- Commonly prescribed for hydatid disease and neurocysticercosis.
- Typically available in tablet form.

What it Is and How It Works
Albendazole is an anthelmintic, which means it is used to expel parasitic worms from the body. It works by inhibiting the parasites\’ ability to absorb sugars (glucose), which they need for survival. Without glucose, the parasite cannot generate energy, eventually leading to its death and expulsion from the body. This makes albendazole effective in treating various worm infections.
Indications / Uses
Albendazole is primarily used to treat the following conditions:
- Hydatid Disease: Caused by the larvae of the dog tapeworm, this condition affects the liver, lungs, and other organs.
- Neurocysticercosis: Infection of the brain, muscle, and other tissues by cysts of the pork tapeworm.
Additionally, albendazole may be prescribed off-label for other types of parasitic infections at the discretion of a healthcare provider.
Dosage Forms and Typical Dosing Considerations
Albendazole is commonly available in a tablet form that can be taken orally. The dosage and duration of treatment depend on the specific infection being treated and factors such as patient age and overall health. Pediatric dosing, as well as dosing for individuals with liver or kidney impairment, requires careful consideration and should be guided by a healthcare professional.
How to Take It Correctly Step-by-Step
- Follow the instructions given by your healthcare provider.
- Take the tablet with food to enhance absorption.
- If a dose is missed, take it as soon as you remember, but skip it if it\’s near the next dose time.
- Complete the full course of treatment even if symptoms improve.
- Store albendazole at room temperature, away from excess heat and moisture.
