WHO temporarily suspended research on antimalarial drugs hydroxychloroquine and chloroquine to treat coronavirus infection. This was announced by Director General of the organization Tedros Adan Ghebrejesus. Pause had to be taken to study new data on the side effects of the drug and to make sure its safety.
Hydroxychloroquine is used by doctors in different countries to treat COVID-19, but its effectiveness has not yet been clinically proven. Physicians have reported side effects of the drug. According to one report, it may affect the heart rate and lead to arrhythmia. Severe psychoneurological disorders, such as psychosis and suicidal thoughts, have been reported in Spanish patients.
At the same time, hydroxychloroquine is actively used for COVID-19 treatment in many countries. For example, the UK ordered a drug worth 35 million pounds sterling; the Minister of Health of Brazil recommended hydroxychloroquine and chloroquine to treat even mild cases. And President Trump has admitted that hydroxychloroquine is also used to prevent COVID19. The Russian Ministry of Health also recommended the drug.
