The results presently available from randomised clinical trials and their meta-analysis indicate that Hydroxychloroquine is not associated in COVID-19 patients with either decreased mortality or clinical worsening. Thus, the use of Hydroxychloroquine in COVID-19 patients cannot at present be encouraged. However, the hypothesis that Hydroxychloroquine might have a beneficial role in subgroups of patients at low risk and/or when used at low dosage (≤ 400 mg/day) deserves to be tested in large, well designed randomised clinical trials.
