4. CLINICAL PARTICULARS


4.1 Target species


Cattle and Sheep


4.2 Indications for use, specifying the target species


A broad spectrum anthelmintic for the treatment and control of gastro-intestinal and pulmonary nematode infections in cattle and sheep, effective against mature and developing immature stages of the following levamisole-susceptible major nematode worm species:


Gastro-intestinal Worms:
Trichostrongylus spp.,Cooperia spp., Ostertagiaspp. (except inhibited Ostertagia larvae in cattle), Haemonchus spp., Nematodirus spp., Bunostomum spp., Oesophagostomum spp., Chabertia spp.


Lungworms: Dictyocaulus spp.

Not effective against Type II winter scour.


4.3 Contraindications


Animals should not be treated simultaneously or within 14 days before or after use with Organophosphorous compounds or diethylcarbamazine citrate.


4.4 Special warnings, for each target species


The product may be given to young, pregnant and lactating animals, but due regard must always be paid to the animals physical condition and the presence of inter-current disease. 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:


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. There are reports of resistance in Haemonchus in sheep in various parts of the world other than the EU. Resistance to levamisole has been reported in Teladorsagia species in cattle in 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.


4.5 Special precautions for use


i. Special precautions for use in animals


Care should be taken to accurately estimate the bodyweight of animals to be treated before calculating the dose.


For oral use only


ii. Special precautions to be taken by the person administering the veterinary medicinal product to animals


Levamisole can cause idiosyncratic reactions as well as serious blood disorders in a very small number of people. If symptoms such as dizziness, nausea or 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. Wash hands and exposed skin before meals and after work. Remove immediately any contaminated clothing. Wash splashes from eyes and skin immediately. If irritation persists, consult your doctor. When using do not eat, drink or smoke.


4.6 Adverse reactions (frequency and seriousness)


Occasionally at the recommended dose cattle may show signs of lip-licking and slight muscle tremor.


4.7 Use during pregnancy, lactation or lay


Can be safely used during pregnancy and lactation.


4.8 Interaction with other medicinal products and other forms of interaction


See 4.3 (2).


4.9 Amounts to be administered and administration route


The product should only be administered as an oral drench. The 500 ml Armadose presentation is for use only with the Armadose worming system. The 1L, 2.5L and 5L presentations are for use with conventional dosing gun systems. Dosing should be carried out accurately, at a dose rate of 7.5 mg Levamisole HCl per kg bodyweight.


To ensure administration of a correct dose, body weight should be determined as accurately as possible; accuracy of the dosing device should be checked.

Cattle over 300 kg should be given a further 1 ml for each additional 10 kg bodyweight


Sheep over 60 kg should be given a further 0.5 ml for each additional 5 kg bodyweight



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.


if the product does not achieve the desired clinical effect, since other diseases, nutritional disturbances or anthelmintic resistance may be involved.


Do not mix with other products.


4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary


At normal therapeutic dosages side effects are rarely seen. Overdose may occasionally result in the appearance of cholinergic-type symptoms such as salivation, muscular tremors and head shaking. They are more likely to be observed in cattle than in sheep.


4.11 Withdrawal period(s)


Animals must not be slaughtered for human consumption during treatment. Cattle and sheep may be slaughtered for human consumption only after 20 days from the last treatment.

Not for use in animals producing milk for human consumption


5. PHARMACOLOGICAL PROPERTIES


Levamisole Hydrochloride is a highly effective anthelmintic agent.

ATCvet code: QP52AE01


Pharmacodynamic properties


Levamisole Hydrochloride is a highly effective anthelmintic agent. Levamisole Hydrochloride is the laevoisomer of tetramisole hydrochloride. It is a broad spectrum anthelmintic with activity against a wide range of gastro-intestinal helminths and lungworms in cattle and sheep.

Levamisole is a ganglion stimulant of the nervous system of nematodes causing neuromuscular paralysis of the parasites. Because it acts on the nervous system it is not ovicidal.
