Introduction to Albendazole
Albendazole is a powerful, broad-spectrum anthelmintic drug, meaning it fights multiple types of parasitic worm infections.

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.
