Introduction to Ivermectin
.How Ivermectin Works Against Parasites
.Medical Uses of Ivermectin in Humans
Ivermectin is approved for treatment of several parasitic infections, including:
Strongyloidiasis: caused by Strongyloides stercoralis, an intestinal roundworm.
Onchocerciasis (River Blindness): caused by Onchocerca volvulus, transmitted by blackflies.
Scabies and Head Lice: effective against mites (Sarcoptes scabiei) and lice infestations.
Filariasis and Other Parasitic Worms: sometimes used off-label for other infestations

Topical ivermectin formulations are also FDA-approved for rosacea (skin condition) and head lice.
Factors That Affect Ivermectin Dosage
Dosage depends primarily on:
Patient’s body weight
The type and severity of parasitic infection
Immune status of the patient (immunocompromised patients may require repeated doses)
Typical oral dosages:
Onchocerciasis: 150 micrograms/kg once; retreatment may be needed every 3–12 months.
Strongyloidiasis: 200 micrograms/kg as a single dose; stool exam needed for confirmation.
Scabies and head lice: usually a single dose of 200 micrograms/kg; may require repeats in some cases

Pediatric dosing is weight-based with safety established usually above 15 kg body weight
.Administration and Guidelines
Ivermectin tablets are usually taken orally on an empty stomach with a full glass of water, at least 1 hour before or 2 hours after a meal to maximize absorption. Single or multiple doses are based on the infection and treatment plan. Topical forms should be applied as directed to affected skin areas.
.Possible Side Effects and Safety Measures
Common mild side effects include:
Headache, dizziness, muscle aches
Nausea, diarrhea
Mild rash or skin reactions
Serious side effects, though rare, require urgent medical attention and may include:
Severe allergic reactions (hives, difficulty breathing, swelling)
Eye pain or vision changes
Neurological symptoms like confusion, seizures
