- Works by paralyzing and killing parasites.
- Available in oral and topical forms.
- Commonly used for conditions like river blindness and scabies.
- May cause side effects such as nausea and dizziness.

What It Is and How It Works
Ivermectin belongs to a class of drugs known as antiparasitics. At a high level, it works by binding to certain chloride channels found in parasite nerve and muscle cells, which increases the permeability of cell membranes and results in paralysis and death of the parasites.
In technical terms, ivermectin binds selectively and with high avidity to glutamate-gated chloride ion channels, which are critical for the neurotransmission of many parasites. By doing so, it disrupts nerve impulses, leading to death of the parasite.
Indications / Uses
The primary approved uses for ivermectin include the treatment of various parasitic infections such as:
- Onchocerciasis (river blindness)
- Strongyloidiasis (intestinal threadworm infection)
- Pediculosis (lice)
- Certain types of scabies
While some studies have explored off-label uses, such as potential antiviral effects, it remains crucial that these are approached under professional supervision.
Dosage Forms and Typical Dosing Considerations
Ivermectin is typically available in oral tablet and topical cream or lotion forms. The dosing can depend on factors like the type of infection being treated, patient age, weight, and general health. It\’s crucial for dosing to be determined by healthcare professionals based on individual patient needs and conditions.
Dosing may be adjusted for those with liver function impairments or when used in conjunction with other medications that might affect how ivermectin is metabolized.
