Common Prescription Medicines for Dogs in the UK: Uses, Costs & How to Save
Updated: 2 days ago
If your dog needs regular medication, the cost can quickly become another significant part of owning a pet.
Prescription medicines for dogs can be used to manage everything from arthritis and allergies to heart conditions, seizures and infections. Some treatments may only be needed for a short period, while others can be required for months or even for the rest of a dog's life.
But you don't necessarily have to buy prescription medication directly from your vet.
In the UK, you can ask your vet for a written prescription and use it to purchase suitable prescription veterinary medicines from an appropriately registered supplier.
A written prescription is required when the medicine is being supplied by a separate business from the one that prescribed it.
That can make comparing prices particularly worthwhile for dogs requiring ongoing medication.
In this guide, we'll explain some of the common types of prescription medicine used for dogs in the UK, what they're generally used for, how medication costs can build up and how to compare prices safely.
Important: This guide is about understanding costs and purchasing prescribed veterinary medicines. It isn't a guide to choosing medication for your dog. Prescription medicines should only be used as directed by your vet.
Can You Buy Your Dog's Prescription Medicine Online?
Yes.
If your vet has prescribed an appropriate medicine, you can ask for a written prescription and potentially have that prescription dispensed by another authorised supplier instead of buying the medicine directly from the veterinary practice.
This can be particularly useful when your dog needs repeat medication.
Online sellers supplying prescription veterinary medicines in the UK must be registered with the Veterinary Medicines Directorate (VMD), and the VMD maintains a register of online retailers.
💰 Compare the total cost
Don't compare the medicine price alone.
Consider:
Vet prescription fee + medicine price + delivery charge
against the price your veterinary practice charges for supplying the medication directly.
For long-term medication, even a relatively small saving on each repeat prescription can become significant over a year.

Common Prescription Medicines for Dogs
There are many different veterinary medicines, and the appropriate treatment depends entirely on the condition, the individual dog and your vet's assessment.
However, owners may come across some of the following names and types of medication.
1. Arthritis and Anti-Inflammatory Medication
Arthritis is a common reason for dogs to require long-term treatment.
Veterinary medicines used to manage pain and inflammation can include NSAIDs such as meloxicam and carprofen, although the appropriate treatment varies between dogs.
Because arthritis is usually a long-term condition, the cumulative cost of medication can be more important than the price of a single pack.
A dog requiring medication every month could potentially need 12 repeat supplies every year, making this one area where comparing legitimate pharmacy prices may be worthwhile.
2. Allergy and Itch Medication
Persistent itching and allergic skin disease can also result in ongoing veterinary costs.
Depending on the diagnosis, vets may use treatments including oclacitinib (Apoquel) or other prescription therapies. Some dogs require ongoing management rather than a single course of treatment.
That means owners should consider the monthly or annual cost rather than simply the cost of the first prescription.
Medication isn't interchangeable, however. Don't switch products, doses or treatments simply because another option appears cheaper online — discuss alternatives with your vet first.
3. Heart Medication
Dogs diagnosed with certain heart conditions may require medication for an extended period.
One name owners may encounter is pimobendan, including veterinary products such as Vetmedin, although heart treatment can involve different medicines depending on the condition.
For a dog requiring medication continuously, even modest differences in dispensing cost can accumulate over time.
This makes heart medication another category where asking your vet about a written prescription and comparing authorised suppliers can be worthwhile.
4. Seizure and Epilepsy Medication
Dogs diagnosed with epilepsy or recurring seizures may be prescribed long-term medication.
Veterinary treatments can include medicines containing phenobarbital or imepitoin, depending on the individual case and veterinary assessment.
Long-term treatment may also involve veterinary monitoring and blood testing, meaning the medication itself isn't necessarily the only cost.
5. Antibiotics
Antibiotics may be prescribed for bacterial infections where your vet considers them appropriate.
Unlike many long-term medications in this guide, antibiotics are often prescribed as a defined course of treatment.
The medicine, dose and duration depend on the infection and the individual animal.
Antibiotics should be given exactly as instructed by your vet and shouldn't be saved for future illnesses or given to another pet.
For a short one-off course, obtaining a separate prescription purely to shop elsewhere may not always produce a meaningful saving once prescription and delivery charges are considered.
6. Thyroid Medication
Dogs with certain thyroid conditions can require ongoing medication and monitoring.
Because treatment may continue long term, owners can end up purchasing the same prescribed medicine repeatedly throughout the year.
That makes it another area where comparing the annual cost rather than simply the cost of one pack makes sense.
Ask your vet how frequently your dog will need reviews, monitoring or blood tests as these should also be included when budgeting for treatment.
7. Prescription Flea and Worm Treatments
Not every flea and worm product requires a veterinary prescription.
Some parasite treatments can be purchased without one, while others fall into different veterinary medicine categories and may require professional prescribing or supply.
We've covered this separately because there are potentially substantial savings available when buying routine parasite treatments.
How Much Do Dog Prescription Medicines Cost?
There isn't a useful single average because the price depends on:
The medicine prescribed
Strength and dosage
Your dog's weight
Pack size
Length of treatment
Brand or authorised alternative prescribed
Where the medicine is dispensed
Prescription fees
Delivery charges
Required veterinary reviews or monitoring
For short courses, the difference between suppliers may be relatively small.
For medication required every month, however, comparing the annual cost can be much more useful.
For example, saving £10 on medication purchased every month would equal £120 over a year.
That's why long-term prescription costs deserve more attention than one-off purchases.
Do Vets Charge for Written Prescriptions?
Veterinary practices can currently charge for providing a written prescription.
Changes following the Competition and Markets Authority's veterinary-market investigation will introduce a maximum fee of £21 for the first medicine prescribed during a consultation and £12.50 for each additional medicine prescribed during the same consultation.
However, these requirements are being phased in. Large veterinary businesses are due to comply with the prescription-fee cap from March 2027, with small businesses required to comply with the measures by September 2027.
So, during the transition, check what your own veterinary practice currently charges.
Is Buying Pet Medication Online Safe?
It can be, but use an appropriate UK supplier.
Businesses selling POM-V, POM-VPS and NFA-VPS veterinary medicines online must be registered with the Veterinary Medicines Directorate, and registered retailers are listed on the VMD's online register.
Never choose a medicine simply because you've found it cheaper online.
Your vet determines what is appropriate to prescribe; your opportunity as the owner is to decide where to have that prescription dispensed, where the rules allow.
How to Save Money on Dog Medication
There are several sensible ways to reduce medication costs without compromising veterinary care:
Ask what your vet charges for a written prescription.
Compare the total cost of buying from your vet against an appropriately registered online supplier.
For ongoing treatment, compare the annual cost, not just one month's medication.
Ask whether the prescription can cover repeat supplies where clinically appropriate.
Factor in delivery charges before deciding which option is cheaper.
Never change dosage, stop treatment or substitute medication purely to save money without speaking to your vet.

Don't Forget the Other Costs of Treatment
Medication is often only one part of the bill.
A dog receiving long-term treatment may also require consultations, blood tests, diagnostic imaging or regular monitoring.

Final Thoughts
Prescription medication can become a significant ongoing expense, particularly when a dog needs treatment for a long-term condition.
The important distinction is that your vet prescribing a medicine doesn't necessarily mean you must purchase that medicine from the same veterinary practice.
For suitable prescription medicines, asking for a written prescription and comparing the total cost from appropriately registered suppliers can help reduce ongoing costs. The saving is most likely to matter for medicines purchased repeatedly over months or years.
Always follow your vet's instructions and use properly registered suppliers when purchasing veterinary medicines online.
