Albendazole is used to treat neurocysticercosis (infection caused by the pork tapeworm in the muscles, brain, and eyes that may cause seizures, brain swelling, and vision problems). Albendazole is also used along with surgery to treat cystic hydatid disease (infection caused by the dog tapeworm in the liver, lung, and lining of the abdomen that may damage these organs). Albendazole is in a class of medications called antihelmintics. It works by killing the worms.

Albendazole comes as a tablet to take by mouth. It is usually taken with food twice a day. When albendazole is used to treat neurocysticercosis, it is usually taken for 8 to 30 days. When albendazole is used to treat cystic hydatid disease, it is usually taken for 28 days, followed by a 14-day break, and repeated for a total of three cycles. Take albendazole at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take albendazole exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

If you are giving the medication to a child or if you cannot swallow the tablets whole, you may crush or chew the tablets and swallow the medication with a drink of water.

Take albendazole until you finish the prescription, even if you feel better. If you stop taking albendazole too soon or skip doses, your infection may not be completely treated.

Albendazole is also sometimes used to treat infections caused by roundworms, hookworms, threadworm, whipworm, pinworm, flukes, and other parasites (a plant or animal that lives within another living organism to receive some benefit). Talk to your doctor about the risks of using this medication for your condition.

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
