The tests for hydroxychloroquine and chloroquine in the fight against Covid-19 have been temporarily suspended by the World Health Organization (WHO) to evaluate their effectiveness, said its director general, Tedros Adhanom Ghebreyesus.
This decision follows the publication of a study in the medical journal The Lancet judging ineffective, even harmful, the use of chloroquine or its derivatives like hydroxychloroquine against Covid-19.
He noted that these drugs were still considered to be safe for patients with autoimmune diseases and malaria. WHO announced a global “solidarity trial” to find treatments for Covid-19.
The Solidarity trial compares four treatment options against standard care to assess their relative efficacy against Covid-19. Until sufficient data are available, WHO does not recommend that doctors and medical associations recommend or administer these treatments, which have not been shown to work for patients with Covid-19, and taking these drugs as self-medication.
