Cattle, sheep, horses and other equines.

Indications for use

A broad-spectrum anthelmintic for the treatment of cattle and sheep infected with mature and developing immature forms of nematodes of the gastro-intestinal and respiratory tracts.


For the treatment of cattle infected with:

Ostertagia spp.

Cooperia spp.
Trichostrongylus spp. Nematodirus spp.
Oesophagostomum spp. Haemonchus spp.
Bunostomum spp. Strongyloides spp.
Trichuris spp. Dictyocaulus viviparus
The product is usually effective against inhibited larvae of Ostertagia spp. and against Moniezia spp. of tapeworm.


For the treatment of sheep infected with benzimidazole susceptible:

Ostertagia spp. Haemonchus spp.
Trichostrongylus spp. Nematodirus spp.
Oesophagostomum spp. Cooperia spp.
Chabertia spp. Bunostomum spp.
Strongyloides spp. Dictyocaulus filaria
The product is usually effective against Moniezia spp. of tapeworm and may have useful but variable efficacy against Trichuris spp.


For the treatment and control of adult and immature roundworms of the gastro-intestinal tract in horses and other equines.

The product effectively treats and controls the following roundworm infections:

Large strongyles (adults and migrating larval stages of Strongylus vulgaris; adults and tissue larval stages of S. edentatus).

Benzimidazole-susceptible adult and immature small strongyles (Cyathostomes).

The product is also effective for the treatment and control of encysted mucosal 3rd and 4th stage small strongyle larvae and is also effective against encysted inhibited 3rd stage small strongyle larvae in the mucosa.

Adult and immature Oxyuris spp., Strongyloides spp. and Parascaris equorum.

Fenbendazole also has an ovicidal effect on nematode eggs.


Do not use in horses and other equines intended for human consumption.

Fenbendazole as a medicated liquid feed should not be used in the treatment of clinical infestations in cattle and sheep.

Special warnings for each target species

When administered by divided dosage in the form of liquid feed, the product may not be effective against Strongyloides and Trichuris spp. in cattle and Strongyloides, Dictyocaulus and Bunostomum spp. in sheep.

Care should be taken to avoid the following practices because they increase the risk of development of resistance and could ultimately result in ineffective therapy:

  • Too frequent and repeated use of anthelmintics from the same class, over an extended period of time.
  • Under dosing, which may be due to underestimation of body weight, misadministration of the product, or lack of calibration of the dosing device (if any).
  • Suspected clinical cases of resistance to anthelmintics should be further investigated using appropriate tests (e.g. Faecal Egg Count Reduction Test). Where the results of the test(s) strongly suggest resistance to a particular anthelmintic, an anthelmintic belonging to another pharmacological class and having a different mode of action should be used.

    Resistance to benzimidazoles (which include fenbendazole) has been reported in Teladorsagia, Haemonchus, Cooperia and Trichostrongylus species in small ruminants in a number of countries, including the EU. Therefore the use of this product should be based on local (regional, farm) epidemiological information about susceptibility of nematodes and recommendations on how to limit further selection for resistance to anthelmintics.

    Resistance to fenbendazole has been reported in cyathostomes in horses. Therefore the use of this product should be based on local (regional, farm) epidemiological information about susceptibility of nematodes and recommendations on how to limit further selection for resistance to anthelmintics.

    Special precautions for use

    When incorporating this product into liquid feed, after thoroughly shaking the suspension, measure the required volume of the suspension and add it to approximately 10 % of the liquid feed. Thoroughly mix this material and then add the remaining liquid feed and once again mix to produce a homogenous dispersion.

    Mix the medicated feed thoroughly prior to administration for example by rolling the drum or barrel.

    Assess body weight as accurately as possible before calculating the dosage.

    Intensive use or misuse of anthelmintic can give rise to resistance. To reduce this risk, dosing programmes should be discussed with your veterinary surgeon.

    Operator warnings

    Direct contact with the skin should be kept to a minimum. Wear suitable protective clothing including impermeable rubber gloves.

    Wash hands after use.

    Adverse reactions

However, for horses who fail to maintain condition or bought-in horses with unknown worming history, the treatment can be given at any time of the year.

    Pharmacological particulars

    Pharmacodynamic properties

    ATC Vet Code: QP52AC13

    Fenbendazole is an anthelmintic belonging to the benzimidazole carbamates group. It acts by interfering with 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.

    Pharmacokinetic properties

    Fenbendazole is only partly absorbed after oral administration and is then metabolised in the liver.

    The half life of fenbendazole in serum after oral application of the recommended dose in cattle is 10-18 hours and in sheep 21-33 hours. 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 sulfoxide then to sulfone and amines.
