What parasites are killed by albendazole?

Introduction to Albendazole

Albendazole is a powerful, broad-spectrum anthelmintic drug, meaning it fights multiple types of parasitic worm infections. First developed in the 1970s and on the World Health Organization's List of Essential Medicines, albendazole online is widely used worldwide to treat parasitic infections in both humans and animals.

The full list of worms and parasites targeted by albendazole, its uses, how it works, and safety tips.

How Albendazole Works in the Body?

Albendazole interferes with the parasites ability to absorb glucose. This energy loss causes the parasite to become immobilized and die. It works at both the intestinal and tissue levels, making it ideal for a wide variety of infections.

Types of Parasites Killed by Albendazole

Albendazole is effective against a wide range of helminths (worms) and some protozoa. These parasites are generally grouped into:

  • Nematodes (roundworms)

  • Cestodes (tapeworms)

  • Trematodes (flukes) to a limited extent

  • Protozoa (indirectly or off-label)

Tissue Parasites Targeted by Albendazole

Albendazole is also used for more serious internal infections involving tissue or organs:

  • Neurocysticercosis: Caused by Taenia solium larvae (brain involvement)

  • Echinococcosis (Hydatid disease): Caused by Echinococcus granulosus and E. multilocularis

These infections are more difficult to treat and usually require long-term albendazole therapy (up to several months).

Albendazole vs. Other Anthelmintics

Compared to drugs like:

  • Mebendazole: Similar spectrum, but albendazole is more effective against tissue parasites

  • Ivermectin: Often better for Strongyloides and scabies

  • Praziquantel: Preferred for fluke and schistosome infections

Albendazole stands out as a versatile first-line therapy for many helminths.

Albendazole for Rare and Off-label Uses

In some cases, albendazole is used off-label or in combination therapy for:

  • Trichinellosis (Trichinella spiralis)

  • Toxocariasis (Toxocara canis)

  • Gnathostomiasis

  • Cutaneous larva migrans (creeping eruption)

Consult your doctor for these rarer conditions.

Duration of Treatment

Most intestinal infections require a single dose or a short course. More serious infections like echinococcosis or neurocysticercosis require repeated cycles over months, often in combination with steroids.

Albendazole in Children and Adults

ABD 400mg is safe for use in children over 1 year of age. However, dosages may vary based on body weight and severity of infection.

Effectiveness and Cure Rates

  • Single-dose cure rate: Up to 95% for pinworms and roundworms

  • Tissue infections: Varying success, often requires imaging follow-up

  • Decrease in abdominal pain

  • Improved appetite

  • Normal bowel movements

  • Dead worms in stool (not always visible)

Side Effects

Common side effects:

  • Nausea

  • Dizziness

  • Mild abdominal discomfort

Rare but serious:

  • Liver inflammation

  • Bone marrow suppression

Regular liver function tests may be needed during long-term use.

Contraindications and Drug Interactions

Avoid albendazole if:

  • You're pregnant (especially 1st trimester)

  • You have liver disease

  • You're taking cimetidine, dexamethasone, or anti-seizure meds

Patients report high satisfaction with common intestinal worms. For complex infections like hydatid disease, success often depends on early detection and continuous treatment.
