Ivermectin 40mg Tablets are a high-dose antiparasitic medication, used to treat serious or widespread parasitic infections. This dose is not commonly used and should be taken only under strict medical supervision.

What is Ivermectin 40mg Used For?

This high-strength dose may be prescribed in special cases such as:

• Severe scabies (especially crusted scabies)
• Strongyloidiasis (intestinal parasite)
• Onchocerciasis (river blindness)
• Lymphatic filariasis
• Head lice (if resistant to topical treatment)
• Off-label use in viral infections (e.g., COVID-19) – only under professional guidance

How It Works

Ivermectin interferes with the parasite’s nervous system, causing paralysis and death. It allows the body to eliminate the infection effectively.

Dosage Guidelines

• The standard Ivermectin dose is 200 micrograms per kg of body weight.
• A 40mg tablet may be appropriate for individuals over 100–120 kg or for multiple-dose regimens (e.g., crusted scabies).
• Usually taken once and sometimes repeated after 7–14 days depending on condition.

Must be prescribed by a doctor. High doses increase the risk of side effects.
