Abstract

Importance: It is unknown whether ivermectin, with a maximum targeted dose of 600 μg/kg, shortens symptom duration or prevents hospitalization among outpatients with mild to moderate COVID-19. Objective: To evaluate the effectiveness of ivermectin at a maximum targeted dose of 600 μg/kg daily for 6 days, compared with placebo, for the treatment of early mild to moderate COVID-19. Design, Setting, and Participants: The ongoing Accelerating COVID-19 Therapeutic Interventions and Vaccines 6 (ACTIV-6) platform randomized clinical trial was designed to evaluate repurposed therapies among outpatients with mild to moderate COVID-19. A total of 1432 participants older than 30 years with confirmed COVID-19 experiencing at least 2 symptoms of acute infection for less than or equal to 7 days were enrolled at 93 sites in the US from February 16, 2022, through July 22, 2022, with follow-up data through November 10, 2022. Interventions: Participants were randomly assigned to receive ivermectin, with a maximum targeted dose of 600 μg/kg (n = 708) daily, or placebo (n = 724) for 6 days. Main Outcomes and Measures: The primary outcome was time to sustained recovery, defined as at least 3 consecutive days without symptoms. The 7 secondary outcomes included a composite of hospitalization, death, or urgent/emergent care utilization by day 28. Results: Among 1432 randomized participants who received study medication or placebo, the median (IQR) age was 48 (38-58) years, 854 (59.6%) were women, and 1188 (83.1%) reported receiving at least 2 SARS-CoV-2 vaccine doses. The median (IQR) time to sustained recovery was 11 (11-12) days in the ivermectin group and 12 (11-12) days in the placebo group. The hazard ratio for improvement in time to recovery was 1.02 (95% credible interval, 0.92-1.12; P value for efficacy = .65). Among those receiving ivermectin, 39 (5.5%) were hospitalized, died, or had urgent or emergency care visits compared with 42 (5.8%) receiving placebo (hazard ratio, 0.97 [95% credible interval, 0.60-1.45]; P = .55). In the ivermectin group, 1 participant died and 6 were hospitalized (1.0%); 2 participants (0.3%) were hospitalized in the placebo group and there were no deaths. Adverse events were uncommon in both groups. Conclusions and Relevance: Among outpatients with mild to moderate COVID-19, treatment with ivermectin, with a maximum targeted dose of 600 μg/kg daily for 6 days, compared with placebo did not improve time to sustained recovery. These findings do not support the use of ivermectin in patients with mild to moderate COVID-19. Trial Registration: ClinicalTrials.gov Identifier: NCT04885530

    Achieving drug levels sufficient for in vitro antiviral activity against SARS-CoV-2 will translate into clinical benefit in patients with COVID-19.

    Time to sustained recovery is a clinically meaningful end point for outpatients with mild or moderate COVID-19.

    “Among outpatients with mild or moderate COVID-19, treatment with ivermectin, with a targeted maximum dose of 600 μg/kg daily for 6 days, was not shown to improve time to sustained recovery compared with placebo.”
  • The paper relies on this without support.

    The earlier null results for ivermectin at 400 μg/kg for 3 days were due to insufficient dose or duration rather than lack of efficacy.

    “This large clinical trial addresses a potential gap in knowledge by testing (1) a higher daily dose (targeted maximum dose of 600 μg/kg) and ( 2) a longer (6-day) duration of ivermectin.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-05.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-05.

Statistics and arithmetic are recomputed, not judged.
