Ivermectin is a well-known antiparasitic medication used worldwide to treat various infections caused by parasites, particularly in the skin, intestines, and bloodstream. Originally developed for veterinary use, Ivermectin 6 mg Tablet Dose gained attention in human medicine due to its effectiveness and broad spectrum of activity. In recent years, it has also been discussed in the context of COVID-19, although that application remains controversial.
This article provides a comprehensive overview of ivermectin’s approved uses, recommended dosages, and potential side effects, so you can better understand how this medication works and when it should be used.
What Is Ivermectin?
Ivermectin is an antiparasitic agent derived from avermectin, a compound produced by the bacterium Streptomyces avermitilis. It was approved for human use in the 1980s and is included in the World Health Organization’s List of Essential Medicines due to its importance in treating parasitic diseases in developing countries.

It works by interfering with the nerve and muscle function of parasites, causing paralysis and death. Notably, it does not harm humans at recommended doses because our nervous system is less sensitive to the drug’s mechanism.
Uses of Ivermectin
Ivermectin is primarily used to treat the following parasitic infections:
1. Onchocerciasis (River Blindness)
Caused by the Onchocerca volvulus worm, this condition is transmitted by blackflies and can lead to severe itching and blindness. Ivermectin helps kill the larvae (microfilariae), reducing symptoms and transmission.
2. Strongyloidiasis
This intestinal infection is caused by the Strongyloides stercoralis roundworm. Ivermectin is considered one of the most effective treatments, often requiring just one or two doses.
3. Scabies
A skin condition caused by the Sarcoptes scabiei mite. Ivermectin is used in both topical and oral forms, especially in cases of crusted (severe) scabies or when topical treatments fail.
4. Lice
Head lice and body lice can be treated with oral ivermectin when other topical treatments do not work.
5. Filariasis
Ivermectin plays a role in eliminating Wuchereria bancrofti, one of the worms responsible for lymphatic filariasis, especially in mass drug administration campaigns.
6. Ascariasis and Other Roundworm Infections
Though albendazole is often the first choice, ivermectin is effective against roundworms, whipworms, and certain hookworms.
Off-Label and Controversial Uses
COVID-19
Ivermectin was proposed as a potential treatment for COVID-19 early in the pandemic due to its antiviral properties in lab settings. However, most health organizations, including the WHO, FDA, and CDC, advise against its use for COVID-19, citing insufficient clinical evidence and safety concerns at high doses.
Always consult a healthcare provider before using ivermectin for off-label purposes.

Ivermectin Resistance
In some regions, especially with mass drug administration, there is growing concern about parasite resistance to ivermectin. This emphasizes the importance of proper dosing and only using the medication when needed, under professional guidance.
Ivermectin is a powerful and essential drug in the fight against parasitic infections. Its broad-spectrum activity, oral dosing, and good safety profile make it a first-line treatment for conditions like scabies, strongyloidiasis, and onchocerciasis.
However, like all medications, it must be used responsibly. While ivermectin is effective, it is not a cure-all and should not be taken without proper medical supervision—especially for conditions like COVID-19, where evidence is lacking or conflicting.
If you’re considering ivermectin for any health issue, talk to your doctor to ensure safe and appropriate use.
