Ivermectin and Cancer: Unraveling the Potential Link and Emerging Therapeutic Prospects

Ivermectin, a well-known antiparasitic drug, has garnered significant attention in recent years for its potential role in cancer treatment and prevention. Originally developed to combat parasitic infections, this drug has demonstrated promising anti-cancer effects in numerous preclinical studies and some early-stage clinical trials. While the mechanisms underlying its anti-cancer properties are still being elucidated, the available evidence suggests that ivermectin could be a valuable addition to the oncology arsenal. In this article, we will explore the current state of research on ivermectin and its implications for cancer treatment and prevention.

Ivermectin's Mechanisms of Action

Ivermectin exerts its primary anti-parasitic effects by targeting and binding to glutamate-gated chloride channels in invertebrate neurons, leading to paralysis and death of parasites. However, it has been discovered that ivermectin also influences various cellular processes in mammalian cells, which might be relevant to its anti-cancer potential. Some of the proposed mechanisms include:

  1. Autophagy modulation: Ivermectin has been found to modulate autophagy, a cellular process responsible for removing damaged organelles and proteins, which can be dysregulated in cancer cells. By promoting or inhibiting autophagy, ivermectin could influence cancer cell survival and proliferation.

  2. Inhibition of DNA repair: Preclinical studies have suggested that ivermectin may interfere with the repair of DNA damage in cancer cells, thereby promoting their vulnerability to other anti-cancer treatments like chemotherapy and radiation.

  3. Immunomodulation: Ivermectin has been shown to have immunomodulatory effects, potentially enhancing the body's immune response against cancer cells.

Preclinical Evidence

Numerous in vitro and in vivo studies have explored ivermectin's anti-cancer effects across various cancer types. For instance, research has shown that ivermectin inhibited the growth of breast cancer cells, lung cancer cells, colon cancer cells, and even glioblastoma cells. Moreover, combination therapies involving ivermectin and conventional anti-cancer drugs have demonstrated synergistic effects, enhancing treatment efficacy.

Clinical Trials and Observational Studies

While preclinical evidence is encouraging, the translation of ivermectin's anti-cancer properties into clinical settings requires rigorous evaluation through well-designed clinical trials. As of my last knowledge update in September 2021, there were some early-stage clinical trials exploring ivermectin's use in cancer treatment. However, it is crucial to interpret these findings with caution, as larger, randomized, and controlled trials are necessary to establish its true potential.

Potential Challenges and Safety Concerns

Despite the promising data, several challenges need to be addressed. Firstly, the optimal dosage and treatment regimen for cancer patients must be determined. Secondly, potential side effects and interactions with other cancer treatments need thorough evaluation to ensure patient safety.

It is essential to acknowledge that ivermectin's primary use remains in combating parasitic infections, and its off-label use for cancer treatment is still an area of active investigation. Physicians must weigh the risks and benefits carefully when considering ivermectin as an adjunct to standard cancer therapies.


While the evidence for ivermectin's anti-cancer properties is growing, it is crucial to approach this topic with scientific skepticism and continue supporting rigorous research in clinical settings. Ivermectin holds immense potential as a supplementary cancer therapy, and future investigations may unveil its full therapeutic capabilities.

As a consumer, this is very new concepts and is NOT A CURE FOR CANCER.

As a physician, I will stay updated with the latest research and evidence on ivermectin and cancer will allow for informed decision-making and optimal patient care.
