Good Morning Britain's Dr Sarah Jarvis has responded to a coronavirus treatment and 'cure' publicised by President Donald Trump.
In an urgent warning to GMB viewers, ITV's health expert expressed the dangers of taking this drug and stressed we must "look at the evidence."
A video - which has since been taken down - was shared by Donald Trump on social media promoting the anti-malaria drug, hydroxychloroquine, as an effective treatment and preventative measure for Covid-19, Birmingham Live reports.
Dr Sarah Jarvis debunked reports hydroxychloroquine was effective in treating the virus by highlighting one of its dangerous side effects - which you can watch in the video above.
She warned: "It is absolutely not a viable prospect. There were some controversial trials using hydroxychloroquine with another drug and antibiotic.
"We already use hydroxychloroquine for the treatment of a condition called lupus and it can be very effective – but we know that all drugs have side effects."
Dr Sarah continued: "In COVID, there is a real risk to your heart and one of the issues with hydroxychloroquine is a risk to your heart.
"And there have been some very controversial results from different studies.
"There is no conclusive evidence that it reduces risk and some conclusive studies have shown that it increases risk to your heart"
The President told a press conference: "I think [hydroxychloroquine] could have a very positive impact in the early stages [of COVID].
"And I don't think you lose anything by doing it other than politically it doesn't seem to be too popular when I recommend it.
"Do you know why? Because when I recommend something they like to say don't use it."
But Sarah hit back: "When the body is attacking itself and you have an overreaction of the immune system, at that stage, a drug like dexamethasone can reduce the risk of dying of someone that's been ventilated by about 30 per cent.
"But it probably won't work at other stages.
"We have to look at the evidence."
Good Morning Britain airs weekdays from 6am on ITV
