What It Is and How It Works
Ivermectin is an antiparasitic medication that works by binding to parts of parasites, leading to their paralysis and eventual death. This action helps clear parasitic infections from the body, effectively treating diseases like river blindness (onchocerciasis) and strongyloidiasis. While the precise mechanism involves disrupting neurological functions in parasites, it is generally safe at prescribed doses for humans.
Indications / Uses
Ivermectin is primarily used to treat parasitic infections. Approved uses include:
- Onchocerciasis: Caused by the worm Onchocerca volvulus, leading to blindness and skin disease if untreated.
- Strongyloidiasis: An intestinal infection caused by a type of roundworm.
- Scabies and lice (topically): Used in topical formulations to treat infestations on the skin.
Off-label, ivermectin has been discussed for COVID-19 treatment, although it is not approved for this use outside of specific studies. Caution and medical supervision are advised.
Dosage Forms and Typical Dosing Considerations
Ivermectin is most commonly available in tablet form for oral administration and as a topical lotion or cream for skin applications. When used orally, dosing is often weight-based, especially in pediatric cases or for specific infections. It’s crucial for dosing to be guided by a healthcare professional, considering factors such as:
- Age and weight
- Specific infection being treated
- Kidney or liver function
- Pregnancy or breastfeeding status
- Other medications
Always follow guidelines from a healthcare provider regarding the correct dosing schedule.
How to Take It Correctly Step-by-Step
- Take orally: Generally taken on an empty stomach with water, usually as a single dosage.
- Timing: Ideally one hour before or two hours after eating.
- If missed dose: Take as soon as you remember, unless closer to the time of the next dose. Do not double up.
- Storage: Keep at room temperature, away from moisture and heat.
Avoid excessive alcohol consumption, and ensure that medical professionals are aware of all medications and supplements you are taking to avoid interactions.
