Albendazole, which is known more commonly as its brand name, Albenza, is an anthelmintic (anti-worm) medication. We have Albendazole available in 200mg and 400mg tablets (white in color) for administration.

This medication is taken to help treat infections caused by worms as well as preventing worms from hatching and multiplying in your body. There are quite a few different worms that Albendazole can help get rid of, such as giardiasis, trichuriasis, filariasis, neurocysticercosis, hydatid disease, pinworm disease, and ascariasis. Two examples of infections that Albendazole treats include neurocysticercosis (an infection of the nervous system caused by pork tapeworms) and cystic hydatid disease of the liver, lung, and peritoneum (infections caused by dog tapeworms). Albendazole works by cutting off the worms’ supply of glucose (sugar) so they can no longer absorb it causing them to eventually lose energy and die.

Always follow directions given to you by your doctor.
