What It Is and How It Works
Ivermectin is an antiparasitic medication primarily used to treat infections caused by certain parasites. It works by interfering with the nerve and muscle function of parasites, ultimately resulting in their paralysis and death. In more technical terms, ivermectin binds with high affinity to glutamate-gated chloride ion channels, which are critical to the functioning of invertebrate nerve and muscle cells. This action increases the permeability of the cell membrane to chloride ions, with hyperpolarization occurring and resulting in paralysis and death of the parasite.
Indications / Uses
Ivermectin is widely used for the treatment of various parasitic infections. These include:
- Onchocerciasis: Also known as river blindness, a disease caused by the parasite Onchocerca volvulus.
- Strongyloidiasis: Infection with the roundworm Strongyloides stercoralis.
- Scabies: A skin infestation caused by the mite Sarcoptes scabiei.
- Pediculosis: Commonly known as lice infestations.
Off-label uses may exist but should only be pursued under medical guidance. Ivermectin’s use in other conditions should be supported by substantial clinical evidence and monitored by a healthcare professional.
Dosage Forms and Typical Dosing Considerations
Ivermectin is most commonly available in oral tablet form and as a topical cream. Dosage considerations are influenced by factors including the type of infection treated, patient weight, age, and additional medical conditions. Here are some general principles:
- Age and weight: Dosing for pediatric patients typically requires adjustments based on weight; never self-prescribe for young children.
- Comorbidities: Conditions such as liver or kidney disease may necessitate dosing adjustments.
- Pregnancy/Breastfeeding: Consult a healthcare provider, as safety data are limited in these populations.
Always follow specific dosing instructions provided by your healthcare provider or pharmacist.
