I believe that the daily dose for lupus and rheumatoid arthritis is more than the covid daily dose.

Here are the recommendations for HCQ dosing by that fly-by-night medical operation, The Mayo Clinic (https://www.mayoclinic.org/drugs-supplements/hydroxychloroquine-oral-route/proper-use/drg-20064216):

Dosing

The dose of this medicine [hydroxychloroquine] will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of this medicine. If your dose is different, do not change it unless your doctor tells you to do so.

The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.

For oral dosage form (tablets):

At first, 6.5 mg per kilogram (kg) of body weight, not to exceed 400 mg, once weekly on the same day of the week starting 2 weeks before traveling to an area where malaria occurs, and continued for 4 weeks after leaving the area.
