Animals must not be treated within a period of 14 days before or after treatment with organophosphorus compounds or diethylcarbamazine citrate.
The product may be given to young, pregnant and lactating animals, but due regard must always be paid to the animal's physical condition and the presence of inter-current diseases.
When a dosing gun is used to administer the product, care should be taken to avoid the occurrence of dosing gun pharyngitis.
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 levamisole has been reported in Teladorsagia, Cooperia and Trichostrongylus
species in sheep in a number of countries, including the EU. There are reports of resistance in Haemonchus in sheep outside the EU. Resistance to levamisole has been reported in 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.
At normal therapeutic dosage side effects are rarely seen. Overdosage may occasionally result in the appearance of cholinergic-type symptoms such as salivation, muscular tremors and head shaking. These effects are more likely to be observed in cattle than in sheep.
Do not administer other cobalt and selenium supplements concurrently unless specifically advised by your veterinary surgeon. Not to be diluted.
Levacur SC 3% must not be used in animals producing milk for human consumption. Animals must not be slaughtered for human consumption during treatment. Sheep and cattle may be slaughtered for human consumption only after 20 days from last treatment.
When using, do not eat, drink or smoke. Wash splashes from eyes and skin immediately. Remove any contaminated clothing immediately. Wash hands and exposed skin before meals and after work. Levamisole can cause idiosyncratic reactions and serious blood disorders in a very small number of people.
If symptoms such as dizziness, nausea, vomiting or abdominal discomfort are experienced when using this product, or sore mouth/throat or fever occur shortly afterwards, then medical advice should be sought immediately.
For animal treatment only. Keep out of the sight and reach of children.
