Indications

Treatment of chickens infected with Heterakis gallinarum (adult stages), Ascaridia galli (adult stages), Capillaria obsignata (adult stages) or Raillietina echinobothrida (adult stages).

Treatment of pheasants infected with Heterakis gallinarum (adult stages).

Dose to be administered and administration route

In drinking water use.

Shake well before use.


Underdosing could result in ineffective use and may favour resistance development.


To ensure a correct dosage, body weight should be determined as accurately as possible. If animals are to be treated collectively, reasonably homogeneous groups should be set up, and all animals of a group should be dosed at the rate corresponding to the heaviest one.

Accuracy of the dosing device should be thoroughly checked.

Before allowing animals to have access to the medicated water, the water delivery system should be drained, if possible, and flushed with the medicated water to ensure accuracy of dosing. This procedure may need to be performed on all treatment days.

The intake of medicated water depends on the clinical condition of the animals. In order to obtain the correct dosage, the concentration of fenbendazole may need to be adjusted accordingly.

Ascaridia galli and Heterakis gallinarum: The dose is 1.0 mg fenbendazole per kg body weight per day (equivalent to 0.005 ml of the veterinary medicinal product).

This dose has to be administered on 5 consecutive days.

Capillaria obsignata: The dose is 2.0 mg fenbendazole per kg body weight per day (equivalent to 0.01 ml of the veterinary medicinal product). This dose has to be administered on 5 consecutive days.

Raillietina echinobothrida: The dose is 3.0 mg fenbendazole per kg body weight per day (equivalent to 0.015 ml of the veterinary medicinal product). This dose has to be administered on 10 consecutive days.


Dose calculation:

The required daily amount of veterinary medicinal product is calculated from the total estimated body weight (kg) of the entire group of chickens or pheasants to be treated. Please use the following formula:


Treatment of Ascaridia galli and Heterakis gallinarum:

ml veterinary medicinal product/day = total estimated body weight (kg) of chickens/pheasants to be treated x 0.005 ml


Treatment of Capillaria obsignata:

ml veterinary medicinal product/day = total estimated body weight (kg) of chickens to be treated x 0.01 ml


Treatment of Raillietina echinobothrida:

ml veterinary medicinal product/day = total estimated body weight (kg) of chickens to be treated x 0.015 ml


Follow the instructions described below to prepare the medicated water. Use a sufficiently accurate commercially available measuring device.

For each treatment day the medicated water needs to be freshly prepared.

For use in medication tank:

For use in chickens, add the calculated amount of veterinary medicinal product to 40-80% of the daily water ration. For use in pheasants, add the calculated amount of veterinary medicinal product to 40% of the daily water ration. Stir until content in the medication tank is visibly homogeneous. The medicated water appears hazy. No further stirring during administration is necessary.

For use in dosing pump:

Add the calculated amount of veterinary medicinal product to the unmedicated water in the stock suspension container of the dosing pump. The volume of unmedicated water in the stock suspension container has to be calculated taking as a basis the preset injection rate of the dosing pump and 40 to 80% of the chickens’ daily water ration or 40% of the pheasants’ daily water ration. Stir until content in the stock suspension container is visibly homogeneous. The medicated water appears hazy.

During treatment all animals must have unrestricted access to the medicated water as the sole source of drinking water.

During treatment, after complete consumption of the medicated water, animals must be allowed access to un-medicated drinking water as soon as possible.

Ensure that the total amount of medicated water offered is consumed.

4.3 Contraindications

Do not use in cases of hypersensitivity to the active substance or to any of the excipients.

4.4 Special warnings for each target species

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.

The uptake of medicated water depends on age and clinical conditions of the birds, ambient temperature and light regime. In order to obtain the correct dosage concentration of the product should be adjusted accordingly.

Ascaridia galli and Heterakis gallinarum: The dose is 1.0 mg fenbendazole per kg body weight per day (equivalent to 0.005 ml of the product). This dose has to be administered on 5 consecutive days.

Capillaria obsignata: The dose is 2.0 mg fenbendazole per kg body weight per day (equivalent to 0.01 ml of the product). This dose has to be administered on 5 consecutive days.

Dose calculation:

The required daily amount of product is calculated from the total estimated body weight (kg) of the entire group of chickens or pheasants to be treated. Please use the following formula:

Treatment of Ascaridia galli and Heterakis gallinarum:

ml product/day = total estimated body weight (kg) of chickens/pheasants to be treated x 0.005 ml Treatment of Capillaria obsignata:

ml product/day = total estimated body weight (kg) of chickens to be treated x 0.01 ml

Follow the instructions described below to prepare the medicated water. Use a sufficiently accurate commercially available measuring device.

For each treatment day the medicated water needs to be freshly prepared.

For use in medication tank:

For use in chickens, add the calculated amount of product to 40-80% of the daily water ration. For use in pheasants, add the calculated amount of product to 40% of the daily water ration. Stir until content in the medication tank is visibly homogeneous. The medicated water appears hazy. No further stirring during administration is necessary.

For use in dosing pump:

Add the calculated amount of product to the unmedicated water in the stock suspension container of the dosing pump. The volume of unmedicated water in the stock suspension container has to be calculated taking as a basis the preset injection rate of the dosing pump and 40 to 80% of the chickens’ daily water ration or 40% of the pheasants’ daily water ration. Stir until content in the stock suspension container is visibly homogeneous. The medicated water appears hazy.

During treatment all animals must have unrestricted access to the medicated water as the sole source of drinking water.

5. PHARMACOLOGICAL PROPERTIES

Pharmacotherapeutic group: Anthelmintics, benzimidazole derivatives - fenbendazole.

ATCvet Code: QP52AC13

5.1 Pharmacodynamic properties

Fenbendazole is an anthelmintic belonging to the benzimidazole-carbamate group. It acts by interfering with the energy metabolism of the nematode.

Fenbendazole inhibits the polymerisation of tubulin to microtubules. This interferes with essential structural and functional properties of the cells of helminths, such as formation of the cytoskeleton, formation of the mitotic spindle and the uptake and intracellular transport of nutrients and metabolic products. Fenbendazole is active and

has a dose dependent activity on Heterakis gallinarum (adult stages), Ascaridia galli (adult stages) and Capillaria obsignata (adult stages) in chickens, and activity against adult Heterakis gallinarum in pheasants.

5.2 Pharmacokinetic particulars

After oral administration fenbendazole is only partially absorbed. Following absorption, fenbendazole is rapidly metabolised in the liver mainly to its sulphoxide (oxfendazole) and further to its sulphone (oxfendazole sulphone). In chickens oxfendazole sulfone is the main component detected in plasma, accounting for about 3/4 of the total AUC (i.e. the sum of the AUC for fenbendazole, oxfendazole and oxfendazole sulphone). Fenbendazole and its metabolites are distributed throughout the body, reaching highest concentrations in the liver.

The elimination of fenbendazole and its metabolites occurs primarily via the faeces.
