Contra-indications, warnings, etc
At normal therapeutic dosages side effects are rarely seen. Overdosage 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.
Care should be taken to estimate accurately the bodyweight of animals to be treated before calculating the dosage. Cattle 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.
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, since other diseases, nutritional disturbances or anthelmintic resistance may be involved. When a dosing gun is used to administer the product, care should be taken to avoid occurrences of dosing gun pharyngitis.
