Usage and Benefits of Human Ivermectin

Ivermectin, a medication that has been widely used to treat parasitic infections in animals, has recently gained attention for its potential uses in humans. This comprehensive guide explores the various applications of human ivermectin and its effectiveness in treating a range of conditions.

One of the most well-known uses of human ivermectin is in the treatment of scabies, a highly contagious skin condition caused by mites. Ivermectin has been proven to be highly effective in killing the mites and relieving the symptoms of scabies, such as itching and rash.

In addition to its use in scabies, human ivermectin has also shown promise in the treatment of other parasitic infections, such as head lice and river blindness. It works by targeting the nervous system of the parasites, causing paralysis and eventually death. This makes it an effective treatment option for these types of infections.

Furthermore, recent studies have suggested that human ivermectin may have antiviral properties, particularly against certain RNA viruses. It has been found to inhibit the replication of viruses such as Zika, dengue, and yellow fever. This has led to speculation that it could potentially be used in the treatment of viral infections, although further research is needed to confirm its efficacy.

Overall, human ivermectin has a wide range of potential uses, from treating parasitic infections to potentially combating viral diseases. However, it is important to note that the use of ivermectin in humans should always be under the guidance of a healthcare professional, as it can have side effects and interactions with other medications. This comprehensive guide aims to provide an overview of the various uses of human ivermectin, but it is not a substitute for professional medical advice.

What is Human Ivermectin?

Ivermectin is a medication that is primarily used to treat parasitic infections in humans. It belongs to a class of drugs known as antiparasitic agents and is commonly prescribed for conditions such as scabies and certain types of worm infections.

This medication works by killing the parasites or inhibiting their ability to reproduce, thus helping to eliminate the infection. It is available in various formulations, including tablets, creams, and lotions, and is usually taken orally or applied topically to the affected areas of the body.

Human ivermectin has a broad spectrum of activity against a wide range of parasites, including mites, lice, and certain types of worms. It is considered to be a safe and effective treatment option, especially when used as directed by a healthcare professional.

Uses of Human Ivermectin

Human ivermectin is commonly used for the following conditions:

  • Scabies: Ivermectin is often prescribed as a treatment for scabies, a contagious skin condition caused by tiny mites. It helps to kill the mites and relieve the itching and irritation associated with the infection.
  • Intestinal Worm Infections: Certain types of worms, such as roundworms and threadworms, can infect the intestines and cause symptoms like abdominal pain, diarrhea, and weight loss. Ivermectin is used to eliminate these worms and alleviate the associated symptoms.
  • Head Lice: Ivermectin is sometimes recommended as an alternative treatment for head lice infestations that do not respond to other medications. It works by killing the lice and their eggs, helping to eliminate the infestation.

It is important to note that human ivermectin should only be used under the guidance of a healthcare professional. While it is generally well-tolerated, it can cause side effects in some individuals, and its use may be contraindicated in certain medical conditions.

History of Human Ivermectin

Ivermectin is a medication that has been widely used in both veterinary and human medicine since its discovery in the 1970s. It was first developed by Dr. Satoshi Ōmura and Dr. William C. Campbell, who were awarded the Nobel Prize in Physiology or Medicine in 2015 for their discovery.

The story of ivermectin began when Dr. Ōmura, a Japanese microbiologist, collected soil samples from various locations around the world in the hope of finding new microorganisms that could be used to develop new drugs. One of these samples, taken from a golf course in Japan, contained a strain of bacteria called Streptomyces avermitilis.

Dr. Ōmura isolated and cultured the bacteria and found that it produced a compound that showed potent activity against various parasites. This compound was named avermectin, and further research led to the development of a derivative called ivermectin.

In the early 1980s, ivermectin was first used in veterinary medicine to treat various parasitic infections in animals. It quickly became a widely used and highly effective treatment, particularly for diseases caused by roundworms, mites, and lice.

