Exploring the Complexities of Ivermectin and Its Covid-19 Controversy
Written on
Understanding Ivermectin: A Dual Perspective
Ivermectin has gained unexpected popularity in various regions, particularly in Latin America, South Africa, and Indonesia, where it's often hailed as a 'miracle drug' for treating Covid-19. This surge in demand has led to a dramatic increase in its price, especially in black market dealings. However, both the World Health Organization (WHO) and the Food and Drug Administration (FDA) have yet to endorse ivermectin for Covid-19 treatment outside of clinical trials.
This situation has birthed two primary viewpoints:
- Ivermectin is largely ineffective or poses potential risks when used for Covid-19.
- It is effective, yet the lack of endorsement may stem from big pharmaceutical companies seeking profit.
The truth likely resides between these extremes, contributing to the ongoing debate and confusion surrounding ivermectin.
A Brief Overview of Ivermectin
Originally identified from soil bacteria in the 1970s in Japan, ivermectin is an FDA- and WHO-approved oral medication primarily used to combat parasitic infections. It is recognized as one of the most essential drugs in both human and veterinary medicine, worthy of significant accolades.
While mainly an anti-parasitic, research has indicated that ivermectin may also possess antiviral properties against several viruses, including Zika, dengue, West Nile, and HIV, with recent studies suggesting efficacy against SARS-CoV-2. The proposed mechanisms of action include inhibiting viral entry, disrupting essential viral enzymes, and reducing inflammation.
Initial studies suggesting a 5000-fold reduction in SARS-CoV-2 replication have spurred further clinical research, though the validity of the clinical data has been compromised by instances of fraudulent research and potential political bias.
The Fabrication of Clinical Data
Ivermectin's clinical path took a tumultuous turn with an April 2020 observational study that reported improved survival rates in Covid-19 patients treated with ivermectin. However, this study relied on data from Surgisphere, a company later found to have fabricated its data. Consequently, this initial preprint study was retracted, as was another study that claimed a six-fold reduction in mortality.
Despite the retractions, the erroneous data had already influenced health authorities in countries like Peru, Brazil, and Bolivia, who endorsed ivermectin treatments based on this flawed evidence.

The Elgazzar Study: A Major Scandal
Another significant scandal emerged from a November 2020 preprint study by Dr. Ahmed Elgazzar and colleagues, claiming a 90% reduction in Covid-19 mortality with ivermectin. However, scrutiny by researchers revealed data inconsistencies and instances of plagiarism. The study was subsequently withdrawn, but not before it had become a cornerstone of ivermectin advocacy, cited extensively in subsequent research and recommendations.
Dr. Meyerowitz-Katz noted that excluding the Elgazzar study from analyses significantly alters the perceived efficacy of ivermectin, underscoring the impact of this single flawed piece of research on the narrative around ivermectin.
Reliable Data and Pharmaceutical Interests
In contrast to the unreliable preprints, more rigorous randomized controlled trials (RCTs) have emerged, albeit with limitations. Dr. Sebastian Rushworth conducted a meta-analysis of credible studies and found that ivermectin may reduce Covid-19 mortality by 62%. This finding, while promising, raises questions about its practical application in high-income countries, which have shown little interest in studying off-patent drugs like ivermectin.
The Illusion of Evidence-Based Medicine
This video discusses how pharmaceutical interests may distort scientific research and public health recommendations, particularly regarding ivermectin.
Balancing Real-World Applications
In many low- and middle-income nations, the healthcare system is overwhelmed. In these contexts, ivermectin may serve as a last resort for patients who lack access to established treatments. While ongoing studies aim to clarify its efficacy, the urgency of the situation often leads healthcare providers to prescribe ivermectin despite its controversial status.
The NIH has found no evidence of harm associated with ivermectin, and while studies suggest it may be safe at prescribed dosages, the lack of conclusive evidence has kept it from being recommended for widespread use in Covid-19 treatment.
Conclusion: A Need for Balance
Ultimately, the situation surrounding ivermectin reflects the complexities of medicine, where scientific evidence must be weighed against practical realities. While ivermectin is not a miraculous solution, its potential benefits in specific contexts cannot be entirely dismissed.
As we navigate this challenging landscape, a balance between rigorous scientific inquiry and compassionate care is essential.
