Fortunately it’s a drug that’s been around for 50+ years originally for malaria prophylaxis and is easy enough to synthesize.
The downside, is that it is unlikely to be found in the US since we don’t deal with malaria very much.
Note: it had very odd side-affects: sweats, mild fever, nightmares, nausea.

I used to be able to buy it when I lived near Toronto Canada ; but don't know where it is currently available in the USA and Canada.
Also, curious if there is any difference between chloroquine phosphate and sulphate, since I came across both while just reading up on it. Or, either works.
Chinese recommendation is more aggressive and dependent on patient weight: https://www.chinalawtranslate.com/en/coronavirus-treatment-p...
Beware these drugs have side effects and interaction with other drugs. A particular feature is that they stay in the body for a very long time. It goes without saying that they should only used under the direction of a knowledgeable physician.
