4.4 Special Warnings for each target species


None.


4.5 Special precautions for use


For external use only.


i) Special precautions for use in animals


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 ivermectin (an avermectin) has been reported in Teladorsagia in sheep and goats within the EU and it is common in Haemonchus in sheep outside the EU. It has been reported in Cooperia oncophora in cattle within the EU, in Teladorsagia in cattle in developed countries such as New Zealand and Haemonchus in cattle outside the EU. 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 to be taken by the person administering the veterinary medicinal product to animals



Highly flammable - keep away from heat, sparks, open flame or other sources of ignition.


Paramectin Pour-On may be irritating to human skin and eyes and the user should be careful not to apply it to himself or other persons. Operators should wear nitrile rubber gloves and boots with a waterproof coat when applying the product. Protective clothing should be washed after use. If accidental skin contact occurs, wash the affected area immediately with soap and water. If accidental eye exposure occurs, flush the eyes immediately with water and get medical attention.


Do not smoke or eat while handling the product. Wash hands after use. Use only in well ventilated areas or outdoors.



Adverse reactions (frequency and seriousness)



Undesirable effects are not expected when the product is used at the recommended dose rate.



4.7 Use during pregnancy, lactation or lay

Paramectin Pour-On can be administered to beef cows at any stage of pregnancy or lactation provided that the milk is not intended for human consumption.




4.8 Interaction with other medicinal products and other forms of interaction

None.



Amounts to be administered and administration route



Ivermectin should be administered topically at 500 mg per kg bodyweight (1 ml per 10 kg bodyweight).


The formulation should be applied along the midline of the back in a narrow strip between the withers and the tailhead.


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


250 ml bottle and 1 litre pack

(Squeeze dispensing bottle/twin-neck container/single neck container)


2.5 litre and 5 litre pack

(Collapsible Back Pack)

Follow the applicator gun manufacturer’s directions for priming the gun, adjusting the dose, and care of the applicator gun following use.


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



No signs of toxicity are likely up to 5 mg/kg (10 times the recommended dose rate). There is no known antidote.



Withdrawal period



Cattle (meat): 28 days. Do not use in cows producing milk for human consumption. Do not use in non-lactating dairy cows including pregnant heifers within 60 days of calving.





5. pharmacological properties



Pharmacotherapeutic group: Anthelmintic


ATC Vet Code: QP54AA01



Pharmacodynamic properties


Ivermectin is a 22,23-dihydro derivative of an avermectin (which is a fermentation product produced by Streptomyces avermitilis) and consists of 2 homologues: B1a and B1b. It is a parasiticide with nematocidal, insecticidal and acaricidal activity documented in a wide range of domesticated animals.


Avermectins act to stimulate GABA mediated chloride ion conductance, causing irreversible neuromuscular blockade in nematodes, followed by paralysis and death.
