Fenbendazole for cats and Dogs

Most shelter workers have heard of the magic known as fenbendazole – is one of my favorite antiparasitic-and is a great drug for many reasons. It is generally considered a safe drug, toxicity occurs only in overdose 100x and exotic species. Fenbendazole is not systemically absorbed and more than 50% out of the animal feces. It should be administered for at least 3 days to kill parasites, as it has to stop cell division for some time before it becomes fatal to the parasite. 

Fenbendazole is labeled for use in cows, horses, pigs and dogs; but it has also been used in cats, sheep, birds, reptiles and fish. It is marked to kill roundworms, hookworms, whipworms and tapeworms some, but is not effective against the most common tapeworms, and therefore should not be relied upon to kill the tapes. increased use of fenbendazole in shelters is to kill whipworms, Giardia, and lungworms.

Fun fact: In the treatment of whipworm (Trichuris Vulpis) You may have heard of the rule of 3, try for three days, then repeat a course of three days in three weeks and again at three months. It is an easy treatment regimen and commonly recited, but did you know there is actually a scientific reason not to try this way know? Whipworm takes 3 months to mature from an egg to an adult. If you kill adults on day 1, then three weeks later there will be some immature adults who have matured, but you still have eggs and larvae of worms present. Wait up to 3 months and then try again, and do not bother with the treatment of three weeks.

Fenbendazole (carbamate 5-phenyl-thio-2-benzimidazole) has a broad spectrum of effects and cestocidal nematocides, is active against adult forms, larvae and eggs of gastrointestinal and lung and cestode parasites in animals. 
The mechanism of action of fenbendazole is the destruction of microtubules in cells of intestinal worms and disruption of energy processes, leading to the death of the parasites. 
When administered orally, fenbendazole is easily absorbed in the intestine and is distributed in organs and tissues of the animal; excreted from the body in unaltered form and as metabolites, mainly in the bile and urine partially in animals also varnished milk.
