What It Is and How It Works
Ivermectin is an antiparasitic medication that works by interfering with the nerve and muscle functions of parasites, causing their paralysis and death. It binds to specific sites inside the parasites, leading to an increase in the permeability of the cell membrane within these organisms. As a result, neurotransmitter signals are blocked, effectively eliminating the parasite from the host.
Indications / Uses
Ivermectin is primarily used to treat infections caused by certain parasites. Approved uses include:
- Onchocerciasis: Caused by the parasitic worm Onchocerca volvulus, leading to skin and eye problems.
- Intestinal strongyloidiasis: An infection caused by the roundworm Strongyloides stercoralis.
Though ivermectin has been considered for off-label uses, including as a potential COVID-19 treatment, this is not universally approved and should only be pursued under professional guidance and clinical settings.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in oral tablet form and sometimes as a topical preparation, such as creams or lotions for external usage. Dosing varies based on the condition treated and patient specifics such as age, weight, kidney and liver function, and any coexisting health conditions. It\’s crucial that patients follow their prescriptions accurately, as dosage adjustments should only be made by healthcare professionals.
How to Take It Correctly Step-by-Step
When taking oral ivermectin, it should generally be taken on an empty stomach with water. Follow your healthcare provider’s instructions regarding the timing and frequency of your dose. If you miss a dose, take it as soon as you remember, but do not double up on doses. It\’s important to store ivermectin at room temperature away from light and moisture.
Common mistakes include skipping doses, taking the medication incorrectly regarding food, or self-medicating without guidance.
