Other examples are ivermectin, hydroxychloroquine or chloroquine.
Claims that ivermectin, hydroxychloroquine or chloroquine can treat COVID-19 are false. These medicines are still useful for treating other illness. But only medicines approved or authorized by the FDA to treat COVID-19 are useful for that illness.
Ivermectin treats or prevents parasites in animals and in humans, not viruses. Taking large doses of this drug can cause serious harm.
