What It Is and How It Works
Ivermectin is an antiparasitic agent that belongs to the class of drugs known as avermectins. It works by binding to the glutamate-gated chloride channels in nerve and muscle cells of parasites, causing increased permeability to chloride ions, leading to paralysis and death of the parasite. This makes it effective for treating infections caused by specific parasites.
Primarily used for treating helminthic and some insect-related conditions, its specificity for parasite receptors is what makes it safe and effective for humans at prescribed dosages.
Indications / Uses
Ivermectin is primarily approved for treating several parasitic infections. In humans, it is most commonly used for:
- Onchocerciasis: Also known as river blindness, a disease caused by the parasitic worm Onchocerca volvulus.
- Strongyloidiasis: An infection by the roundworm Strongyloides stercoralis.
- Scabies: A contagious skin condition caused by mites.
- Lice infestations: As a topical treatment for head lice.
Its use in other contexts, such as COVID-19, is not widely recommended due to insufficient scientific evidence and varies by country/regulatory guidelines.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in various formulations, including:
- Oral Tablets: Commonly used for most human applications.
- Topical Cream and Lotion: Mainly for the treatment of skin infections like scabies or head lice.
The dosage of Ivermectin depends on several factors including the type and severity of infection, patient weight, and medical history. It’s essential that individuals follow the prescription provided by their healthcare provider. Adjustments may be needed for patients with liver impairment or those taking other medications.
How to Take It Correctly Step-by-Step
- Follow the Prescription: Use exactly as prescribed. Do not take in larger or smaller amounts or for longer than recommended.
- With or Without Food: While it might be taken with a meal to help improve absorption and decrease gastrointestinal upset, it’s advised to follow specific guidance provided by a healthcare provider.
- Missed Dose: Take the missed dose as soon as possible unless it is almost time for the next dose. Do not take extra medicine to make up for a missed dose.
- Storage: Store at room temperature away from moisture and heat. Keep out of reach of children.
- Avoid Common Mistakes: Do not double dose, share medication, or mix with alcohol without professional advice.
