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
Ivermectin should be administered at a dosage rate of 200 g per kg
bodyweight (1 ml to 50 kg bodyweight). It should only be injected
subcutaneously in front of or behind the shoulder using aseptic
technique. A sterile 17 gauge x ½ inch needle is recommended.

Revised: December 2009
AN: 01262/2009
Sheep
Administer only by subcutaneous injection in the neck at the
recommended dosage level of 200 g ivermectin per kg bodyweight
using aseptic technique. Each ml contains 10 mg ivermectin to treat 50
kg of bodyweight. Swab the septum before removing each dose. Use
a dry sterile needle and syringe.
Administer subcutaneously only. Inject once under the loose skin in
the neck. For the treatment and control of sheep scab (Psoroptes ovis)
two injections with a seven day interval are required to treat clinical
signs of scab and eliminate living mites. Use of a 17 gauge x ½ inch
(15-20 mm) needle is suggested. Replace with a fresh sterile needle
after every 10-12 animals. Injection of wet or dirty animals is not
recommended.
When treating sheep of less than 16 kg seek veterinary advice
regarding the use of 1 ml disposable syringes graduated in increments
of 0.1 ml.
For the treatment of individual sheep a syringe not exceeding 2.0 ml
and calibrated in increments of 0.1 ml should be used.
Pigs
Administer at a dosage rate of 300 µg per kg bodyweight (1 ml per 33
kg). The product should be injected subcutaneously into the neck
using aseptic technique. A sterile 17 gauge x ½ inch needle is
recommended.
This product does not contain an antimicrobial preservative. Swab
septum before removing each dose. Use a dry sterile needle and
syringe. For 250 ml, 500 ml and 1 litre pack sizes, use of a multiple
dose syringe is recommended. To refill the syringe, use of a draw-off
needle is recommended to avoid excessive broaching of the stopper.
Avoid introduction of contamination.
The product is for administration only by the subcutaneous route and
must not be given via other routes. It should not be used in other
species than those indicated as severe reactions, including fatalities in
dogs, may occur.
Transitory discomfort has been observed in some cattle following
subcutaneous administration. Tissue swellings at the injection site
have been observed. These reactions resolve without treatment.
See also 4.10.
Immediately following subcutaneous injection, activity suggesting pain,
sometimes intense but usually transient, has been observed in some
sheep.

Care should be taken to avoid the following practices because they
increase the risk of development of resistance and could ultimately
result ineffective therapy:
•
class, over an extended period of time.
•
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 ivermectin (an avermectin) has been reported in
Telodorsagia 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 in cattle in
developed countries such as New Zealand and outside
the EU. Therefore the use of this product should be based on local
(regional, farm) epidemiological information about the susceptibility of

Revised: December 2009

nematodes and recommendations on how to limit further selection for
resistance to anthelmintics.
(i) Special precautions for use in animals
In pigs, especially those under 16 kg for which less than a volume of
