Contra-indications, warnings, etc
Do not administer to non-ruminating calves or calves less than 12 weeks of age.
Do not administer to animals weighing less than 100 kg or exceeding 400 kg.
Do not exceed stated dose.
Do not use the bolus concurrently with other bolus products, excepting Cosecure† and Rumbul†† Magnesium Bullets.
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 (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 result 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 some parasite species in cattle. Therefore the use of the 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. Only gentle pressure should be used during bolus administration.
If lungworm vaccination is practised in calves before turnout, the bolus should not be administered until after the second dose of vaccine has been given, thus ensuring that a period of at least three weeks elapses between lungworm vaccination and the release of the first dose of oxfendazole from the bolus.
No other anthelmintic should be given to a treated animal whilst the bolus is still active except:
1Where clinical signs of a lungworm infestation become evident.
2Where dosing for liver fluke becomes necessary.
If a treated animal is sold, then the purchaser must be informed of the date on which the bolus was administered.
As with other anthelmintics, veterinary advice should be sought on appropriate dosing programmes and stock management to achieve adequate parasite control, and to reduce the likelihood of anthelmintic resistance developing and also if the product does not achieve the desired clinical effect, as other diseases, nutritional disturbances or anthelmintic resistance might be involved.
Wash hands after use.
Withdrawal periods
Cattle (meat): 8 months.
Milk: not for use in cattle producing milk for human consumption, nor for cattle within eight months of an expected calving date which precedes the production of milk for human consumption.
