Paying less for Propofol

  1. 1

Clinical information

Norofol 10 mg/ml Emulsion for Injection for Cats and Dogs — SPC Details

Source: VMD Summary of Product Characteristics (SPC). Last updated 27 Mar 2026.

Norofol Injection is indicated for use in dogs and cats as a short-acting, intravenous
general anaesthetic for procedures of short duration, lasting up to 5 minutes; for the
induction and maintenance of general anaesthesia using incremental doses to effect;
for the induction of general anaesthesia where maintenance is provided by inhalation
anaesthetics.
The product is indicated for intravenous administration to dogs and cats. The vial
should be shaken thoroughly before opening. The product should be inspected
visually for the absence of visible droplets or extraneous foreign particles and
discarded if present.
Induction: The induction dose is calculated according to bodyweight and may be
administered to effect over a period of 10 to 40 seconds. The induction dose is
reduced by the use of premedicants.
Where animals have been premedicated with an -2 agonist such as medetomidine,
the dose of propofol (as with any other intravenous anaesthetic agent) should be
reduced by up to 85% (e.g. from 6.5 mg/kg for unpremedicated dogs to 1.0 mg/kg for
dogs premedicated with an 

Maintenance: Where anaesthesia is maintained by incremental injections, the dose
rate will vary between animals. Incremental doses should be given to effect. Doses of
approximately 1.25 – 2.5mg (0.125 – 0.25ml) per kg bodyweight sustain anaesthesia
for periods of up to 5 minutes.
Maintenance by inhalation agents: Where inhalation agents are used to maintain
general anaesthesia, clinical experience indicates that there may be a need to use a
higher initial concentration of inhalation agent than is normally the case following
induction with barbiturate agents such as thiopentone.
Continuous and prolonged exposure may lead to slower recovery, particularly in cats.
Do not use in animals that are hypersensitive to the active substance or any of the
excipients.
Side effects during induction, maintenance and recovery are uncommon. Induction is
generally smooth, minimal evidence of excitation has been observed in a small
proportion of animals. During the recovery phase, vomiting and evidence of excitation
have been observed in a small proportion of animals. As with other anaesthetic
agents, the possibility of respiratory and cardiovascular depression should be
considered.
In clinical trials in cats, transient apnoea during induction and paw/face licking
characteristics during recovery have been observed in a small proportion of animals.
In clinical trials in dogs, transient apnoea during induction and maintenance have been
observed.
If panting is evident before induction, it may continue throughout the subsequent
periods of anaesthesia and recovery.
Inadvertent perivascular administration rarely causes local tissue reactions.
Repeated anaesthesia with propofol in cats may cause oxidative injury and Heinz body
formation. Recovery may also be prolonged. Limiting repeated anaesthesia to
intervals of more than 48 hours will reduce the likelihood.
If Norofol Injection is injected very slowly, an inadequate plane of anaesthesia can
occur.
Shake the vial gently but thoroughly before opening. Do not use if evidence of phase
separation remains after gentle shaking.

(i)
During induction of anaesthesia, mild hypotension and transient apnoea, similar to
effects with other intravenous anaesthetic agents may occur.
If the product is injected too rapidly, cardiopulmonary depression may occur (apnoea,
bradycardia, hypotension).
When using Norofol Injection, facilities for the maintenance of a patent airway, artificial
ventilation and oxygen enrichment should be available.
As with other intravenous anaesthetic agents, caution should be exercised in dogs and
cats with cardiac, respiratory, renal or hepatic impairment, or in hypovolaemic or
debilitated animals.
Sighthounds may have a slightly longer duration of recovery from anaethesia
compared to other breeds of dog.
Use aseptic techniques when administering the product as it does not contain an
antimicrobial preservative.
(ii)
medicinal product to animals
This is a potent drug: particular care should be taken to avoid accidental self-
administration. A guarded needle should preferably be used until the moment of
injection.
Wash off splashes from the skin and eyes immediately.
In case of accidental self-injection, seek medical advice immediately and show the
package leaflet or the label to the physician.
Advice to Doctor:
symptomatic and supportive treatment.
Propofol has been used in association with commonly used premedicants e.g.
atropine, acepromazine, diazepam; inhalational agents e.g. halothane, nitrous oxide,
enflurane and analgesic agents e.g. pethidine, buprenorphine. No pharmacological
interactions have been encountered.
The emulsion should not be mixed with other therapeutic agents or infusion fluids prior
to administration.
Do not store above 25°C.
Do not freeze.
Protect from light.
Keep the container in the outer carton.
Store vials in the upright position.
Not applicable.
