Panacur Powerpac (fenbendazole paste) provides larvicidal killing action for optimum parasite control. It has a high degree of efficacy against the predominant internal parasites in horses−large and small strongyles including larval stages, pinworms, and ascarids−for most effective treatment. For best results, use in all newly arrived horses and then once or twice per year. Convenient, oral administration and unique apple-cinnamon flavor make it easy to administer. Powerpac (5 x 57-gram syringes) offers a complete course of treatment for a 1250-lb. horse.
