What It Is and How It Works
Ivermectin is a medication classified as an antiparasitic. It is used to treat a variety of parasitic infections by targeting the nerve and muscle cells of parasites, leading to paralysis and death of the parasite. It mainly influences chloride channels, opening them and hyperpolarizing neurons and muscles of parasites, making it effective in controlling diseases caused by roundworms, mites, and lice. Notably, ivermectin does not typically exhibit the same effects in humans at therapeutic doses due to a higher affinity for parasite-specific targets.
Indications / Uses
Ivermectin is primarily indicated for the treatment of certain parasitic infections. These include:
- Onchocerciasis: Widely known as river blindness, caused by Onchocerca volvulus.
- Lymphatic Filariasis: Known as elephantiasis, is caused by the nematodes Wuchereria bancrofti and others.
- Strongyloidiasis: An intestinal infection caused by the roundworm Strongyloides stercoralis.
Off-label applications have been explored, particularly its potential use for treating scabies, head lice, and as an adjunct in treating rosacea. It is essential that these off-label uses are only considered under the stewardship of a healthcare provider.
Dosage Forms and Typical Dosing Considerations
Ivermectin is commonly prescribed in tablet form. The dosing depends on the indication, the patient\’s weight, and the formulation. Dosing must consider liver function and concurrent medications that may influence the metabolism of ivermectin. Generally, it is dosed according to body weight in a single administration. Special populations such as the elderly, or those with liver impairments, may require adjusted dosing.
How to Take It Correctly Step-by-Step
- Follow the prescription directions precisely as provided by your healthcare provider.
- Usually taken on an empty stomach with water.
- Missed doses should be taken as soon as remembered unless close to the time of the next dose.
- Store ivermectin at room temperature away from excess heat and moisture.
- Avoid doubling up on doses if a dose is missed, unless advised by your physician.
- Avoid alcohol as it could amplify side effects like dizziness.
