Clomicalm 20

This treatment applies to the following species:
Company: Elanco

Clomipramine hydrochloride

CLOMICALM is a twice daily oral treatment for dogs which has been shown to be effective when administered in combination with behavioural modification techniques for the treatment of anxieties and stereotypies (obsessive compulsive disorder).


Elanco Canada Limited encourages you to take time to read the package insert which describes the use of CLOMICALM (Clomipramine hydrochloride) to treat certain behavioural concerns in dogs. CLOMICALM is only available through veterinarians.


The active ingredient in CLOMICALM is clomipramine hydrochloride. The active ingredient in vivo is clomipramine and its major metabolite, desmethylclomipramine. Both clomipramine and desmethylclomipramine contribute to the broad-spectrum of action of CLOMICALM by blocking the neuronal re-uptake of both noradrenaline and serotonin (5-HT). CLOMICALM therefore possesses the properties of both a tricyclic antidepressant and a serotonin re-uptake inhibitor.

Clomicalm 20 Indications

Treatment of anxieties. Treatment of stereotypies (obsessive compulsive disorders) such as lick dermatitis.


CLOMICALM is administered twice daily at a dose of 1-2 mg/kg to give a total daily dose of 2-4 mg/kg according to the following table:

Body Weight

Dosage Per Administration




1.25 - 2.5 kg

> 2.5 - 5 kg

0.5 tablet

1 tablet



> 5 - 10 kg

> 10 - 20 kg


0.5 tablet

1 tablet


> 20 - 40 kg

> 40 - 80 kg



0.5 tablet

1 tablet


CLOMICALM is given orally with or without food. In clinical trials, CLOMICALM has been shown to be effective when administered for 2-3 months in combination with behavioural modification techniques for the treatment of anxieties (generalized anxiety and anxiety when separated from the owner). CLOMICALM has been shown to be also effective in the treatment of stereotypies (obsessive-compulsive disorder) such as lick dermatitis when administered for a minimum of 1 month.

Pharmacodynamic Properties

CLOMICALM contains clomipramine hydrochloride. The active ingredient in vivo is clomipramine and its major metabolite, desmethylclomipramine. Both clomipramine and desmethylclomipramine contribute to the effects of CLOMICALM: clomipramine is a potent and selective 5-HT re-uptake inhibitor while desmethylclomipramine is a potent and selective noradrenaline re-uptake inhibitor. The principle mechanism of action of CLOMICALM is potentiation of the effects of noradrenaline and 5-HT in the brain by inhibiting their neuronal re-uptake. In addition, CLOMICALM has anticholinergic effects by antagonism of cholinergic muscarinic receptors.

Pharmacokinetic Properties

Clomipramine is well absorbed (>80%) from the gastrointestinal tract in dogs when administered orally. When administered to fasted dogs, peak plasma levels of clomipramine and desmethylclomipramine are rapidly reached (1 - 1.5 hours). The pharmacokinetics of clomipramine and desmethylclomipramine are not significantly affected by co-administration of CLOMICALM with food.

Clomipramine is extensively bound to plasma proteins (>97%). Clomipramine and its metabolites are rapidly distributed in the body with high concentrations being achieved in organs and tissues (including the lungs, heart and brain) and low concentrations remaining in the blood.

The major route of bio-transformation of clomipramine is demethylation to desmethylclomipramine. Additional polar metabolites also exist.

The elimination t 1/2 of clomipramine is 6.4 hours and that of desmethylclomipramine is 3.8 hours. The principle route of excretion is via the bile (>80%) with the remainder via the kidneys.

Side Effects

CLOMICALM may cause mild and intermittent vomiting in some dogs, this may be improved by co-administration with a small quantity of food.


Oral administration of clomipramine at 40 mg/kg caused no significant signs of toxicity in dogs. Administration of toxicological doses of clomipramine (735 mg/kg) to dogs caused non-specific signs of CNS inhibition and convulsions. There is no specific antidote. In the event of overdose, treatment should be supportive.


This product is well tolerated by the target species.

Use During Pregnancy And Lactation

The safety of CLOMICALM has not been established in male and female reproductive dogs. CLOMICALM is recommended for use in breeding dogs only if the benefit/risk ratio is considered justified by the veterinarian.

Interaction With Other Medicaments

The need for specific precautions has not been established in dogs. In clinical trials, there were no adverse effects when CLOMICALM was used with a variety of antibiotics, vaccines, anti-parasitic drugs, and CNS active drugs. CLOMICALM may potentiate the effects of CNS depressant drugs such as barbiturates. It is recommended not to administer CLOMICALM in combination with, or within 2 weeks of cessation of therapy with, monoamine oxidase inhibitors.


Tolerability studies and clinical trials have demonstrated no need for special precautions with the use of CLOMICALM in dogs. From its known mechanism of action, it is recommended to use CLOMICALM with care in dogs with cardiac arrhythmias, epilepsy or narrow angle glaucoma.


Keep out of reach of children. If accidentally swallowed, call a physician.
