Treatment for severe COVID patients seeing global shortages
Less than two months after the Food and Drug Administration granted emergency authorization for the treatment Actemra for severely sick COVID-19 patients, there are already global shortages due to an "unprecedented surge in worldwide demand," the manufacturer, Roche, said.
Actemra helps fight the inflammatory immune reaction some COVID-19 patients have with severe infection.
Roche said employees have been "working around the clock" to boost production and distribution.
"Despite all these efforts, the unfortunate reality is that due to the unprecedented surge in worldwide demand -- with US demand spiking to well-beyond 400% of pre-COVID levels over the last two weeks alone -- we will experience shortages of Actemra/RoActemra globally over the weeks and months ahead," Roche said. "This is due to global manufacturing capacity limits, raw material supply constraints, the complex, labour-intensive process of manufacturing biologics and the dynamically evolving nature of the pandemic."
The World Health Organization added Actemra to its list of COVID-19 treatments in July following FDA authorization.

Orlando residents asked to limit water usage with liquid oxygen in short supply
A Florida utility company asked Orlando residents to limit their water usage as liquid oxygen, which is used to treat COVID patients as well as help purify and clean water, is in short supply amid record COVID-19 hospitalizations.
Orlando Utilities Commission asked residents to limit watering their lawns "immediately" in a statement posted to Twitter Friday afternoon.
"A regional shortage of liquid oxygen linked to the surge of COVID-19 hospitalizations is impacting OUC's ability to treat drinking water," the company said.
The company said it needs to conserve up to half the water used daily until supplies return to normal while asking people to limit their non-critical water usage for at least two weeks.
"If OUC's liquid oxygen supplies continue to be depleted and water usage isn't reduced, water quality may be impacted," the company said in an update on its website.
OUC provides water service to about 140,000 customers, according to Orlando ABC affiliate WFTV.
The Florida Hospital Association reported a record 16,973 COVID-19 hospitalizations on Thursday. More than half of adults in intensive care units have COVID-19, it said.
