What is albendazole for cats?

Albendazole for cats is a product with an antiparasitic effect. It belongs to the chemical class of benzimidazoles. These are organic compounds which are traded under better-known dewormers such as febantel or fenbendazole. These are also used against internal parasites. These are products that have been used since the 1960s, although albendazole, only began to be administered in the 70s.

The first benzimidazoles had an effect against adults and larvae of gastro-intestinal worms. The latter broadened the spectrum. Some, including the albendazole detailed in this article, manage to pass from the intestine into the blood. This means they can also eliminate worms outside the digestive system, such as those that lodge in the lungs or heart.

Albendazole is both an anthelmintic and antiprotozoal drug. This means it acts on parasitic worms and protozoa, respectively. This means they can be effective on nematodes, cestodes or tapeworms, as well as trematodes and giardia. All of these are internal parasites that lodge themselves in the digestive system. Some specific types of internal parasites in cats such as Toxocara spp., Ancylostoma spp. or Trichuris spp. and be treated with albendazole.

The specific action of albendazole is the prevention of digestive enzyme function in these types of parasites. Since they cannot metabolize the glucose they need for maintaining life, they will die as a result.

Albendazole for cats uses

The main use of albendazole is the internal deworming of cats. Establishing both an external and internal preventive deworming schedule for cats is a core responsibility of cat guardianship. It helps protect the cats from potentially life threatening illnesses caused by various types of parasites. Even if they live in a home without access to the outside, cats can become infested due to parasites entering the home from various sources.

Unfortunately, albendazole for cats does not have a residual effect. This means it is not a good deworming agent for preventive purposes in cats. For preventive deworming, you will need to speak to a veterinarian who will be able to establish the correct deworming agent for both your cat's specific needs and those of the region in which you live. Generally speaking, a deworming schedule for cats will need to be updated every 3-4 months.

Although not a good preventive dewormer, albendazole is very effective at killing various parasites after an infestation. We may see the symptoms of a parasitical infestation due to the cat vomiting and having diarrhea, among many other symptoms. In many cases, the process may be asymptomatic. It will only be once we go to a veterinarian for examination can we confirm the type of parasite. If the parasite is one which can be killed with albendazole, it is possible the veterinarian will prescribe this drug for your cat.

Albendazole for cats dosage

Albendazole can be found in the following preparations:

  • Oral tablets
  • Oral liquid suspension

The preparation of albendazole used for your cat will be determined by the veterinarian. Generally speaking, young kittens will be given the drug in oral suspension with the use of a syringe. Adults may be given tablets. Both forms of albendazole should be given with food as it allows for better absorption of the drug. Learn more with our article on how to give a pill to a cat.

The dose will depend on the format of the drug and the parasite to be eliminated. Some presentations come in a syringe pre-dosed by weight. It is very important to weigh the cat so that the dose of albendazole is both appropriate and effective. Some albendazole can be given in droppers, making it easy to dose and add to food or water.

Depending on each case, the dose can be single or repeated for several days in a row. This is usually around 5 days. It may also be necessary to do more than one deworming as its efficacy can be better with multiple doses. Our vet will tell us the guideline to follow.
