The debate surrounding ivermectin's potential as a COVID-19 treatment has captivated both scientific circles and the general public. However, the latest evidence from the UK PRINCIPLE trial ivermectin results—one of the largest community-based COVID-19 clinical trials in the world—has provided a conclusive stance: ivermectin is unlikely to improve outcomes for COVID-19 patients. This finding is crucial for shaping public health responses, treatment guidelines, and public opinion.
In this blog, we analyze the final findings of the UK PRINCIPLE trial, evaluate their clinical relevance, and compare ivermectin’s efficacy to other available COVID-19 treatments in the UK. We'll also review peer responses, address trial limitations, and explore the implications for UK healthcare policy.
? Summary of PRINCIPLE Trial Final Results
The UK PRINCIPLE trial (Platform Randomised trial of INterventions against COVID-19 In older peoPLE) was a multi-arm, adaptive platform trial led by the University of Oxford. The study aimed to identify effective treatments for COVID-19 in community settings, particularly among those at higher risk of complications.
? Key Details:
- Trial Name: PRINCIPLE
- Drug Studied: Ivermectin
- Dose: 300–400 μg/kg daily for 3 days
- Participants: 1,206 COVID-positive patients
- Control Group: 774 patients
- Study Period: June 2021 – March 2022
- Setting: Community-based, UK-wide
? Findings:
- No meaningful reduction in time to recovery
- No statistically significant impact on hospitalizations or deaths
- Conclusion: Ivermectin did not significantly improve ivermectin COVID patient outcomes UK compared to usual care
? “Our findings do not support the use of ivermectin for treating COVID-19 in the community setting,” – PRINCIPLE Trial Research Team.
For those considering treatment options, Ivermectin 6mg and Ivermectin 12mg are still available at Medicoease, but not for COVID-19 use unless otherwise prescribed.
? Statistical Significance and Clinical Relevance
? Primary Endpoint:
Time to recovery based on self-reported data
- Ivermectin group: 12.9 days (mean)
- Control group: 12.7 days (mean)
- Difference: Statistically insignificant
? Secondary Endpoints:
Hospitalizations and deaths due to COVID-19
- Ivermectin: 3.4%
- Control: 3.2%
- Conclusion: No clinical advantage
? Clinical Relevance:
While some early global studies reported promising results, the clinical trial ivermectin efficacy COVID-19 data from this UK-based trial provides a high level of evidence against its use for COVID treatment.
?♂️ Patient Outcomes Studied (Recovery, Hospitalization)
The trial carefully tracked multiple patient-centered outcomes, with the following highlights:
? Time to Recovery:
Measured through patient self-reporting from symptom onset
- No improvement in average time to resolution of symptoms
- Slight variation within margin of error
? Hospitalization Rates:
- Minor numerical difference, but no statistical evidence to link ivermectin to fewer hospital admissions
⚰️ Mortality:
- No significant difference between groups
- Aligns with other PRINCIPLE trial conclusion ivermectin findings
? “This further reinforces that ivermectin is unlikely to help COVID-19 patients recover faster or avoid hospitalization,” – NHS spokesperson.
? Trial Limitations and Peer Review Comments
? Limitations:
- Open-label design (no placebo), raising concerns of bias
- Self-reported recovery is inherently subjective
- Participants largely vaccinated, potentially limiting observable benefits
- Focused on mild-to-moderate cases, not severe COVID-19
? Peer Review Insights:
- Published in The Lancet Respiratory Medicine (2023)
- Praised for large-scale, community-centered methodology
- Criticized for lack of placebo control
- Supported by Oxford and the UK government for methodological transparency
Despite criticisms, the ivermectin treatment COVID UK study remains one of the strongest real-world assessments of the drug's lack of effectiveness in COVID-19.
? Comparison to Other COVID-19 Treatments
With ivermectin UK findings now considered conclusive, what treatment options remain viable?
✅ Approved and Recommended:
- Paxlovid (nirmatrelvir + ritonavir) – proven to reduce hospitalization
- Molnupiravir – used for high-risk non-hospitalized patients
- Remdesivir – for hospitalized patients with confirmed lower respiratory tract involvement
? Comparison Chart:
Treatment | Outcome Improvement | Evidence Strength |
Ivermectin | ❌ No improvement | Weak |
Paxlovid | ✅ Strong effect | Strong |
Molnupiravir | ✅ Mild effect | Moderate |
Remdesivir | ✅ Hospital setting | Strong |
This chart echoes the broader COVID trial results, supporting a shift away from ivermectin.
?? Healthcare Implications in the UK
The findings have already impacted clinical guidance and policy.
?️ NICE and NHS Guidance:
- No recommendation for ivermectin in COVID-19 treatment
- Emphasis on evidence-based therapeutics
- Ivermectin removed from consideration in active treatment protocols
? For Clinicians:
Doctors are discouraged from prescribing ivermectin for COVID-19 unless under controlled trials.
? For Patients:
Self-medicating with ivermectin is discouraged. Based on the ivermectin outcomes, there is no benefit for COVID-19 treatment.
? Media and Public Response
?️ UK Headlines:
- “Oxford PRINCIPLE trial rules out ivermectin for COVID” – The Guardian
- “Another COVID cure myth debunked” – BBC
- “Time to move on from ivermectin?” – Sky News
? Public Reactions:
- Mixed responses on social media
- Anti-vaccine groups claim bias, despite transparent peer-reviewed process
- Medical professionals cite the study to combat misinformation
? Viral Narratives:
Despite a vocal minority pushing ivermectin as a cure, the UK COVID treatment strategy remains grounded in science and focused on antivirals with proven efficacy.
? Future Outlook: What's Next?
? Research Directions:
- Continued focus on antivirals like Paxlovid
- Investigating long COVID treatments
- No further ivermectin trials planned in the UK
? Public Education:
- Combating misinformation remains key
- Promoting trust in data-driven trials
- Supporting community health literacy

1. ? What is the UK PRINCIPLE trial?
A government-funded, Oxford-led study testing treatments for COVID-19 in high-risk individuals in community settings.

Only from trusted platforms like Medicoease, which offers Ivermectin 6mg and Ivermectin 12mg.
6. ? Why do some people still believe in ivermectin for COVID?
Largely due to early misinformation, social media narratives, and anecdotal reports.
