Abstract
Hydroxychloroquine (HCQ) has shown efficacy against coronavirus disease 2019 (COVID-19) in some but not all studies. We hypothesized
that a systematic review would show HCQ to be effective against COVID-19, more effective when provided earlier, not associated with
worsening disease and safe. We searched PubMed, Cochrane, Embase, Google Scholar and Google for all reports on HCQ as a
treatment for COVID-19 patients. This included preprints and preliminary reports on larger COVID-19 studies. We examined the
studies for efficacy, time of administration and safety. HCQ was found to be consistently effective against COVID-19 when provided
early in the outpatient setting. It was also found to be overall effective in inpatient studies. No unbiased study found worse outcomes
with HCQ use. No mortality or serious safety adverse events were found. HCQ is consistently effective against COVID-19 when
provided early in the outpatient setting, it is overall effective against COVID-19, it has not produced worsening of disease and it is safe.

COVID-19, and that efficacy would be greater if HCQ was
provided earlier in the disease course. We also hypothesized
that some studies that failed to show efficacy would be biased
against positive efficacy and that no unbiased studies would
show worsening. Finally, we hypothesized that HCQ would be
found to be safe.
