How long a prescription for antimicrobials will be valid
A prescription for antimicrobials is valid for five days from date of issue and must be filled within this timeframe. You can treat the animals for as long as is specified by the vet on the prescription.
How long existing prescriptions for specific antimicrobials will be valid
Any existing prescriptions that you have for specific antimicrobials like intramammary tubes for cows will no longer be valid from 2 February 2022. You will need to contact your veterinary practitioner to get a new prescription.
How long a prescription for all other veterinary medicines will be valid
A prescription for all other veterinary medicines that are not antimicrobials can be valid for a maximum of 12-months.
Changes for vets prescribing antimicrobials
The new regulation requires that antimicrobials are not used routinely or to compensate for poor hygiene, inadequate animal husbandry or poor farm management.
After January 2022, antimicrobials are only allowed for prophylaxis in 'exceptional cases' for administration to an individual animal or restricted number of animals when the risk of infection is very high and consequences are likely to be severe. In the event of an antibiotic being used in 'exceptional' cases for prophylaxis, it will all be limited in quantity and duration to the treatment to cover the risk of an individual animal.
After January 2022, a prescription for antimicrobials for metaphylaxis may only to be issued after diagnosis of infection, when the risk of spread of an infection is high and when no other appropriate alternatives are available.
Antimicrobials will be prescribed by vets acting within a Client-Patient-Practice-Relationship (CPPR) in line with the Veterinary Council of Ireland’s Code of Professional Conduct for Veterinary Practitioners.
Veterinary medicines you can have on your farm
There can be a small quantity of medicines on a farm that are essential to protect animal health and welfare. Prescription Only Medicines (POM) can only be present if a vet deems them necessary. It is for your vet to justify the veterinary medicines they have prescribed for your animals. In the case of prescription only antimicrobial medicine, a vet can only prescribe a small quantity of antimicrobials to be kept on farm where there may be an essential need for the administration to an individual animal or restricted number of animals when the risk for infection, or an infectious disease is very high or its consequences are likely to be severe. Contact your vet for further details.
Changes that take effect on veterinary medicines from 1 December 2022 in Ireland
The requirement to only supply antiparasitic medicines on foot of a veterinary prescription is deferred until 1 December 2022. A prescription will not be required for such products until that date. This is to allow the necessary business and/or infrastructural adjustments that will ensure compliance and the Regulations will apply in full from 1 December 2022.
The new National Veterinary Prescription System (NVPS) is in place since January 2022. It is available for voluntary use by vets to ensure prescribers and dispensers are familiar with the system when it becomes compulsory on 1 December 2022. Veterinary practitioners can continue to issue paper-based prescriptions until then.
When the changes for antiparasitics for food producing animals take effect
The implementation date of the prescription requirement for antiparasitics is now 1 December 2022.
From 2022, your vet will need to write you a prescription to get antiparasitics for food-producing animals. The time limit on a valid prescription for these products will be 12 months. Antiparasitic medicines can then be purchased by your preferred supplier in the timeframe of the valid prescription.
Guidance for deferral of changes to antiparasitics
Further Guidance to Veterinary Medicinal Products Industry on elements of the Roadmap to Implementation of EU2019/6
The following guidance is bring provided to assist industry and provide further clarity on the practical implementation surrounding the decision announced to defer the requirement to only supply antiparasitic medicines for food-producing animals under prescription until December 1 2022.
Measures permitted until December 1 2022:-
1. Antiparasitics for food-producing animals can be supplied without prescription.
2. Antiparasitics for food-producing animals can continue to be sold online and at a distance.
3. Antiparasitics for food-producing animals can continue to be advertised.
4. Antiparasitics for food-producing animals can continue to be on display in retail premises.
These interim measures should provide adequate time to allow industry to move to full compliance by December 1 2022.
On that date there must be no supply of antiparasitics without a prescription, they must no longer be advertised, either in print or online, and they must not be on display in a retail premises.
