Selgian Tablets for Dogs

Selgian is used to treat behavioural disorders in dogs which are associated with emotional upset, such as depression or anxiety. Ideally it is used alongside behaviour therapy when it is able to improve signs such as overactivity, phobias and anti-social behaviour. Selgian can also help dogs which have difficulty coping with periodic separation from their owners. Problems such as inappropriate urination or destructiveness when left alone can be improved. Selgian Tablets are given once daily for at least 2 months. The average treatment period is about 4 or 5 months, but can be longer. When required, it is acceptable to stop the medication suddenly, without a gradual withdrawal.



Cross-scored film-coated tablets, divisible into quarters by means of a groove to facilitate accurate dosage, for oral administration to dogs. Each tablet contains 4, 10 or 20 mg (-) selegiline hydrochloride.


Selegiline hydrochloride is an inhibitor of monoamine oxidase (IMAO type B) at the therapeutic dose in the dog; thus it modifies the concentration of monoaminergic neurotransmitters.

It is indicated for use as follows:

1.Treatment of behavioural disorders of purely emotional origin : depression, anxiety.

2.In association with behaviour therapy, treatment of signs of emotional origin observed in behavioural conditions such as overactivity, separation problems, generalised phobia and unsocial behaviour.

Emotional disorders are characterised by a modification of feeding, drinking, auto-stimulatory behaviour, sleep, exploratory behaviour, aggression related to fear and/or irritation, social behaviour and somatic disorders (tachycardia, emotional micturition).

Dosage and administration

For oral administration to dogs. The dose rate is 0.5 mg/kg/day (-) selegiline hydrochloride in a single administration.

For dogs weighing less than 8 kg, the use of Selgian® 4 mg is advisable. For dogs weighing more than 17 kg, the use of Selgian® 10 mg or Selgian® 20 mg is advisable. For dogs weighing less than 26 kg, the use of Selgian® 4 mg or 10 mg is advisable.

The treatment should be continued until the clinical condition is stable.

The minimum treatment period recommended is 2 months, based on the clinical trials results:

The treatment period was 2-3 months for 20% of the dogs.

The treatment period was 4-5 months for 50% of the dogs.

The treatment period was 6-7 months for 20% of the dogs.

The treatment period was >7 months for 10% of the dogs.

The treatment can be stopped suddenly without gradual dose reductions.

Contra-indications, warnings, etc

Owing to its IMAO properties, (-) selegiline hydrochloride may act on prolactin secretion. In the absence of specific studies, it is recommended that Selgian® should not be administered to pregnant and lactating bitches.

Selgian® should not be administered from the day before until the day after anaesthesia or tranquillisation performed with an alpha-2 agonist.

Do not administer with other alpha-2 agonists.

Selgian® should not be administered concomitantly with pethidine, fluoxetine or phenothiazines. The narcotic action of morphine is potentiated by Selgian®.

Emotional disorders can mask hierarchical conflicts. In dominant dogs suffering from an emotional disorder, the alleviation of the disorder can sometimes reveal a latent aggressiveness. In such cases, behavioural therapy must be instituted.

It is recommended to stop the treatment during pregnancy and lactation.

If no clinical improvement is observed after 2 months, continuing the treatment is unlikely to provide any further benefit. It is advisable to weigh animals before dosing to ensure the correct mg/kg dosage is administered.

The correct dose for your dog would be one and a quarter tablets daily. Ideally you should follow advice from a dog behaviour therapist at the same time, so as to get the maximum benefit from the tablets. He should become more receptive to being "trained" to improve, rather than hoping the tablets will do it all by themselves. (They might do, as long as you and the people he meets are able to respond appropriately to him. He needs to pick up the right signals from all of you to get the best benefit.)
