On March 28, the FDA signed an emergency authorization for the use of chloroquine to treat patients hospitalized with COVID-19.

The day before that action, Cuomo amended his previous restrictions on the drug.

The new rules allow health care providers to prescribe the drug for “patients in inpatient settings and acute settings; for residents in a subacute part of a skilled nursing facility; or as part of an study approved by an Institutional Review Board.” The change means that doctors in New York can now prescribe chloroquine to COVID-19 patients in hospitals and emergency rooms, but not in outpatient settings.

It’s use for treatment of malaria, lupus, erythematosus and rheumatoid arthritis previously approved by the FDA remains unchanged.
