What Is a Veterinary Prescription?

If your pet has been diagnosed with a health problem or needs a specific treatment, your veterinary surgeon may issue a veterinary prescription. For many pet owners, especially those new to managing a pet’s medication, this can feel a little unfamiliar at first. The good news is that veterinary prescriptions are a normal and important part of safe pet care.

In simple terms, a veterinary prescription is a written instruction from a qualified veterinary surgeon that allows a specific medicine to be supplied for your pet. It helps make sure your dog, cat, or small pet receives the right treatment, in the right dose, for the right condition.

At Vetscriptions, we help UK pet owners access genuine pet medicines and healthcare products with clear guidance on how prescriptions work and how to order safely online.

This article is intended for general guidance only and should not replace professional veterinary advice. If your pet is unwell or showing concerning symptoms, please contact your veterinary surgeon.

What is a veterinary prescription?

A veterinary prescription is a legal document written by a veterinary surgeon after assessing your pet. It authorises the supply of a prescription-only medicine that cannot be sold without veterinary approval.

These medicines are often referred to as prescription-only veterinary medicines, sometimes shortened to POM-V. This simply means they are medicines that must be prescribed by a vet because they need proper diagnosis, careful dosing, and ongoing monitoring where needed.

A prescription may be issued for many different reasons, including:

• Treating an infection
• Managing pain or inflammation
• Controlling a long-term condition such as arthritis, epilepsy, or thyroid disease
• Supporting recovery after illness or surgery
• Providing certain flea, tick, or worm treatments that require veterinary approval

Once a valid prescription has been written, you may be able to order the medication from an authorised UK veterinary pharmacy such as Vetscriptions, rather than buying it directly from your veterinary practice.

Why do some pet medicines need a prescription?

Not all pet medicines are suitable for general sale. Some treatments can cause side effects, interact with other medicines, or be unsafe if used for the wrong condition. A prescription helps protect your pet by ensuring a vet has considered their individual needs first.

This is especially important because symptoms that look similar can have very different causes. For example, itching could be linked to parasites, allergies, skin infection, or another health issue. A prescription ensures treatment is based on a proper clinical decision rather than guesswork.

Prescription control also helps with responsible medicine use, including:

• Reducing the risk of incorrect dosing
• Avoiding unsuitable or unnecessary treatment
• Monitoring long-term medication safely
• Supporting the careful use of antibiotics and other important medicines

What information is on a veterinary prescription?

Although the layout can vary slightly, a veterinary prescription will usually include key details such as:

• Your pet’s name and species
• Your name and address
• The name of the prescribing veterinary surgeon
• The veterinary practice details
• The name of the medicine
• The strength, dose, and quantity
• Directions for use
• The date the prescription was issued

These details are important because they allow the medicine to be checked and dispensed safely. If anything is unclear or incomplete, the pharmacy may need to contact the prescribing practice before the order can go ahead.

When might your pet need a prescription?

Your pet may need a prescription for either a short-term problem or a long-term condition. Some common examples include:

Short-term treatment

A vet may prescribe medication for a temporary issue such as an ear infection, eye problem, skin flare-up, digestive upset, or recovery from surgery. Some of these treatments may sit within categories such as dog ear products, cat eye products, or broader prescription medicines, depending on your pet’s needs.

Long-term medication

Pets with ongoing conditions may need repeat prescriptions. This could include treatment for arthritis, heart disease, epilepsy, thyroid disorders, skin conditions, or urinary problems. In these cases, your vet will usually want to monitor your pet regularly to make sure the medicine is still suitable and working as expected.

Preventative treatment

Some preventative products may also require a prescription, depending on the medicine and your pet’s circumstances. For example, certain parasite treatments for fleas, ticks, and worms are prescription-only. You can explore general options in our flea, tick & worming collection, including products for dogs and cats.

Can you ask your vet for a written prescription?

Yes. In the UK, pet owners can ask their veterinary practice for a written prescription for many prescription-only medicines, provided the vet believes it is clinically appropriate. This gives you the option to obtain the medication from another registered supplier, including an online veterinary pharmacy.

Your practice may charge a fee for writing a prescription, and your pet will usually need to be under the vet’s care. In some cases, your vet may also need to examine your pet again before issuing or renewing the prescription, particularly for long-term treatment.

If you are unsure about the process, our Prescription FAQs can be a helpful place to start.

How does ordering a prescribed pet medicine online work?

Ordering online can be a convenient and cost-effective option for many pet owners, as long as it is done responsibly. At Vetscriptions, we aim to make the process straightforward while keeping pet safety at the centre of everything we do.

In most cases, the process looks like this:

• Your vet examines your pet and decides a prescription medicine is needed
• You request a written prescription from your veterinary practice, if you wish to buy elsewhere
• You place your order with a registered veterinary pharmacy
• You provide the prescription, following the pharmacy’s instructions
• The prescription is checked before the medicine is dispensed

If you are new to this, our guide on how to order a prescription medicine explains the steps in more detail. You may also be asked to complete an animal health form for certain orders.

Why it is important to use prescriptions responsibly

Prescription medicines should only ever be used for the pet they were prescribed for, and exactly as directed by the veterinary surgeon. Even if two pets seem to have similar symptoms, it does not mean the same medicine is safe or suitable for both.

To use pet prescriptions responsibly, remember to:

• Follow the dosage instructions carefully
• Complete the full course if your vet advises it
• Never share medicines between pets
• Check expiry dates before use
• Store medicines according to the label instructions
• Contact your vet if side effects, missed doses, or new symptoms occur

If your pet is already taking supplements or other healthcare products, it is also sensible to mention this to your vet. Even supportive products, such as items from our premium supplements range, should be used as part of an informed healthcare plan.

What if your pet’s condition changes?

A prescription is based on your pet’s condition at the time your veterinary surgeon assessed them. If your pet gets worse, develops new symptoms, refuses food, becomes unusually tired, or seems distressed, it is important not to rely on old medication or repeat treatment without advice.

Instead, contact your veterinary surgeon promptly. Ongoing or worsening symptoms may mean your pet needs a re-check, a different medicine, or further tests.

This is particularly important for:

• Breathing problems
• Seizures
• Severe vomiting or diarrhoea
• Difficulty passing urine
• Sudden weakness or collapse
• Suspected pain that is not improving
