Clinical information

- Premedication prior to general anaesthesia.
To ensure a correct dosage, body weight should be determined as accurately as
possible.
AN: 04155/2025 & 04156/2024
Dogs:
For sedation:
The veterinary medicinal product should be administered at a dose of 10-80 µg of
medetomidine hydrochloride per kg of body weight (corresponding to 0.1 – 0.8 ml/ 10
kg body weight).
Maximal effect is obtained within 15-20 minutes. Clinical effect is dose-dependent,
lasting 30 to 180 minutes.
For premedication:
The veterinary medicinal product should be administered at a dose of 10-40 µg
medetomidine hydrochloride per kg body weight (corresponding to 0.1-0.4 ml/ 10 kg
body weight). The exact dose depends on the combination of drugs used and the
dosage(s) of the other drug(s).
The dose should furthermore be adjusted to the type of surgery, length of procedure
and patient temperament and weight. Premedication with medetomidine will
significantly reduce the dosage of the induction agent required and will reduce
volatile anaesthetic requirements for maintenance anaesthesia. All anaesthetic
agents used for induction or maintenance of anaesthesia should be administered to
effect. Before using any combinations, product literature for the other products should
be observed. See also section 3.5.
Cats:
For sedation:
The veterinary medicinal product should be administered at a dose of 50 – 150 µg
medetomidine hydrochloride per kg body weight (corresponding to 0.05 – 0.15 ml/ kg
body weight).
For premedication for anaesthesia:
The veterinary medicinal product should be administered at a dose of 80 µg
medetomidine hydrochloride per kg body weight (corresponding to 0.08 ml/ kg body
weight).
Use the table below to determine the correct dosage on the basis of body weight.

The speed of induction is slower when subcutaneous route of administration is used.
The stopper may be safely punctured up to 50 times.
Do not use in animals with serious cardiovascular disease, respiratory disease or
hepatic or renal disorders.
Do not use in cases of obstructive disorders of the gastrointestinal tract (such as
torsion of the stomach, blockage, obstruction of the oesophagus).
Do not use in cases of hypersensitivity to the active substance or to any of the
excipients.
AN: 04155/2025 & 04156/2024
Do not use in animals with diabetes mellitus.
Do not use in animals in a state of shock, emaciation or serious debilitation.
Do not use in animals with ocular problems where an increase in intraocular pressure
would be detrimental.
Do not use concomitantly with sympathomimetics or sulphonamides and
trimethoprim.

AN: 04155/2025 & 04156/2024
Some dogs and most cats will vomit within 5-10 minutes of injection. Cats may also
vomit on recovery.
Recurrence of sedation after initial recovery has been reported.
Reversible hyperglycaemia due to depression of insulin secretion.
Dogs with a body weight of less than 10 kg may show the undesirable effects
mentioned above more often.
Reporting adverse events is important. It allows continuous safety monitoring of a
veterinary medicinal product. Reports should be sent, preferably via a veterinarian, to
either the marketing authorisation holder or its local representative or the national
competent authority via the national reporting system. See the package leaflet for
respective contact details.
Medetomidine may not provide analgesia throughout the entire sedation period;
therefore, the use of additional analgesics should be considered during painful
surgical procedures.

Special precautions for safe use in the target species:
A clinical examination should be carried out in all animals before the use of veterinary
medicinal products for sedation and/or general anaesthesia.
When the veterinary medicinal product is used for premedication, the dose of the
anaesthetic should be reduced accordingly and titrated to response, due to the
considerable variability in requirements between patients. Before using any
combinations, the warnings and contraindications in the product literature for the
other product(s) should be observed.
Medetomidine can produce respiratory depression; in such cases, manual ventilation
and administration of oxygen may be required.
Higher doses of medetomidine should be avoided in large breed dogs. Care should
be taken when combining medetomidine with other anaesthetics or sedatives
because of its marked anaesthetic sparing effects. Animals should be fasted 12
hours before anaesthesia.
The animal should be placed in a calm and quiet environment to reach a maximum
sedative effect. This takes about 10-15 minutes. Do not start any procedure or
administer other medicines before maximum sedation is reached.
Treated animals should be kept warm and at a constant temperature, both during the
procedure and during recovery. Vomiting and perianesthetic reflux may occasionally
lead to regurgitation of gastric contents to the mouth.
Due to decreased tear flow, the eyes should be protected by a suitable lubricant
(appropriate ophthalmic ointment or artificial tear solution).
Animals should be allowed to calm down before initiation of treatment.
Sick and debilitated dogs and cats should only be premedicated with medetomidine
before induction and maintenance of general anaesthesia based on a risk-benefit
assessment.
Care should be taken with use of medetomidine in animals with cardiovascular
disease, or which are old or in general poor health. Liver and kidney function should
be evaluated prior to use.
In order to reduce the recovery time after anaesthesia or sedation, the effect of the
veterinary medicinal product can be reversed by the administration of an alpha-2-
antagonist such as atipamezole.
Atipamezole does not reverse the effect of ketamine. As ketamine alone can elicit
convulsions in dogs and cramps in cats, alpha-2 antagonists should not be given less
AN: 04155/2025 & 04156/2024
than 30-40 min. after the administration of ketamine. It should be considered that
bradycardia might persist after reversal.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals:
This veterinary medicinal product is a sedative. Care should be taken to avoid skin,
eye, mucosal
contact and self-injection.
In the case of accidental contact of the veterinary medicinal product with the skin or
eyes, rinse with large amounts of fresh water. Remove contaminated clothes that are
in direct contact with skin. If symptoms occur, seek medical advice.
In case of accidental ingestion or self-injection, seek medical advice immediately and
show the package leaflet or the label to the physician. DO NOT DRIVE as sedation
and changes in blood pressure may occur.
Pregnant women should handle the veterinary medicinal product with special care to
avoid self-injection. Uterine contractions and decreased foetal blood pressure may
occur after accidental systemic exposure.
Advice to physicians:
Medetomidine is an alpha2-adrenoreceptor agonist. Symptoms after absorption may
involve clinical effects including dose-dependent sedation, respiratory depression,
bradycardia, hypotension, a dry mouth, and hyperglycaemia. Ventricular arrhythmias
have also been reported.
Respiratory and haemodynamic symptoms should be treated symptomatically.
Special precautions for the protection of the environment:
Not applicable.
The concomitant administration of other central nervous system depressants should
be expected to potentiate the effect of either product and appropriate dose
adjustment should be made.
Medetomidine has marked anaesthetic sparing effects (see section 3.5 of the SPC).
The dose of compounds such as propofol and volatile anaesthetics should be
reduced accordingly.
The effects of medetomidine can be antagonised by the administration of
atipamezole.
Bradycardia may be partially prevented by prior administration (at least 5 minutes
before) of an anticholinergic agent; however, the administration of anticholinergic
agents to treat bradycardia either simultaneously with medetomidine, or following
sedation with medetomidine, could lead to adverse cardiovascular effects.
Do not refrigerate or freeze.
Keep the vial in the outer carton in order to protect from light.
