4.4 Special warnings for each target species
Cattle with heavy lungworm infection may suffer an allergic response to the treatment as a result of killing worms in
situ.
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.
- Underdosing which may be due to underestimation of bodyweight, misadministration of the product, or lack of
calibration of the dosing device.
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 tests strongly suggest resistance to a particular anthelmintic, an anthelmintic belonging to another pharmacological class and having a different mode of action should be used.

4.5 Special precautions for use
Special precautions for use in animals
As with all oral drenches, care must be taken to avoid injury to the mouth and pharynx when using standard drenching equipment.

Special Precautions to be taken by the Person Administering the Medicinal Product to Animals

4.9 Amounts to be administered and administration route
The product is administered orally.
The recommended dosage rate is 7.5 ml of the product per 100 kg bodyweightequivalent to 7.5 mg Fenbendazole/kg bodyweight.
To ensure administration of a correct dose, bodyweight should be determined as accurately as possible.
If animals are to be treated collectively rather than individually, they should be grouped according to their bodyweight and dosed accordingly, in order to avoid under- or overdosing.
Use properly calibrated dosing equipment.
The veterinary surgeon should give advice regarding appropriate dosing programmes and stock management to achieve adequate parasite control.

4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary
Fenbendazole is extremely safe with a safety factor in excess of 100 times the recommended dose.

4.11 Withdrawal Period(s)
Animals intended for human consumption must not be slaughtered during treatment.
Cattle intended for human consumption may only be slaughtered from 21 days after the last treatment.
Not for use in animals producing milk for human consumption.

Pharmacotherapeutic group:
Anthelmintics, benzimadazoles and related substances

ATCvet code:
QP52AC13

5.2 Pharmacokinetic properties
Fenbendazole is slowly absorbed from the gut and peak blood levels are attained 28-30 h post treatment.
Amongst the many metabolites are the corresponding sulphone and sulphoxide, the latter is identical to Oxfendazole and may be mresponsible for its activity. Up to 35% of the dose is eliminated in the urine, most is excreted in the faeces.

Drench correctly
Sheep Oral Drench
The drenching technique is a vital part of ensuring that the wormer does its job effectively.
Make sure the sheep are properly restrained and cannot leap around when they are being drenched so they swallow the whole amount.
Sheep can also suffer serious injury, or even death, if they are unrestrained and the gun penetrates the tissues at the back of the mouth.
Place a hand under the head and tilt slightly to the side.
Slot the nozzle in the gap between molar and incisor teeth and then over the back of the tongue.
If the wormer is just put into the mouth, it will bypass the rumen as it escapes down the oesophageal groove and will be less effective.
This is particularly important for white (BZ) drenches.

Dosing Weight – do not guess. Underestimating the weight of sheep is a common cause of underdosing.
Select and weigh the biggest sheep in the group to determine the correct dose.
If there is a wide range of weights, consider splitting the group, then weigh the heaviest in each section.
Do not forget to check that the weigh crate is accurate before starting!

Calibrate and maintain the drench gun
Always check the gun is delivering the right amount before you drench. Remove the plunger from a 10 ml syringe, put a thumb over the end and squirt the dose into it, making sure there are no air bubbles left. Adjust the gun until the dose delivered is correct. Drenching guns should also be well maintained and replaced regularly. Clean with warm soapy water after use and check springs and tubes to make sure there are no kinks that will form air bubbles.

Withholding food
Research has shown that the efficacy of the white (BZ) and clear (AV) drenches can be improved by withholding food for 12–24 hours before treatment. It is not advised to deprive heavily pregnant ewes of food, so if you treat this class of stock with anthelmintics, you may wish to use yellow drenches (LV) because their efficacy is less dependent on rumen fill.

Storage
Wormers should be stored securely, away from direct sunlight at 4–25°C. Check the use-by date and, once open, use within the time shown on the packaging. Shake white (BZ) products well before use.

 Cattle Oral drenches
Oral drenching guns are designed to deliver the treatment towards the back of the mouth over the tongue, so the entire dose is swallowed at once to optimise efficacy.
• Make sure animals are properly restrained, with their head held up • Slide the nozzle of the dosing gun in the side of the mouth and over the tongue so that the entire dose is swallowed immediately
• Drenching equipment must be correctly calibrated and in good working order
• Calibrate the gun using the product just before treatment starts by delivering two or more doses into a graduated measuring cylinder Faulty equipment, or attempting to dose too quickly, may mean that the barrel of the gun does not fill properly or that the liquid is full of bubbles.
