Fenbendazole, Ivermectin & Cobalt Chloride Bolus

Fenbendazole, Ivermectin & Cobalt Chloride Veterinary Bolus is a combination veterinary formulation intended to support parasite control and nutritional management in livestock, depending on the product's approved composition and target animal species. Fenbendazole is a benzimidazole anthelmintic that works by disrupting parasite microtubule formation and glucose metabolism, helping eliminate susceptible gastrointestinal roundworms and certain other internal parasites. Ivermectin belongs to the macrocyclic lactone class and acts on specific chloride channels in susceptible parasites, helping control certain roundworms and external parasites such as mites and lice. Cobalt chloride provides cobalt, an essential trace element required by ruminants for the production of vitamin B12 by rumen microorganisms; adequate cobalt supports normal metabolism, appetite and growth. The combination may therefore provide complementary antiparasitic activity alongside cobalt supplementation when indicated. However, its precise indications and effectiveness depend on the strengths of the ingredients, animal species and approved product label. The dosage must be determined according to body weight and veterinary instructions, as excessive ivermectin or cobalt intake may cause adverse effects. Special care is required in food-producing animals, including compliance with applicable meat and milk withdrawal periods. The bolus should be administered under veterinary supervision and used according to the manufacturer's approved directions. Before use, check the product label to confirm that the formulation is approved for the particular species and age group, and that it is appropriate for the parasites being targeted. A veterinarian can help assess whether treatment is needed and whether local parasite resistance or the animal's health status may affect the choice of product. Do not use this combination as a substitute for a balanced diet, appropriate herd management, or a diagnosis of other causes of poor appetite or reduced growth. Store and handle the bolus as directed on its packaging, keep it out of reach of children and animals for which it is not intended, and seek veterinary advice promptly if an animal shows an unexpected reaction after administration. Do not repeat treatment or combine it with other antiparasitic or mineral products unless advised by a veterinarian, as this could increase the risk of excessive exposure or other complications.
