Quick Facts Scannable
- Ivermectin and moxidectin are antiparasitic medications.
- Both medications are used to treat a variety of parasitic infections.
- Ivermectin is commonly used in both humans and animals.
- Moxidectin is primarily used in veterinary settings but also approved for certain human uses.

What It Is and How It Works
Ivermectin and moxidectin belong to a class of drugs known as macrocyclic lactones. They exert their effects by binding to specific chloride channels in the nerve and muscle cells of parasites, leading to increased permeability of the cell membrane to chloride ions. This results in paralysis and death of the parasite.
Ivermectin primarily targets ectoparasites like mites and endoparasites such as nematodes. Moxidectin works similarly, with potency against a range of parasites, particularly those resistant to other treatments.
Indications / Uses
Ivermectin is approved for use in treating various parasitic infections in humans, such as onchocerciasis (river blindness) and strongyloidiasis. It\’s also used off-label for conditions like head lice and scabies. In veterinary medicine, it\’s effective for treating a range of internal and external parasites.
Moxidectin is mainly used in veterinary settings for controlling parasites in livestock and pets. It has been approved for human use in certain regions for treating river blindness.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in oral tablet form, topical creams, and injections. Moxidectin is commonly found in oral pastes, gels, pour-ons, and injectables for veterinary use.
Dosing considerations depend on the species, type of infection, and individual health factors such as age, weight, and liver or kidney function. It\’s crucial that dosing be determined by a healthcare provider to ensure safety and efficacy.
How to Take It Correctly Step-by-Step
- Follow prescription instructions carefully as directed by a healthcare professional.
