What It Is and How It Works
Ivermectin belongs to a class of drugs known as anthelmintics, which are used to treat parasitic worm infections. It works by binding to the parasites\’ nerve and muscle cells, leading to paralysis and death. This mechanism eliminates the parasites from the body and prevents further infection. While originally used only in veterinary medicine, ivermectin has become an important treatment for certain parasitic diseases in humans.
Indications / Uses
Ivermectin is primarily approved for treating infections caused by particular parasitic worms. These include:
- Onchocerciasis (River Blindness): Affects the skin and eyes and is caused by the parasitic worm Onchocerca volvulus.
- Intestinal Strongyloidiasis: An infection caused by the nematode Strongyloides stercoralis.
Off-label uses have emerged, but they should only be pursued under the supervision of a healthcare professional. The evidence for some off-label uses varies, and more research is needed to confirm their efficacy.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available primarily in oral tablet form for human use. The dosing of ivermectin can vary depending on the infection being treated, the patient\’s weight, and their overall health:
- Doses are typically calculated based on body weight.
- Special considerations may apply for individuals with liver or renal impairments, or if the patient is pregnant or breastfeeding.
- Always follow your healthcare provider’s instructions regarding dosage and duration.
How to Take It Correctly Step-by-Step
- Take ivermectin on an empty stomach, with a full glass of water.
- If you miss a dose, take it as soon as you remember unless it\’s almost time for the next dose. In that case, skip the missed dose. Do not double doses.
- Store at room temperature away from moisture and heat.
- Avoid alcohol while taking ivermectin, as it can exacerbate side effects.
