4. CLINICAL PARTICULARS
4.1 Target species
Sheep
4.2 Indications for use, specifying the target species
Broad spectrum worm and fluke drench;
For the control of adult and larval stages of benzimidazole-sensitive gastro-intestinal roundworms (Bunostomum, Chabertia, Cooperia, Haemonchus, Nematodirus, Oesophagostomum, Ostertagia, Strongyloides andTrichostrongylus), tapeworms (Moniezia) and lungworms (Dictyocaulusfilaria), and for the control of adult liver fluke (Fasciola hepatica) and the treatment of chronic, but not acute, fascioliasis in sheep.
Ovicidal to round worm eggs.
Also aids in the prevention of cobalt and selenium deficiency.
Contraindications
Ewes should not be treated at the fluke and worm dose during tupping and until one month after the tups are removed.
Not recommended for use in cattle.
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.
-
Underdosing, 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 has been reported in Teladorsagia, Haemonchus, Cooperia, and Trichostrongylusspecies in small ruminants. 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.
4.5 Special precautions for use
i. Special precautions for use in animals
Shake container well before use.
For oral administration only.
The product should only be used in areas known to be deficient in cobalt and selenium. Do not administer other cobalt and selenium supplements concurrently unless specifically advised by your vet. If in doubt, consult a veterinary surgeon.
Not to be diluted.
ii. Special precautions to be taken by the person administering the veterinary medicinal product to animals
Wash hands after use.
Avoid direct contact with the product.
In the case of accidental eye exposure, flush copiously with water for at least 15 minutes, holding the eye open, and seek medical attention.
In the event of accidental skin exposure, wash the affected area with soap and water. If irritation persists, seek medical attention.
Adverse reactions (frequency and seriousness)
Frequent use or misuse of anthelmintics may enhance the development of resistance. If unsure of the resistance status of worms on your property, consult your veterinary surgeon for advice on conducting a resistance test.
Use during pregnancy, lactation or lay
At the worm dose, Rycoben SC for Sheep is suitable for the treatment of sheep of all ages; however, care should be taken not to exceed the recommended dose, especially during the first month of pregnancy.
Ewes should not be treated at the fluke and worm dose during tupping and until one month after the tups are removed.
Ensure careful handling of ewes if used near lambing time.
4.8 Interaction with other medicinal products and other forms of interaction
None known
4.9 Amounts to be administered and administration route
Do not mix with other products.
Administer orally using standard drenching equipment.
To ensure administration of a correct dose, body weight should be determined as accurately as possible; accuracy of the dosing device should be checked.
Use the dose volume appropriate to the heaviest animals when treating on a group basis.
Worm Dose:
Dosage: 5mg albendazole oxide* per kg bodyweight (1ml per 5kg bodyweight). The dosage rates of trace elements are 0.75mg cobalt per kg and 0.08mg selenium per kg bodyweight.

Dosing Programme:
Ewes and gimmers
Dose ewes 2-6 weeks before lambing and again soon after lambing. On heavily stocked pastures, treatment at intervals of 3-4 weeks may be necessary until autumn. Otherwise treat prior to tupping and at housing.
Lambs and hoggs
Lambs at risk from Nematodirus infection require dosing at 2 week intervals. Otherwise treat lambs from 4-6 weeks of age and hoggs from late May at 3 week intervals until autumn. Dose at weaning and move to clean pasture. If clean pasture is unavailable, dose at 3-4 week intervals until sold, or until early winter.
Treat all bought-in sheep before allowing to mix with the flock. (N.B. Most independent advice recommends the use of an avermectin (3-AV) containing product at this time).
Fluke and Worm Dose:
Dosage: 7.5mg albendazole oxide* per kg bodyweight (1.5ml per 5kg bodyweight). The dosage rates of trace elements are 1.125mg cobalt per kg and 0.12mg selenium per kg bodyweight.

Dosing Programme:
Dose all ewes 2-6 weeks before and soon after lambing to reduce pasture contamination with roundworm eggs and control chronic fluke disease.
Dose all sheep in October/November and repeat at 4-6 week intervals until spring for outwintered stock.
4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary
The therapeutic margin for this product is high and problems due to overdosage are therefore unlikely.
Withdrawal period(s)
Meat: Animals must not be slaughtered for human consumption during treatment. Sheep may be slaughtered for human consumption only after 3 days from the last treatment.
Milk: Not for use in sheep producing milk for human consumption.
5. PHARMACOLOGICAL PROPERTIES
Pharmacotherapeutic group: Anthelmintic
ATC vet code: QP52AC11
Pharmacodynamic properties
Albendazole oxide (ricobendazole) is an anthelmintic belonging to the benzimidazole group. Its mode of action, in common with other benzimidazoles is the disruption of microtubule formation by extensive binding to nematode tubulin. It is active against larval and adult stages, andis ovicidal.
5.2 Pharmacokinetic particulars
Albendazole oxide is slowly metabolised to a range of metabolites by hydroxylation, oxidation to sulphones, deacetylation to form amines and reduction to negligible amounts of albendazole. The most important metabolites are the sulphone and the 2-amino sulphone, neither of which is anthelmintically active.
