Fenbendazole

medicationWhy has my veterinarian prescribed this medicine?

Fenbendazole is used to control roundworms in dogs, cats and rabbits and some types of tapeworms in dogs and cats. Your veterinarian surgeon may prescribe fenbendazole for a pregnant dog to reduce the chance of the puppies being born with worms. Your veterinarian will advise a deworming programme for your pet.

Fenbendazole is also used for treatment of giardiosis, which is characterised by diarrhoea in dogs and cats. Giardiosis can potentially be transmitted to humans and your veterinarian will advise you on precautions to take.

Fenbendazole also helps control the intracellular parasite Encephalitozoon cuniculi, which can cause nervous signs, urinary incontinence, eye problems and death in rabbits. The parasite is transmitted via urine-contaminated food and/or water and measures should be taken to ensure that food and water are placed so as to prevent soiling.

How does this medicine work?

Fenbendazole interrupts parasite energy metabolism by binding to tubulin, thereby disrupting microtubular cell structure and preventing nutrient uptake and other functions.
