHS Direct has now closed, according to nhsdirect.nhs.uk, despite the help service being scheduled to cease operation on March 31st.
A message on the NHS Direct website said users could still check symptoms on the NHS choices page.
The closure of the telephone and online health advice provider follows the NHS trust’s announcement it was pulling out of all 11 of its NHS 111 contracts because they were "financially unsustainable."
Dance teacher Thema Davis called 111 in April when she suffered an attack of Gastroparesis, a stomach condition.
But the people she spoke to told her she would have to answer 50 questions before she could see a doctor.
"I was left for so long that I got so dehydrated that my kidneys almost failed," she said.
ITV News science and medical editor Lawrency McGinty has this report:
Shadow health secretary Andy Burnham said: "This is a mess of ministers' own making. Jeremy Hunt was warned that this would happen but he chose to plough on regardless.
"It's not good enough Jeremy Hunt hiding behind his officials. He must take responsibility and put a plan in place to ensure a safe and sustainable service in all parts of England.
"The destruction of NHS Direct, a trusted, national service, is one of the worst acts of vandalism by this Government. It has been broken up into 46 cut-price contracts. Computers have replaced nurses and too often the computer says 'go to A&E'."
"The vast majority of the country are getting an excellent service," Lord Howe insisted today.
The Health Minister told ITV News that "the failings [of the service] are isolated and very few."
A prominent Liberal Democrat peer has praised the troubled NHS non-emergency telephone service 111 for providing him with "efficient and superb" medical assistance after suffering a heart attack.
Speaking during a private notice question (PNQ) on NHS Direct, Lord Willis of Knaresborough said: "On June 9 I had reason to call 111 because I was having a heart attack.
"The response from 111 was not only excellent in York - not only at the same time did they call the paramedics, but they had me in hospital within 25 minutes to an absolutely superb accident and emergency."
NHS England deputy chief executive Dame Barbara Hakin told ITV News NHS 111 is a "great concept" and blamed providers, including NHS Direct, for failing to deliver a quality service:
Dr Malcolm Kendrick told ITV News the111 service is "ridiculous" and says the NHS was "warned and warned" it wasn't going to work:
NHS Direct originally won 11 of the 46 contracts to provide the 111 service.
Earlier this month the company announced that it would be unable to provide the service in North Essex and Cornwall.
But now it is also planning to stop providing the service in Somerset, Buckinghamshire, east London and the City, south-east London, Sutton and Merton, West Midlands, Lancashire and Cumbria, Greater Manchester, Merseyside and Cheshire.
