What It Is and How It Works
Ivermectin is an antiparasitic medication belonging to the avermectin family. It works by binding to glutamate-gated chloride channels specific to invertebrates, which leads to increased permeability of the cell membrane to chloride ions, resulting in paralysis and death of the parasite. While its action is effective against many parasites, it primarily targets helminths and arthropods, and its mechanism provides no effect on humans at therapeutic doses.
Indications / Uses
Approved uses for ivermectin include the treatment of various parasitic infestations, such as:
- Onchocerciasis (river blindness): Caused by the parasite Onchocerca volvulus.
- Intestinal Strongyloidiasis: Caused by the nematode Strongyloides stercoralis.
- Other parasitic infections as deemed appropriate by a healthcare provider.
Off-label uses have been speculated, but readers are urged to only use ivermectin in these situations under strict medical supervision as evidence varies and can be controversial.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in the following human dosage forms:
- Oral tablets: Commonly used for systemic infections.
- Topical formulations: Used for skin conditions like rosacea.
Typical dosing considerations depend on the specific condition being treated, the patient’s weight, and other health considerations. Special care is needed for dosing in populations such as children, pregnant or breastfeeding women, the elderly, and those with liver or kidney concerns. It is imperative to follow the healthcare provider’s instructions closely.
