Omeprazole for Dogs and Cats: Uses & How It’s Prescribed in the UK

Omeprazole is commonly prescribed for dogs and cats to help manage stomach acid, reflux, and gastrointestinal conditions. If your pet has been recommended omeprazole by your vet, you may be wondering how it works and how it is obtained safely and legally in the UK.

What is omeprazole used for in dogs and cats?

Omeprazole is a proton pump inhibitor (PPI) that reduces the amount of acid produced in the stomach. In veterinary medicine, it is widely used to protect the gastrointestinal tract and manage acid-related conditions.

It may be prescribed for:

• Acid reflux and oesophagitis
• Stomach and intestinal ulcers
• Chronic vomiting or bile vomiting syndrome
• Gastritis and gastrointestinal irritation

It is often used alongside other treatments depending on the underlying condition and should only be given under veterinary supervision.

How do I get omeprazole for my pet?

Example packaging of omeprazole (human medication used under the veterinary cascade)

Because omeprazole is used under the veterinary cascade, it must follow a regulated process:

1. Veterinary assessment

Your vet must assess your pet and determine that omeprazole is appropriate based on their symptoms and diagnosis.

2. A written prescription

Your vet can either provide the medication directly or issue a written prescription.

3. Supply against a valid prescription

The medication is then supplied in accordance with UK regulations against a valid veterinary prescription.

Why is omeprazole only available under the veterinary cascade?

Omeprazole is not licensed for veterinary use in the UK and is prescribed under the veterinary cascade. This allows vets to use human medicines where appropriate to manage acid-related gastrointestinal conditions.

Medicines supplied under the cascade must be prescribed by a veterinary surgeon and supplied in accordance with UK regulations.

Where can omeprazole be obtained?

Once you have a valid prescription, omeprazole may be obtained from:

• Your veterinary practice
• A UK-registered supplier operating in accordance with veterinary medicines regulations

All legitimate suppliers must follow strict UK regulations set by the Veterinary Medicines Directorate (VMD) and the Royal College of Veterinary Surgeons (RCVS).

Why do prices vary between providers?

You may notice that the cost of omeprazole differs between providers due to sourcing, overheads, and supply models.
