This is a common reported exclusion, due to the potential toxicity of the excipient.
Dose in gout is usually 0.6 mg, this dose is reported for the COLCORONA trial.
These drugs do have some clearance by kidneys, so accumulation with occur with chronic dosing, not relevant in the COVID-19 setting.
CrCl < 30 an exclusion in the COLCORONA trial
CQ: chloroquine; HCQ: hydroxychloroquine; CrCl: creatinine clearance.
