FDA issues warnings on chloroquine and hydroxychloroquine after deaths and poisonings reported
The Food and Drug Administration warned consumers Friday against taking malaria drugs chloroquine and hydroxychloroquine to treat Covid-19 outside a hospital or formal clinical trial setting after deaths and poisonings were reported.
The agency said patients taking the drugs for approved reasons, including malaria or to treat autoimmune conditions like lupus, should continue taking their medicine as prescribed.
“Hydroxychloroquine and chloroquine can cause abnormal heart rhythms such as QT interval prolongation and a dangerously rapid heart rate called ventricular tachycardia,” the agency wrote in the notice. “We will continue to investigate risks associated with the use of hydroxychloroquine and chloroquine for COVID-19 and communicate publicly when we have more information.”
