Ivermectin for COVID-19

4th treatment shown to reduce risk in August 2020, now with p < 0.00000000001 from 105 studies, recognized in 24 countries.

Lower risk for mortality, ventilation, ICU, hospitalization, recovery, cases, and viral clearance.

No treatment is 100% effective. Protocols combine treatments.

5,700+ studies for 169 treatments. c19ivm.org

Prophylaxis study using ivermectin and carrageenan showing 0 of 131 cases from treated healthcare workers, compared to 11 of 98 control.

The effect is likely to be primarily due to ivermectin - the author has later reported that carrageenan is not necessary1.

See2 for discussion of issues with this trial.

5 studies use direct respiratory tract administration3-7

Targeted administration to the respiratory tract provides treatment directly to the typical source of initial SARS-CoV-2 infection and replication, and allows for rapid onset of action, higher local drug concentration, and reduced systemic side effects.

This is the 13th of 105 COVID-19 controlled studies for ivermectin, which collectively show efficacy with p<0.0000000001 (1 in 774 quintillion).

52 studies are RCTs, which show efficacy with p=0.00000021.

This study is excluded in the after exclusion results of meta analysis: concern about potential data issues.

Study covers iota-carrageenan and ivermectin.

risk of case, 96.3% lower, RR 0.04, p < 0.001, treatment 0 of 131 (0.0%), control 11 of 98 (11.2%), NNT 8.9, relative risk is not 0 because of continuity correction due to zero events (with reciprocal of the contrasting arm).
