What It Is and How It Works
Ivermectin is an antiparasitic drug that works by interfering with the nerve and muscle functions of the parasites, ultimately leading to their paralysis and death. Its primary action is against the nervous system of parasites, making it effective in treating infections caused by several parasitic worms.
Although its use for other viral infections is a topic of ongoing research, current evidence does not robustly support such uses outside supervised clinical settings.
Indications / Uses
Approved uses of ivermectin tablets for humans include the treatment of:
- Strongyloidiasis: An intestinal infection caused by the parasitic worm Strongyloides stercoralis.
- Onchocerciasis: Also known as river blindness, caused by the worm Onchocerca volvulus.
While ivermectin is researched for other uses, any off-label use should only occur under strict supervision from qualified healthcare professionals.
Dosage Forms and Typical Dosing Considerations
Ivermectin is commonly available in tablet form for oral administration in humans. The dose depends on various factors, including the patient\’s weight, the specific parasitic infection being treated, and other individual health considerations. Special populations, such as those with liver or kidney impairment, may require adjusted dosing and thorough monitoring.
Always follow the prescription label or the guidance provided by a healthcare provider.
How to Take It Correctly Step-by-Step
When taking ivermectin:
- Take the medication on an empty stomach, at least one hour before breakfast.
