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 clinicalworm 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 lungwormOslerus (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.

5. PHARMACOLOGICAL PROPERTIES
Pharmacodynamic properties
Fenbendazole is an anthelmintic belonging to the benzimidazole carbamates group. It acts by interfering in the energy metabolism of the nematode. The anthelmintic efficacy is based on inhibition of the polymerisation of tubulin to microtubuli. The anthelmintic affects both adult and immature stages of gastro-intestinal and respiratory nematodes.
ATC Vet Code: QP52AC13
5.2 Pharmacokinetic particulars
Fenbendazole is only partly absorbed after oral administration and is then metabolised in the liver. Fenbendazole and its metabolites are distributed throughout the body and high concentrations can be found in the liver. The elimination of fenbendazole and its metabolites occurs primarily via the faeces (>90%) and to a small extent in the urine and milk.
Fenbendazole is metabolised to its sulphoxide, then to sulphone and amines.
