Special precautions for use Assess body weight as accurately as possible before calculating the dosage. Operator warnings Direct contact with the skin should be kept to a minimum. Wear impermeable rubber gloves and wash hands after use. The use of this product should be based on local epidemiological information about susceptibility of the nematodes and recommendations on how to limit further selection for resistance to anthelmintics. Adverse Reactions Gastrointestinal signs (such as vomiting and diarrhoea) can occur in very rare cases in the dogs and cats. The frequency of adverse reaction is defined using the following convention: - very common (more than 1 in 10 animals displaying adverse reactions during the course of one treatment) - common (more than 1 but less than 10 animals in 100 animals) - uncommon (more than 1 but less than 10 animals in 1,000 animals) - rare (more than 1 but less than 10 animals in 10,000 animals) - very rare (less than 1 animal in 10,000 animals, including isolated reports). Use during pregnancy or lactation The product can be used in pregnant bitches. As teratogenic effects in dogs and cats cannot be completely ruled out in very rare cases, the treatment in the first two trimesters of pregnancy should be based on the benefit-risk evaluation by the responsible veterinary surgeon. Interactions None known. Amounts to be administered and administration route Shake container before use. Routine treatment of adult dogs and cats 1 ml per 1 kg body weight as a single oral dose. (= 100 mg fenbendazole/kg body weight) Practical dosage recommendations: 2 to 4 kg 4 ml 4 to 8 kg 8 ml 8 to 16 kg 16 ml 16 to 24 kg 24 ml 24 to 32 kg 32 ml 32 to 64 kg 64 ml For dogs weighing over 64 kg, an extra 10 ml are required for each additional 10 kg body weight. The dose should be added to feed, directly before feeding or administered by mouth directly after feeding. Treatment should be repeated when natural re-infection with parasitic worms occurs. Routine treatment of adult animals with minimal exposure to infection is advisable 2 to 4 times per year. More frequent treatment at 6 to 8 weekly intervals is advisable for dogs in kennels. Puppies and kittens under 6 months of age 0.5 ml per kg body weight daily for 3 consecutive days given by mouth directly after feeding to unweaned animals or added to feed for weaned animals, directly before feeding. (= 50 mg fenbendazole/kg body weight daily for 3 days) Practical dosage recommendations: Up to 1 kg 0.5 ml daily for 3 days 1 to 2 kg 1 ml daily for 3 days 2 to 4 kg 2 ml daily for 3 days 4 to 6 kg 3 ml daily for 3 days 6 to 8 kg 4 ml daily for 3 days 8 to 10 kg 5 ml daily for 3 days For puppies weighing over 10 kg, an extra 0.5 ml is required daily for each additional kg body weight. Puppies should be treated at 2 weeks of age, 5 weeks of age and again before leaving the breeder's premises. Treatment may also be required at 8 and 12 weeks of age. Thereafter, frequency of treatment can be reduced unless the pups remain in kennels where reinfection occurs more readily. Pregnant dogs 1 ml per 4 kg body weight daily from day 40 of pregnancy continuously to 2 days post-whelping (approximately 25 days) (= 25 mg fenbendazole/kg body weight daily) Practical dosage recommendations: 4 kg 1 ml daily for approx. 25 days 8 kg 2 ml daily for approx. 25 days 12 kg 3 ml daily for approx. 25 days 20 kg 5 ml daily for approx. 25 days 40 kg 10 ml daily for approx. 25 days For dogs weighing over 40 kg, an extra 1 ml is required daily for each additional 4 kg body weight.
