To be given strictly by intramuscular injection, behind the ear. A long hypodermic
needle should be used and the injection given as closely behind the ear as possible
and perpendicular to the skin. There is a risk of injecting part of the drug into the fat,
if heavy animals are injected with a short needle into the neck. In this case, the
injection may have insignificant effect.
Do not re-inject if the animal is unresponsive to the initial dose, allow full recovery
before re-injecting on a different day.

An appropriately graduated syringe must be used to allow accurate administration of
the required dose volume. This is particularly important when injecting small volumes.
Do not administer more than 5 ml per injection site.
A dose of 1 mg/kg should not be exceeded in boars as a higher dose may cause the
penis to be extruded, which may then be damaged.
The rubber stopper can be punctured a maximum of 20 times. For multiple vial entry,
an aspirating needle or multi-dose syringe is recommended to avoid excessive
broaching of the stopper.
Do not use in very cold conditions as cardiovascular collapse and hypothermia
(increased by inhibition of hypothalamic heat regulation centre) due to peripheral
vasodilation may occur.
Do not use in case of transport and re-grouping of pigs if they will be slaughtered
prior to the end of
the withdrawal period.
Do not use in cases of hypersensitivity to the active substance or to any of the
excipients.
Pigs:
Undetermined frequency (cannot be
estimated from the available data):

competent authority via the national reporting system. See the package leaflet for

During onset of action treated animals should be left alone in a quiet environment.
Injection into adipose tissue may lead to apparent insufficient effect.
Occasional deaths have been observed in Vietnamese Pot Bellied pigs. It is thought
this may be caused by injection into the fat leading to slow induction and tendency to
use additional doses, leading to overdosage. It is important with this breed not to
exceed the stated dose.
Do not re-inject if the animal is unresponsive to the initial dose, allow full recovery
before re-injecting on a different day.
