Dr Hilary Jones has had to tell fans not to ask him about their medical problems over Twitter in the midst of the coronavirus pandemic.
The GP, who regularly appears on ITV's Lorraine and Good Morning Britain, has put a line in his Twitter bio to urge followers to contact their own doctors with any specific queries about their health.
It now reads: "Dr Hilary unfortunately cannot answer any medical enquiries, please contact your GP.
The doctor has been part of a stable of medical experts appearing frequently on TV to reassure the public during the outbreak of the killer virus, which started spreading in January in the Chinese city of Wuhan.
He was forced to apologise on air yesterday for comments he made on Monday's Good Morning Britain about the Irish Health Service, when he claimed it didn't exist.
Speaking to host Piers Morgan about why the UK wasn't closing down schools as a priority, Dr Hilary said: "I think there are many reasons.
"If you look at different countries, they all have different health systems and different circumstances.
"The Republic of Ireland for example, they don't have a Health Service so they must be very worried with how they'd cope with lots of people getting the virus all at once, in other words a sharp peak."
Presenter Susanna Reid then cut in to challenge him, saying: "Sorry, the Republic of Ireland doesn't have a health service?"
Dr Hilary replied: "No, it's largely private isn't it? They don't have a health service to fall back on as such. People pay their GP every time they see them."
His inaccurate remarks were met with a backlash as furious viewers pointed out public health services in Ireland are run by the Health Service Executive (HSE).
Yesterday, Dr Hilary took to Twitter to make amends.
"This morning I apologised on @GMB for the error I made yesterday regarding @HSELive - thank you for the polite messages after I apologised on Twitter yesterday afternoon. Hopefully we can now move on & concentrate on the situation around COVD-19. #HSElive #COVID19.
"Apologies to anyone who thought I was denigrating the Republic of Ireland's HSE. That was never my intention the point I was making is that different countries have different health systems, different demographics & different current circumstances regarding #coronavirus.
"This is why internationally the approaches of scientific & medical experts differ. I understand the service in Ireland is not totally free at the point of delivery as it is under our NHS & I was under a lot of pressure to answer as many questions on todays programme as possible."
He went on: "The bottom line is we all have to pull together on this terrible infection & its consequences. Anger, bitterness & division will not help. Please accept my sincere apologies for the unintentional inaccuracies.
"I know that all the healthcare professionals across all departments within the NHS throughout the UK & Ireland are doing a fantastic job under extreme pressure & circumtances #NHS #HSE."
