Ivermectin for Strongyloidiasis

Ivermectin 200 μg/kg/day for 2 days is the first-line treatment for strongyloidiasis, achieving cure rates of 95–100% — superior to albendazole's 50–80%.

How Ivermectin Treats Strongyloidiasis

Ivermectin binds glutamate-gated chloride channels (GluCl) in Strongyloides stercoralis, causing neuronal hyperpolarisation, paralysis of the worm's pharynx and body wall, and death — acting on both intestinal and skin-migrating larvae.

Clinical Dosing

Standard: 200 μg/kg once daily for 2 days. Hyperinfection: 200 μg/kg daily until negative stool cultures for 2 weeks. Take on empty stomach. Repeat treatment at 2 weeks if follow-up stool is positive.

This is a general reference. Always follow your physician's prescription and current treatment guidelines.

Side Effects

  • Mazzotti-like reaction: fever, itching, rash (immune response to dying larvae)
  • Dizziness and headache
  • Elevated liver enzymes (transient)
  • Hyperinfection syndrome management in immunocompromised (monitor closely)

When to Seek Urgent Care

  • ⚠️Any immunocompromising condition (HIV, corticosteroids, HTLV-1): hyperinfection risk
  • ⚠️Pulmonary symptoms during treatment (hyperinfection)
  • ⚠️Septicaemia (gram-negative bacteraemia from intestinal translocation)
  • ⚠️Neurological symptoms in hyperinfection (meningitis from larval migration)

FAQ: Ivermectin for Strongyloidiasis

Why is ivermectin superior to albendazole for strongyloidiasis?

Ivermectin achieves cure rates of 95–100% for strongyloidiasis vs 50–80% for albendazole. Ivermectin targets both stages of the parasite more effectively. WHO guidelines list ivermectin as the drug of choice.

What is hyperinfection syndrome and why is it dangerous?

In immunocompromised patients, Strongyloides autoinfection can become hyperinfection — massively amplified larval migration causing pneumonitis, meningitis, and gram-negative sepsis as larvae carry gut bacteria through the intestinal wall. Mortality is high without prompt treatment.

How do we know strongyloidiasis is cured after ivermectin?

Follow-up stool microscopy and Strongyloides serology at 3 and 6 months post-treatment. Serology titres should decline. For immunocompromised patients, more frequent follow-up is needed due to higher recurrence risk.
