What It Is and How It Works
Ivermectin is an antiparasitic medication that works by binding to certain proteins in the nerve and muscle cells of parasites. This action causes paralysis and subsequent death of the parasite, helping to clear the infection. It is used for both human and veterinary purposes, although formulations and dosages differ significantly between these applications.
Indications / Uses
Ivermectin is approved for the treatment of several parasitic infections in humans, such as onchocerciasis (river blindness), strongyloidiasis, and other conditions caused by hookworm or roundworms. Additionally, it is used topically for the treatment of head lice and rosacea. Off-label uses include other parasitic infestations, but these should only be pursued under professional supervision.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in oral tablet form, usually taken as a single dose on an empty stomach with water. Topical formulations are used for skin conditions like lice and rosacea. The appropriate dosing of ivermectin depends on a variety of factors including age, weight, the specific infection being treated, and liver or kidney function. It is essential that dosing instructions provided by a healthcare provider are followed accurately.
How to Take It Correctly Step-by-Step
To ensure the effective and safe use of ivermectin:
- Take the oral version as a single dose on an empty stomach with a full glass of water.
- Do not split, chew, or crush tablets unless instructed by a healthcare provider.
- For missed doses, take it as soon as possible unless it’s close to the next scheduled dose. In that case, skip the missed dose.
- Store ivermectin in a cool, dry place away from sunlight.
- Do not share your medication with others.
