What It Is and How It Works
Ivermectin is an antiparasitic medication that has been used for decades to treat a variety of infections caused by parasites, especially in tropical areas. It works by binding to components within the parasites, which leads to increased permeability of their cell membranes. This results in paralysis and death of the parasites or a slow down in their growth, effectively helping to eliminate the infection.
Originally developed for veterinary use, ivermectin was later approved for human use, demonstrating significant efficacy against conditions like river blindness (onchocerciasis) and intestinal strongyloidiasis.
Indications / Uses
Primarily, ivermectin is used for the treatment of:
- River blindness (onchocerciasis) – a disease caused by infection with the parasite Onchocerca volvulus.
- Intestinal strongyloidiasis – an infection caused by the roundworm Strongyloides stercoralis.
It also has off-label uses based on clinician discretion, but these should be guided by current evidence and regional guidelines. It\’s vital to note that any off-label use should only be pursued under professional medical supervision.
Dosage Forms and Typical Dosing Considerations
Ivermectin is commonly available in tablet form for human use. The dosing of ivermectin is dependent on several factors including the type and severity of the infection, the patient\’s weight, and their overall health condition. It is crucial to follow the prescribed instructions by a healthcare provider.
Dosing adjustments may be necessary for patients with liver impairment or other health conditions. As with all medications, it is important for pregnant or breastfeeding women to consult with a healthcare provider before starting ivermectin.
How to Take It Correctly Step-by-Step
When taking ivermectin, consider the following steps:
- Take the tablet on an empty stomach with a full glass of water unless instructed otherwise by your doctor.
- Avoid consuming alcohol during treatment.
