Routine treatment of adult dogs and cats

Administer 100mg fenbendazole per 1kg (2.2lb) bodyweight as a single dose.

 

Practical dosage recommendations:

1 g sachet /dose Treats 2kg (4.4lb) bodyweight as a single dose (1.1 – 2.2kg)

1.8 g sachet / dose Treats 4kg (8.8lb) bodyweight as a single dose (2.2 – 4.4kg)

For dogs weighing over 10kg (22lb), additional sachets are required according to the additional bodyweight.

 

Assess bodyweight as accurately as possible and then administer one or a combination of the above sachets, which most closely doses this bodyweight. The dose should be administered by mixing into the feed.

 

e.g.For a 9kg dog = 2kg dose (1g sachet) + 4kg dose (1.8g sachet) + 4kg dose (1.8g sachet).

 

i.e. one x 1gram sachet + two x 1.8gm sachets. (10kg dose)

or, one x 4.5gram sachet (10kg dose)

 

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.

 

Weaned puppies and kittens under six months of age

 

Administer 50mg fenbendazole per 1kg (2.2lb) bodyweight daily for 3 consecutive days.

5.     PHARMACOLOGICAL PROPERTIES

 

5.1   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: QP52 AC 13

5.2   Pharmacokinetic particulars

Fenbendazole is only partly absorbed from the intestine and reaches maximum plasma concentration in dogs 6 - 24 hours after oral administration. In cats the mean maximum serum concentration of fenbendazole was reached about 4 hours after treatment. Administration of fenbendazole in food did significantly increase its bioavailability compared to the administration on an empty stomach.

Fenbendazole is metabolised mainly by enzymes of the cytochrome P -450 system in the liver. The major oxidative metabolite is fenbendazole sulfoxide which is further metabolised to fenbendazole sulfone.

Fenbendazole and its metabolites are distributed throughout the body but highest concentrations are found in the liver.

The elimination half-life from plasma is about 15 hours after oral administration.

Fenbendazole and its metabolites are predominantly excreted via the faeces.