Recognizing its potential for human use, Merck & Co., a pharmaceutical company, conducted clinical trials in the late 1980s to test the safety and efficacy of ivermectin in humans. These trials showed that ivermectin was highly effective in treating several neglected tropical diseases, including onchocerciasis (river blindness) and lymphatic filariasis (elephantiasis).

Since then, ivermectin has been included in the World Health Organization’s List of Essential Medicines, which identifies the most effective and safe medicines needed in a health system. It has been used in mass drug administration programs to control and eliminate these neglected tropical diseases in many countries around the world.

In recent years, there has been growing interest in the potential use of ivermectin for the treatment of other diseases, including certain viral infections. However, further research is needed to fully understand its potential benefits and risks in these contexts.

Medical Uses of Human Ivermectin

Ivermectin is a medication that has a wide range of medical uses in humans. It is primarily used to treat parasitic infections caused by various types of worms and mites. Some of the medical uses of human ivermectin include:

  • Treatment of river blindness (onchocerciasis): Ivermectin is highly effective in treating onchocerciasis, a parasitic infection that affects the skin and eyes. It kills the larvae of the parasitic worm that causes the disease, preventing further damage to the body.
  • Treatment of strongyloidiasis: This parasitic infection is caused by a type of roundworm that lives in the intestines. Ivermectin is commonly used to kill the worms and alleviate the symptoms of the infection.
  • Treatment of scabies: Scabies is a contagious skin condition caused by mites. Ivermectin can be used as an alternative treatment for scabies when topical medications are not effective or well-tolerated.
  • Treatment of head lice: Ivermectin can also be used to treat head lice infestations. It is usually used in combination with other medications to effectively kill the lice and their eggs.
  • Treatment of other parasitic infections: Ivermectin has shown efficacy in treating various other parasitic infections, such as filariasis and strongyloides stercoralis.

It is important to note that the use of human ivermectin should always be done under the supervision of a healthcare professional. The dosage and duration of treatment will vary depending on the specific condition being treated. Additionally, ivermectin should not be used as a preventive measure against parasitic infections unless prescribed by a healthcare provider.

Treatment of Parasitic Infections

Human ivermectin has proven to be highly effective in the treatment of various parasitic infections. It works by targeting the nervous system of parasites, leading to their paralysis and eventual death.

Onchocerciasis (River Blindness)

Ivermectin has been widely used for the treatment of onchocerciasis, also known as river blindness. This disease is caused by the parasitic worm Onchocerca volvulus, which is transmitted through the bites of infected black flies. Ivermectin kills the microfilariae (larvae) of the parasite, preventing them from maturing into adult worms and reducing the severity of symptoms in infected individuals.

Lymphatic Filariasis (Elephantiasis)

Ivermectin is also used in the treatment of lymphatic filariasis, commonly known as elephantiasis. This disease is caused by infection with the filarial worms Wuchereria bancrofti, Brugia malayi, or Brugia timori, which are transmitted by mosquitoes. Ivermectin is effective in killing the microfilariae of these parasites, thereby reducing the progression of the disease and preventing transmission to others.

Note: Ivermectin alone is not curative for lymphatic filariasis, and additional medications, such as albendazole or diethylcarbamazine, may be required for complete treatment.


Scabies is a highly contagious skin condition caused by the infestation of the mite Sarcoptes scabiei. Ivermectin is an effective treatment option for scabies, especially in cases where topical treatments have failed or are impractical. It can be administered orally or topically, depending on the severity of the infestation and the patient’s age.

Caution: Ivermectin should not be used in infants or children weighing less than 15 kg for the treatment of scabies.

Intestinal Parasitic Infections

Ivermectin has also shown efficacy in the treatment of certain intestinal parasitic infections, such as strongyloidiasis and enterobiasis (pinworm infection). It can be administered as a single dose or as a part of a multi-dose regimen, depending on the specific infection.

Disclaimer: The use of ivermectin for the treatment of parasitic infections should always be done under the guidance of a healthcare professional. Self-medication or misuse of the drug can lead to adverse effects and treatment failure.
