Donald Trump was given an experimental drug “as a precaution” before being moved to Walter Reed medical centre on Friday afternoon, a day after the president was diagnosed with Covid-19.
The decision to move the president to the military hospital in Bethesda, Maryland, came after the White House physician issued a memorandum saying Mr Trump had been treated with an experimental “antibody cocktail” from biotech company Regeneron Pharmaceuticals. Dr Sean Conley wrote that the president was “fatigued, but in good spirits”.
In early-stage clinical trials, Regeneron’s treatment has been shown to reduce the level of the virus and hospital stays when administered early.
In a memorandum issued on Friday afternoon, Dr Conley said Mr Trump has also been taking zinc, vitamin D, melatonin, famotidine — an antacid — and a daily aspirin.
“As of this afternoon the president remains fatigued, but in good spirits,” Dr Conley wrote.
Earlier on Friday, White House chief of staff Mark Meadows had said the president had exhibited “mild symptoms”, but was “not only in good spirits, but very energetic”.
Mr Trump continues to be evaluated by experts and Dr Conley said the first lady, Melania Trump, “remains well with only a mild cough and headache”.
Regeneron shares were up 3 per cent in after-hours trade.
