The clinical usefulness of chloroquine, and in some recent cases of quinine as well, has been much reduced by the evolution and spread of chloroquine resistant malaria parasites. The mechanism of resistance involves a reduced accumulation of the drug, although again the mechanism involved is controversial. Chloroquine needs to be taken 1-2 weeks before traveling to an area with malaria, compared to some alternatives that can be taken 1-2 days before. chloroquine is only effective against malaria from certain areas of the world. chloroquine may worsen psoriasis, seizures, hearing problems, and liver conditions.

Chloroquine was an essential element of mass drug administration campaigns to combat malaria throughout the second half of the 20th century, and remains one of the World Health Organization’s essential medicines. However, after the malaria parasites Plasmodium falciparum and Plasmodium vivax began exhibiting resistance to the drug in the 1960s and 1980s, respectively, it was replaced by similar antimalarial compounds and combination therapies. A common treatment with chloroquine, a drug commonly used against malaria, has shown signs of effectiveness against the coronavirus, assured Tuesday Didier Raoult, director of the Institut Méditerranée Infection in Marseille, based on the results of a Chinese clinical study.
