Ivermectin Treats Many Infections in Humans – Just Not COVID-19

3 minutes, 9 seconds Read

While the recent focus on Ivermectin 3mg tablets has primarily been in the context of COVID-19, with largely inconclusive and unsupportive results, it’s crucial to remember its established and significant role in treating a wide range of parasitic infections in humans. Here’s a deeper look at its proven applications:

A Spectrum of Parasitic Foes:

Ivermectin acts as a broad-spectrum antiparasitic agent, effectively targeting various internal and external parasites that plague human health. Its primary areas of effectiveness include:

  • Filarial Diseases: These infections, caused by threadworm parasites, encompass:
    • Onchocerciasis (River Blindness): Ivermectin significantly reduces the transmission of the parasite and prevents blindness caused by this debilitating disease. you can also try

    • Lymphatic Filariasis (Elephantiasis): It plays a crucial role in mass drug administration programs aimed at controlling this chronic condition characterized by swelling of limbs and other body parts.
  • Other Worm Infections: Ivermectin effectively treats:
    • Strongyloidiasis: An intestinal infection caused by a specific type of roundworm.
    • Cutaneous Larva Migrans: This condition results from the migration of parasite larvae under the skin, causing intense itching and inflammation. Ivermectin effectively eliminates these larvae.
    • Scabies and Head Lice: Topical application of ivermectin cream or lotion eradicates these highly contagious skin parasites.

Beyond Worms:

While primarily known for its antiparasitic properties, ivermectin demonstrates potential in other areas:

  • Dengue Fever and Other Viral Infections: Research suggests ivermectin possesses antiviral activity against various viruses like dengue, Zika, and yellow fever, although further investigation is needed to determine its clinical efficacy.
  • Certain Skin Conditions: Topical ivermectin has shown promising results in treating rosacea, a chronic inflammatory skin disorder.

Safety and Efficacy:

Ivermectin boasts a well-established safety profile when used as prescribed. Its effectiveness against targeted parasitic infections is well documented, with the World Health Organization (WHO) recognizing its critical role in mass drug administration programs for lymphatic filariasis and onchocerciasis.

Important Caveats:

It’s crucial to emphasize that:

  • COVID-19 Ineffectiveness: Despite initial hype and some early studies suggesting potential, large-scale clinical trials and meta-analyses have not shown consistent evidence of ivermectin’s effectiveness against COVID-19.


  • Dosage and Misuse: Ivermectin dosages for human parasitic infections are significantly lower than those used in veterinary applications. Taking excessive amounts or using animal formulations can lead to serious adverse effects.


  • Off-Label Use: While ivermectin has shown promise in some areas beyond its approved indications, further research and clinical trials are necessary before widespread adoption for such uses.


  • Mechanism of Action: Ivermectin disrupts the nervous system of parasites by binding to specific glutamate-gated chloride channels. This binding leads to an influx of chloride ions, causing hyperpolarization and ultimately paralysis of the parasite.


  • Cost-Effectiveness: Ivermectin is a relatively inexpensive drug, making it a valuable tool for mass drug administration programs in developing countries where parasitic infections are widespread.


  • Drug Interactions: It’s crucial to be aware of potential interactions between ivermectin and other medications, particularly those affecting the liver or the P-glycoprotein pump, which helps limit ivermectin’s penetration into the central nervous system.


  • Emerging Research: While not yet conclusive, ongoing research explores the potential of ivermectin in other areas, such as:
    • Malaria: Some studies suggest possible activity against certain malaria parasites, but further investigation is needed.
    • Autoimmune Diseases: Preliminary research explores the immunomodulatory properties of ivermectin, potentially offering benefits in conditions like rheumatoid arthritis.


  • Responsible Use: It’s vital to emphasize the importance of using ivermectin only under medical guidance and adhering to prescribed dosages. Self-medication or using veterinary formulations can lead to serious adverse effects.



Ivermectin remains a vital tool in the fight against various parasitic infections in humans. Its established safety profile and proven efficacy against these conditions make it a cornerstone of public health initiatives in many regions. However, it’s essential to remember that its effectiveness against COVID-19 has not been substantiated by robust scientific evidence, and its use for this purpose is not recommended.
