Introduction of Ivermectin Dosage
Ivermectin is one of the most widely used antiparasitic medicines in the world. Originally developed for veterinary use, it has been approved by the FDA for several human parasitic conditions and is prescribed by doctors across the USA and globally. If you are considering ivermectin for a diagnosed parasitic infection, understanding the correct dosage is essential — taking too little may be ineffective, and taking too much can be harmful.
At TheMedicineKart, we stock genuine generic ivermectin in multiple strengths including 6mg, 12mg, 15mg, 20mg, and 40mg tablets, all sourced from WHO-GMP certified manufacturers.
What is Ivermectin Used For?
Ivermectin is an antiparasitic medication approved for use in humans for the following conditions:
- Onchocerciasis (River Blindness) — caused by the parasitic worm Onchocerca volvulus
- Strongyloidiasis — an intestinal roundworm infection
- Lymphatic Filariasis — a tropical disease affecting the lymphatic system
- Scabies — a highly contagious skin condition caused by mites
- Head Lice — as a topical or oral treatment option
It works by binding to nerve and muscle cells of parasites, causing paralysis and death of the organism. It does not harm human cells at the doses used for treatment.
If you are treating any of the above conditions, visit our Anti Worm category to browse all available strengths.
Ivermectin Dosage Guide by Weight
Ivermectin dosage is always calculated based on body weight. The standard recommended dose for most parasitic infections is 150–200 mcg per kilogram of body weight, taken as a single oral dose.
Body Weight | Standard Dose (150 mcg/kg) | Tablet Strength |
15–24 kg | 3 mg | 6 mg (half tablet) |
25–35 kg | 6 mg | 6 mg |
36–50 kg | 9 mg | 6 mg + 3 mg |
51–65 kg | 12 mg | 12 mg |
66–79 kg | 15 mg | 15 mg |
80–100 kg | 18–20 mg | 20 mg |
Over 100 kg | 24–40 mg | 24 mg or 40 mg |
