Amounts to be administered and administration route
Shake container before use.
Routine treatment of adult dogs and cats
4 ml per 1 kg bodyweight as a single oral dose.
(= 100 mg fenbendazole/kg bodyweight)
The dose should be added to feed, directly before feeding or administered by mouth directly after feeding.
Treatment should be repeated when natural re-infestation 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 and 8 weekly intervals is advisable for dogs in kennels.
Puppies and kittens under six months of age
2 ml per kg bodyweight 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 bodyweight daily for 3 days)
Practical dosage recommendations:
250 g 0.5 ml daily for 3 days
500 g 1 ml daily for 3 days
1 kg 2 ml daily for 3 days
1.5 kg 3 ml daily for 3 days
2 kg 4 ml daily for 3 days
For puppies weighing over 2 kg, an extra 2 ml is required daily for each additional kg bodyweight.
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 reinfestation occurs more readily.
Pregnant dogs
1 ml per 1 kg bodyweight daily from day 40 of pregnancy continuously to 2 days post-whelping (approximately 25 days)
(= 25 mg fenbendazole/kg bodyweight daily)
Practical dosage recommendations:
2 to 4 kg 4 ml daily for approx. 25 days
4 to 8 kg 8 ml daily for approx. 25 days
8 to 16 kg 16 ml daily for approx. 25 days
As treatment of pregnant dogs is 98% effective, puppies from these dogs should themselves be treated with a 3 day course at 2 and 5 weeks of age.
Pregnant cats
Pregnant cats can be safely treated but only require a single treatment at the routine adult dose rate. Administer 4ml per kg bodyweight as a single dose.
(=100mg fenbendazole/kg bodyweight)
Increased dosing for specific infections:
For the treatment of clinical worm infestations in adult dogs and cats or Giardia spp infections in dogs, administer 2 ml per kg bodyweight daily for 3 consecutive days.
(= 50 mg fenbendazole/kg bodyweight daily for 3 days)
For the control of lungworm Oslerus (Filaroides) osleri in dogs administer
2 ml per kg bodyweight, daily for 7 consecutive days.
(= 50 mg fenbendazole/kg bodyweight daily for 7 days)
A repeat course of treatment may be required in some cases.
For the control of lungworm Aelurostrongylus abstrusus in cats administer 2 ml per kg bodyweight daily for 3 consecutive days.
(=50 mg fenbendazole/kg bodyweight daily for 3 days)

Benzimidazoles have a high margin of safety.
