What It Is and How It Works
Ivermectin belongs to a class of drugs known as antiparasitics. It works by binding to specific proteins in parasites, leading to an increase in the permeability of the cell membrane to chloride ions, which in turn paralyzes and eventually kills the parasite. This allows the body\’s immune system to eliminate the infection.
Indications / Uses
Ivermectin is primarily approved for the treatment of parasitic infections, including:
- Onchocerciasis (River Blindness): An infection caused by a worm that leads to severe itching and potentially blindness.
- Strongyloidiasis: An intestinal infection caused by a type of roundworm.
- Scabies: A skin infection caused by tiny mites.
While some have discussed its off-label use in treating COVID-19, this remains a controversial and highly debated topic within the medical community, with major health organizations advising against its use for this purpose outside clinical trials.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms, including oral tablets and topical formulations. The dosing will depend on the specific indication, patient\’s weight, and clinician\’s discretion. The standard dosing for parasitic infections like strongyloidiasis is often a single oral dose based on body weight, while topical applications may be used for skin conditions.
It\’s essential to follow the dosing prescribed by a healthcare provider, as factors such as liver function and concomitant medications can influence the appropriate dosing strategy.
How to Take It Correctly Step-by-Step
For oral intake, ivermectin is usually taken on an empty stomach with water. Here are general instructions:
- Follow the prescription label carefully.
- Take it on an empty stomach (usually one hour before breakfast) with a full glass of water.
- If you miss a dose, take it as soon as possible. If it\’s close to the next dose, skip the missed dose; do not double up.
