Known hypersensitivity to the active ingredient.
Special warnings
Selenium and cobalt are included as nutritional supplements and are not intended to be used therapeutically. Administration of ionophores to lambs has been shown to enhance selenium bioavailability. Concurrent administration of ionophores and Albex 2.5% SC may therefore lead to an increased risk of selenium toxicity. Cattle suffering from severe lung damage due to heavy lungworm infestation may continue to cough for some weeks after treatment.
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 a different pharmacological class and having a different mode of action should be used.
Resistance to benzimidazoles (which includes albendazole) has been reported in Teladorsagia Haemonchus, Cooper and Trichostrongylus species in small ruminants in a number of countries, including the EU. Resistance to albendazole has been reported in Cooperia and Teladorsagia species in cattle in developed countries such as New Zealand. 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 in animals
Care must be taken not to damage the pharyngeal region when dosing, particularly in sheep. Do not administer other cobalt and selenium supplements concurrently with this product unless specifically advised by your veterinary surgeon. Not to be diluted or mixed with other products. Avoid the introduction of contamination during use. Intensive use or misuse of anthelmintics can give rise to resistance. To reduce the risk, dosing programmes should be discussed with a veterinary surgeon.
The product should only be used in areas where deficiencies of selenium and cobalt are likely to occur. In cases of doubt, consult a veterinary surgeon.
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. Wear suitable clothing including impermeable rubber gloves. In the event of accidental eye exposure, flush eye thoroughly with running water. If irritation persists, seek medical attention. In the event of accidental skin exposure, wash the effected area with soap and water. If irritation persists, seek medical attention.
