Fenben powder is used to treat various worms and parasites in livestock and pets. It is particularly effective in treating nematodes(both mature and immature forms), some types of cestodes, and trematodes. It is a homogeneous powder of white or gray color with specific odor, insoluble in water.

In some cases, your veterinarian may prescribe a compounded formulation of fenbendazole. Compounded medications are made by veterinarians or licensed pharmacists on an individual basis to best suit a pet’s unique health needs, such as if they can’t take an FDA-approved medication due to allergies or if the dosage strength of a commercially available drug isn’t appropriate for their weight.

Monitor your pet closely after receiving this medication. Your vet will likely recommend routine fecal exams to ensure that all internal parasites have been killed, and to determine whether additional doses of fenbendazole are needed. Fenbendazole is moderate-acting and should stop working within a few days, although the effects can last longer in pets with liver or kidney disease. fenben powder
