4.1 Target species

Pigs, goats, sheep, cattle, horses, cats and dogs

4.2 Indications for use, specifying the target species:

For Euthanasia.

4.3 Contraindications

Do not use for anaesthesia.

Carcasses and edible products of animals injected with this product may never enter the food chain and other animals may never eat (parts of) the carcass (see section 4.11)

4.4 Special warnings for each target species

Intravenous injection of pentobarbital has the ability to cause induction excitement in several species of animal and adequate sedation should be applied if deemed necessary by the veterinary surgeon. Measures must be taken to avoid perivascular administration (e.g. by using intravenous catheter).

Check regularly, up to about 10 minutes post-administration, if live signs return (respiration, heartbeat, corneal reflex). In clinical trials it has been established that this might occur. If such live signs return, it is advised to repeat the administration using between 0.5 and 1 times the prescribed dose.

Avoid use in animals weighing less than 20kg due to the highly concentrated nature of the product and increased risk of pain and irritation if administered perivascularly.

To reduce the risk of induction excitement, euthanasia should be performed in a quiet area.

Particularly in horses and cattle,the veterinary surgeon should consider premedication with an appropriate sedative to produce profound sedation before euthanasia and an alternative method of euthanasia is recommended to be available should it become necessary.

4.5 Special precautions for use

Special precautions for use in animals


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

Pentobarbital is a potent hypnotic and a sedative, and thus potentially toxic in man. It can be adsorbed systemically through the skin and if swallowed. Particular care should be taken to avoid accidental ingestion and self-injection

Systemic uptake (including absorption via skin or eye) of pentobarbital causes sedation, sleep induction and respiratory depression. Moreover, this product may be irritating to the eye and can cause irritation to the skin as well as hypersensitivity reactions (due to the presence of pentobarbital and benzyl alcohol). Embryotoxic effects cannot be excluded.

Avoid direct contact with the skin and eyes, including hand-to-eye contact.

Avoid accidental self-injection or accidental injection of a second professional when administering the product.

People with known hypersensitivity to pentobarbital should avoid contact with the veterinary medicinal product

Handle the product with utmost care, especially women of childbearing potential. Wear protective gloves. This medicine should only be administered by veterinarians and should only be used in the presence of another professional that can assist in case of accidental exposure. Instruct the professional if not a medical professional about the risks of the product.

Accidental spillage on the skin or in the eye must be washed off immediately with plenty of water; If there has been serious skin or eye contact or in case of accidental self-injection, seek medical advice immediately and show the package leaflet or the label to the physician. In case ofaccidental ingestion, wash out mouth and obtain medical attention immediately. But DO NOT DRIVE as sedation may occur.

After administration of this product, collapse will occur within 10 seconds. In case the animal is standing at time of administration, care should be taken by the person administering the veterinary medicinal product and any other persons present to keep a certain distance from the animal to avoid injury

This product is flammable, keep away from sources of ignition. Do not smoke.

Information for the health professional in case of exposure:

Emergency measures should be directed toward maintenance of respiration and cardiac function. In severe intoxication measures to enhance elimination of absorbed barbiturate may be necessary.

The concentration of pentobarbital in the product is such that the accidental injection or ingestion of quantities as small as 1ml in human adults can have serious CNS effects. A dose of pentobarbital sodium of 1g (equivalent to 2.5ml of product) has been reported to be fatal in humans. Treatment should be supportive with appropriate intensive therapy and maintenance of respiration.

4.6 Adverse reactions (frequency and seriousness)

Death may be delayed if the injection is administered perivascularly or into organs/tissues with low capacity for absorption. Barbiturates can be irritating when administered perivascularly.



Very rare:

4.7 Use during pregnancy, lactation or lay

No specific information is available. The use of this product in pregnant animals is left to the judgement of the veterinarian.

4.8 Interaction with other medicinal products and other forms of interaction

CNS depressants (narcotics, phenothiazines, antihistamines, etc.) may increase the effect of pentobarbital.

4.9 Amounts to be administered and administration route

Cattle, horses, pigs, goats, sheep, cats and dogs:

100 mg/kg (corresponding to 0.25 ml/kg) through quick intravenous injection. For larger animals, the use of a pre-inserted intravenous catheteris advocated

If cardiac arrest is not established after 2 minutes, a second dose needs to be administered, preferably via fast intravenous injection or if this is not feasible, via intra-cardiac injection; intra-cardiac injection is only acceptable after prior deep sedation or anaesthesia.

As the vial cannot be punctured more than 20 times, the user should choose the most appropriate vial size.

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

In the event of accidental administration to an animal not presented for euthanasia, measures such as artificial respiration, administration of oxygen and the use of analeptics are appropriate.

In view of the activity of this product, double dosage is discouraged, as this will not result in a faster or better euthanasia.

4.11 Withdrawal period

Not applicable

Appropriate measures need to be taken to assure that carcasses and edible products of animals injected with this product do not enter the food chain, and are not used for human consumption. Other animals may never eat (parts of) the carcass, as they might be exposed to a lethal dose of pentobarbital.


Pharmacotherapeutic group:Barbiturates intended for euthanasia.

ATCvet code:QN51AA01.

5.1 Pharmacodynamic properties

Pentobarbital is a short-acting sedative and hypnotic. It causes depression of the central nervous system by GABA receptor modulation, imitating the action of Gamma-aminobutyric acid.

Barbiturates suppress in particular the reticular activating system (RAS) in the brain, which normally ensures alertness. The immediate effect is the loss of consciousness followed by deep anaesthesia followed by, at high rates, rapid depression of the respiratory centre. Breathing stops and is quickly followed by cardiac arrest and rapid death.

5.2 Pharmacokinetic particulars

After intravenous administration fast distribution over the tissues will occur.

Pentobarbital is mainly eliminated through the liver by biotransformation, particularly by the Cytochrome P450system, as well as by excretion in the kidneys and redistribution. In pigs redistribution in fatty tissue might cause reduced plasma concentrations and prolonged action.

Barbiturates may diffuse through the placenta in foetal tissue, and traces of barbiturates may be present in the breast milk.
