Buying pet medication from online pharmacies can save 40–70% compared to vet practice prices. But with many pharmacies to choose from, which ones offer the best prices, service, and reliability? We have compared the leading UK options.
What to Look For
Always check that an online pet pharmacy is:
- VMD-registered: The Veterinary Medicines Directorate regulates who can sell veterinary medicines. Registered pharmacies are inspected and must comply with regulations
- Based in the UK: Overseas pharmacies may sell products not licensed for the UK market
- Staffed by qualified professionals: Must have a pharmacist and/or SQPs (Suitably Qualified Persons) on staff

How to Compare
Prices vary between pharmacies and change frequently. The cheapest pharmacy for one product may not be cheapest for another. For the best value:
- Check prices on VetCost's medication comparison tool
- Factor in delivery costs (some offer free delivery above a threshold)
- Check for multi-buy discounts (e.g., 6-pack vs 3-pack)
- Sign up for email alerts on price drops
The Prescription Process
For POM-V medications, most pharmacies require you to:
- Place your order online
- Post the original written prescription to the pharmacy
- The pharmacy verifies and dispenses the medication
- Delivery in 1–3 working days after prescription is received
Some pharmacies now accept electronic prescriptions sent directly from the vet, speeding up the process considerably.
