Paying less for Propofol

  1. 1

    Ask your vet for a written prescription

    They must provide one on request. Under the CMA Order the fee is capped at £21 from 2027.

  2. 2

    Fill it at a registered online retailer

    The CMA found online pharmacies 50–60% cheaper than practice dispensing on common medicines — typically £200–£300 a year.

Prescription required

Your vet must provide a written prescription on request. You can then purchase from any licensed online retailer.

Induction and maintenance of general anaesthesia by administration of incremental
doses to effect.
Induction of general anaesthesia, where maintenance is provided by inhalation
anaesthetic agents.

Shake gently prior to use.
Dose requirements can vary significantly between individual animals and are
influenced by a range of factors (please refer to section 3.5 Special precautions
for safe use in tartget species, and section 3.8 Interaction with other medicinal
products and other forms of interaction).
drugs (premedication) may markedly reduce propofol requirements dependent on the
type and dose of pre-anaesthetic drugs used.
The dose to be administered should be estimated based on average dose
requirements in preparation for anaesthesia. The actual dose requirements of an
individual animal may be significantly lower or higher than the average dose.
Induction
The induction dose of the veterinary medicinal product presented in the table below
is based on data taken from controlled laboratory and field studies and is the average
amount of drug required for dogs or cats to be successfully induced for anaesthesia.

AN: 03467/2024 & 03468/2024Page 6 of 9
The actual dose administered must be based and titrated on the individual
clinical response of each animal.

* Induction doses significantly below the average dose may be effective after
premedication with an alpha-2 adrenoceptor based protocol in some animals.
The dosing syringe should be prepared based on the dose volume of veterinary
medicinal product shown above, calculated based on bodyweight. The dose should
be administered slowly to effect and administration should continue until the clinician
is satisfied that the depth of anaesthesia is sufficient for endotracheal intubation. As
a guide the veterinary medicinal product should be administered over a period of 10-
40 seconds.
Maintenance
Where anaesthesia is maintained by incremental injections of the veterinary
medicinal product, the dose rate and duration of effect will vary between animals.
The incremental dose required to maintain anaesthesia is typically lower in
premedicated animals compared with unpremedicated animals.
An incremental dose of approximately 0.15 ml/kg (1.5 mg/kg b.w.) in dogs and of
approximately 0.2 ml/kg (2.0 mg/kg b.w.) in cats can be administered when
anaesthesia becomes too light. This dose can be repeated as required to maintain an
appropriate depth of anaesthesia, allowing 20-30 seconds between each dose to
assess the effect. Each incremental dose should be administered slowly to effect.
Continuous and prolonged exposure (greater than 30 minutes) may lead to slower
recovery, especially in cats.

Maintenance of anesthesia by inhalation agents
Where inhalation agents are used to maintain general anaesthesia, it may be
necessary to use a higher initial concentration of the inhalation anaesthetic than is
normally the case following induction with barbiturate agents.
Please refer also to Section 3.5 Special precaution for safe use in target species.
Do not use in cases of hypersensitivity to the active substance or to any of the
excipients.

Oxydative injury and Heinz body production
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.
The veterinary medicinal product is a stable emulsion.
Do not use if evidence of phase separation remains after gentle shaking.
Prior to use, the veterinary medicinal product should be inspected visually for
absence of visible droplets or extraneous foreign particles or phase separation and
discarded if present.
If the veterinary medicinal product is injected too slowly an adequate plane of
anaesthesia may not be achieved due to failure to reach the appropriate threshold of
pharmacological activity.

Special precautions for safe use in the target species:
During induction of anaesthesia, mild hypotension and transient apnoea may occur.
If the veterinary medicinal product is injected too rapidly, cardiopulmonary depression
may occur (apnoea, bradycardia, hypotension).
When using the veterinary medicinal product, facilities for the maintenance of a
patent airway, artificial ventilation and oxygen enrichment must be available.
Following induction of anaesthesia, the use of an endotracheal tube is
recommended. It is advisable to administer supplemental oxygen during maintenance
of anaesthesia.
Caution should be exercised in dogs and cats with cardiac, respiratory, renal or
hepatic impairment, in hypovolaemic, emaciated, old or debilitated animals.
When propofol is used concomitantly with opioids, an anticholinergic agent (e.g.
atropine) may be used in cases of bradycardia according to the benefit/risk
assessment by the responsible veterinarian. See section 3.8.
Care should be taken when administering the veterinary medicinal product to patients
with hypoproteinaemia, hyperlipidaemia or very thin animals since these animals may
be more susceptible to adverse effects.
Propofol does not have analgesic properties, therefore supplementary analgesic
agents should be provided in cases where procedures are anticipated to be painful.
It has been reported that clearance of propofol is slower and incidence of apnoea is
greater in dogs over 8 years of age than in younger animals. Extra care should be
taken when administering the veterinary medicinal product to these animals, for
example, a lower dose of propofol may be adequate for induction in such cases.
Sighthounds have been reported to show a slower clearance of propofol and may
have a slightly longer duration of recovery from anaesthesia compared to other
breeds of dog.
Use aseptic techniques when administering the veterinary medicinal product as it
does not contain an antimicrobial preservative.

Special precautions to be taken by the person administering the veterinary medicinal
product to animals
Propofol is a potent general anaesthetic drug and particular care should be taken to
avoid accidental self-injection. A guarded needle should preferably be used until the
moment of injection.
In case of accidental self-injection, seek medical advice immediately and show the
package leaflet to the physician, but DO NOT DRIVE as sedation may occur.
People with known hypersensitivity to propofol or any of the excipients should avoid
contact with the veterinary medicinal product.
Avoid contact with the skin and eyes as this veterinary medicinal product can cause
irritation.
Wash splashes from skin or eyes immediately with plenty of fresh water. Seek
medical advice if irritation persists.
Advice to the doctor: Do not leave the patient unattended. Maintain airways and
ensure symptomatic and supportive treatment.
Special precautions for the protection of the environment:
Not applicable.
Propofol may be used in association with premedicants, e.g. atropine, glycopyrrolate,
α-2 agonists (medetomidine, dexmedetomidine), acepromazine, benzodiazepines
(diazepam, midazolam); inhalational agents (e.g. halothane, isoflurane, sevoflurane,

Revised September 2025
AN: 03467/2024 & 03468/2024Page 5 of 9
enflurane and nitrous oxide); and analgesic agents such as pethidine and
buprenorphine.
The concurrent use of sedative or analgesic drugs is likely to reduce the dose of
propofol required to induce and maintain anaesthesia. See section
Do not freeze.
The veterinary medicinal product should be used immediately after opening the vial.
Product remaining in the container should be discarded.
Not applicable.
