HCQ prophylaxis RCT with 201 weekly HCQ patients, 197 daily HCQ patients, and 200 control patients, concluding the prophylaxis is safe. There were no grade 3 or 4 AEs, SAEs, ER visits, or hospitalizations. There was only 4 confirmed cases, 2 in the placebo arm and one in each HCQ arm. 60% of patients had exposure at baseline.
HCQ 400mg weekly or HCQ 200mg daily after a loading dose of 400mg on day 1.
