The controversial animal parasite treatment Ivermectin will be allowed for what is called controlled compassionate use in the treatment of Covid-19 in South Africa after The South African Health Products Regulatory Authority’s chief executive said they remain concerned about the lack of scientific data for human use, but find themselves in a pandemic with limited options. Under compassionate-use rules, medical practitioners will have to apply on a case-by-case basis to give ivermectin to patients under their care, in what is expected to be for the symptomatic treatment of Covid-19, rather than as a prophylaxis against the disease, which is reportedly how some South Africans are using it – against medical advice.
