‘Use malaria drugs only for virus emergencies’

PARIS: Anti-malarial drugs chloroquine and hydroxychloroquine should only be used to treat COVID-19 in clinical trials or in case of "national emergency", the European Medicine Agency warned on Wednesday.

Around the world, countries are expanding access to the two compounds, which are used to treat malaria and are known to have anti-viral properties. The medicines have shown early promise against the COVID-19 illness in early studies in France and China.

"It is very important that patients and healthcare professionals only use chloroquine and hydroxychloroquine for their authorised uses or as part of clinical trials or national emergency-use programmes for the treatment of COVID-19," it said.

Both drugs have a number of potentially serious side effects, especially when taken in high doses or administered in tandem with other medications. "They must not be used without a prescription and without supervision by a doctor; prescriptions should not be given outside their authorised uses except in the setting of a clinical trial or nationally agreed protocols," the EMA said in a statement.
