Who is allowed to dispense POM-Vs and veterinary medicinal products prescribed under the cascade?

Once a veterinary surgeon has met their ‘under care’ obligations pursuant to the Veterinary Medicines Regulations 2013 (as amended), and Chapter 4 of the supporting guidance to the Code of Conduct, they may delegate the dispensing/supply of those POM-Vs or veterinary medicinal products under the cascade to a team member.  In order to do this, the prescribing veterinary surgeon must authorise each transaction individually before it is supplied (see next section for further information) and be satisfied that the person handing it over to the client is competent to do so. For the veterinary surgeon to be satisfied the person dispensing must have knowledge of practice protocols (i.e. trained) and there must be a SOP in place.

The prescribing and delegating veterinary surgeon will remain ultimately responsible, and their responsibilities associated with the prescription and supply of POM-Vs and veterinary medicinal products under the cascade, is set out at paragraphs 4.37 - 4.41 of Chapter 4, as follows:

4.37  A veterinary surgeon or veterinary nurse who is also an SQP who prescribes a POM-VPS veterinary medicinal product, or supplies a NFA-VPS veterinary medicinal product, and a veterinary surgeon who prescribes a POM-V or a veterinary medicinal product under the cascade is required:

  1. before they do so, to be satisfied that the person who will use the product is competent to use it safely and intends to use it for a use for which it is authorised;
  2. when they do so, to advise on the safe administration of the veterinary medicinal product;
  3. when they do so, to advise as necessary on any warnings or contra-indications on the label or package leaflet;
  4. to not prescribe (or in the case of a NFA-VPS product, supply) more than the minimum amount required for the treatment

4.38 The VMRs do not define 'minimum amount' and the RCVS considers this must be a matter for the professional judgement of the veterinary surgeon in the individual case.

4.39 The prescribing veterinary surgeon or SQP is required to be present when POM-Vs, POM-VPS, or NAF-VPS are handed over unless they have authorised each transaction individually before the product is supplied and is satisfied that the person handing it over is competent to do so.

4.40  Veterinary medicinal products must be supplied in appropriate containers and with appropriate labelling.

4.41  It is illegal under the VMRs to use or supply a veterinary medicinal product that has passed its expiry date.

  • What is the maximum amount of a controlled drugs that can be prescribed at one time?

    CDs are subject to additional legal requirements as they have been identified as at risk of abuse or misuse. For acute conditions, the maximum quantity of CDs prescribed should not exceed 30 days’ worth; exceptionally, to cover a justifiable clinical need and after consideration of any risk, a prescription can be issued for a longer period, but the reasons for the decision should be recorded in the animal’s clinical notes.

    If more than 30 days’ worth of treatment is prescribed, the prescribing veterinary surgeon must be sure that the owner is competent to use the medicine safely.

    Please see the Controlled Drugs Guidance – A to Z for more information on prescribing for chronic conditions.

  • Do I need consent when supplying medicines under the Cascade?

    When prescribing under the Cascade, veterinary surgeons should ensure they obtain written consent* for use of that medicine from the client. A consent form template is available from the VDS (which has been reproduced in the RCVS PSS Small Animal module).

    It should be noted it is generally unacceptable for veterinary surgeons to use an all embracing “general” lifelong consent for any and all products provided under the Cascade that might be given to any animal.  Practically, this means specific consent needs to be obtained from a client for each unauthorised medicine used. 

    However, it is acceptable for a lifelong consent form to be used for a specific ongoing condition requiring unauthorised medicine for that particular medicine in that particular animal.  It is also acceptable to use lifetime consent in the case of exotics where there are no licensed products available.

  • What are the main issues regarding labelling Cascade medicines?

    2. The name of the veterinary surgeon who has prescribed the product
    3. The name and address of the animal owner
    4. The identification (including the species) of the animal or group of animals
    5. The date of supply
    6. The expiry date of the product, if applicable
    7. The name or description of the product, which should include at least the name and quantity of active ingredients
    8. Dosage and administration instructions
    9. Any special storage precautions
    10. Any necessary warnings for the user, target species, administration or disposal of the product
    11. The withdrawal period, if relevant
    12. The words ‘Keep out of reach of children’ and ‘For animal treatment only’.
  • What written information should be provided with a split pack of a POM V?

    For a Veterinary Medicine Product supplied in a container other than that specified in the marketing authorisation (e.g. tablets dispensed into smaller containers) the person supplying the product must ensure that the container is ‘suitably labelled’ and must supply sufficient written information for the medicine to be used safely. This legal requirement may be met by:

    • Labelling the product in accordance with the PSS’s requirements (see below) and providing a copy of the package insert or the SPC to the client.
    • Providing the NOAH data sheet, or a link to the data sheet online.
    • Using a dispensing envelope supplied by the drug company, or that includes that practices own written information.

    RCVS PSS requirements for labelling VMPs:
    All POM-V medicines supplied by the practice must be legibly and indelibly labelled with:

    • Name and address of the animal owner
    • Name and address of the veterinary practice supplying the medicine
    • Date of supply
    • Name, strength and quantity of product
    • Dosage and directions for use
    • ‘For animal treatment only’
    • For topical preparations ‘For external use only’.
  • What are the common issues with temperature monitoring?

    In 47% of PSS assessments, assessors found that there was lack of evidence of temperature monitoring for medicines.

    Medicines need to be stored at the correct temperature in accordance with the Summary of Product Characteristics.

    Where medicines are to be stored at ambient room temperature, the temperature should be kept between 8°C and 25°C and should be monitored. This is especially important where the outside temperature is particularly high or low.

    Medicines such as vaccines and insulin need to be refrigerated between 2°C and 8°C. They should only be removed from the refrigerator for immediate use.

    Fridge temperatures should be monitored daily, ideally by the same person, and the results logged, or if monitored by using an electronic data logger these should be alarmed, the alarm checked daily to make sure it has stayed within range and the data downloaded weekly.

    A written standard operating procedure should be in place, detailing the actions to be taken should the temperatures fluctuate outside the recommended limits.

  • What are the common issues with broach dates?

    It is illegal under the VMRs to supply or administer an out of date or expired veterinary medicinal product, including CDs.

    All multi-dose injectables will have an “in use shelf-life” that tells the user how long the vial can be used for, after it has first been broached. It is illegal under the VMRs to use a medicine for longer than this period.

    Multi-dose vials should be marked with the date of first opening, or the date of expiry, and any medicine left in the vial after the specified time must be discarded/denatured. If the medicine is a Schedule 2 CD, denaturing must be independently witnessed.
