Taiwan Centres for Disease Control Deputy Director-General Chuang Jen-hsiang told reporters on Tuesday that medical experts had decided to provisionally allow dexamethasone to be listed as a Covid-19 treatment but that procedures still needed to be completed before it could be given to any patients.

Taiwan has reported 476 cases of the new coronavirus, including seven deaths.

Most of the cases are imported and almost all have recovered. It has kept numbers low thanks to early and effective prevention work.

Taiwan’s official Central News Agency said this week that stocks on the island of US drugmaker Gilead’s Covid-19 medicine remdesivir were low.

Taiwan had originally ordered 2,000 doses to arrive by the end of July, but had only 78 in stock, enough to treat 54 seriously-ill patients, the report said.

Remdesivir is the only drug so far authorised in the European Union to treat patients with severe symptoms of Covid-19.

Remdesivir is in high demand after the intravenously-administered medicine helped to shorten hospital recovery times in a clinical trial.

But in results announced in June, a trial by researchers in the UK showed dexamethasone as the first drug to save lives of Covid-19 patients in what scientists said was a major breakthrough in the coronavirus pandemic.

Japan last month also approved the use of dexamethasone to treat Covid-19.
