How It Works

Albendazole kills both immature worms and adult pinworms.

Why It Is Used

Albendazole is used for infections caused by parasites. Albendazole may be used in cases of pinworm infections that cannot be treated with other pinworm medicines. It is not the medicine usually first used to treat pinworm infections.

Albendazole is not recommended for use in pregnant women or in people with poorly functioning livers.

How Well It Works

In most cases, albendazole gets rid of pinworm infection.

This medicine may be used in special cases of pinworm infection where the person cannot be treated with other pinworm medicines, such as when a person has side effects from other medicines.
