I have read that Chloroquine has a cumulative effect. In other words, long term usage is the real problem. The upper limit is cumulative dosages amounting to 1000 grams. As I understand the regimen for Covid 19, it involves a dosage of 500 mg. for 10 days, or a cumulative total of 5 grams. I don’t think that would cause anyone a problem.
