Do I Need a Prescription to Buy Pet Medication Online in the UK?

Veterinarian prescribing medication for a dog in a veterinary clinic

Pet owners in the UK are increasingly buying medication for their dogs and cats online. A common question is whether a veterinary prescription is required.

The answer depends on how the medicine is classified under UK veterinary medicines regulations.

Veterinary medicines generally fall into three main categories:

  • POM-V – Prescription Only Medicine, Veterinarian
  • POM (Cascade) – medicines prescribed under the veterinary cascade
  • NFA-VPS / AVM-GSL – medicines that do not require a prescription

Prescription Only Medicines (POM-V)

Examples of prescription only veterinary medicines

POM-V medicines are veterinary medicines that can only be supplied with a prescription written by a veterinary surgeon.

Before prescribing these medications, a vet must examine the animal and confirm that the medicine is appropriate for the condition being treated.

Examples of POM-V medicines include treatments used for:

  • Heart disease
  • Epilepsy and seizure disorders
  • Thyroid disease
  • Chronic pain and arthritis
  • Allergic skin disease

If you are using an online veterinary supplier, the supplier must receive and verify a valid prescription before the medication can be supplied. You can read more about how prescriptions are handled in our prescription policy.


POM (Cascade) Medicines

Sometimes a suitable licensed veterinary medicine does not exist for a particular condition.

In these situations, veterinarians may prescribe medicines under the veterinary cascade. This allows vets to prescribe alternative medicines when no authorised veterinary product is available.

Cascade prescriptions may include:

  • Human medicines used in animals
  • Veterinary medicines licensed for a different species
  • Compounded medicines prepared for an individual patient

You can learn more about how this system works in our guide to cascade and off-label veterinary medicines.


Medicines That Do Not Require a Prescription

Examples of non prescription veterinary medicines

Some veterinary medicines can be supplied without a prescription. These medicines are typically classified as NFA-VPS or AVM-GSL.

Examples of products that may not require a prescription include:

Although these medicines do not require a prescription, they should still be used according to veterinary advice or product instructions.


Buying Veterinary Medicines Online

UK pet owners are legally allowed to purchase veterinary medicines from online suppliers, provided the supplier follows UK regulations and receives a valid prescription for POM-V medicines.

If you're considering using an online supplier, it is helpful to understand how they operate and how they compare with veterinary practices. Our article on choosing an online veterinary supplier explains what to look for.

You may also notice that medication prices vary between veterinary clinics and online suppliers. This is explained in more detail in our guide to why veterinary drug prices vary.


Summary

Whether a prescription is required to buy pet medication online in the UK depends on how the medicine is classified.

  • POM-V medicines require a veterinary prescription.
  • Cascade medicines are prescribed when no licensed veterinary medicine is available.
  • NFA-VPS and AVM-GSL medicines can usually be supplied without a prescription.
