General Pet Prescription Questions

1. Why Do Pets Need Prescriptions?

Pets need prescriptions to ensure they receive the right medication, at the right dose, for the right condition.

When your vet gives you a prescription for your pet, it means they have decided the prescribed medication is necessary to treat your pet’s medical condition.

2. Can I Buy Pet Meds Without a Vet Prescription?

Some pet medications (such as flea and worm treatments or basic supplements) are available over the counter.

However, Prescription Only Medicines – Veterinary (POM-V) can only be supplied with a vet’s approval. These are often used for treating conditions requiring close monitoring and can be prescribed after the vet has examined your pet.

Buying unlicensed or imported products online can be risky, as they may be counterfeit or dangerous for your pet.

3. What Types of Pet Medicines Require a Prescription?

Prescription-only pet medicines are those that could cause harm if misused or that treat complex health conditions. Examples include:

Antibiotics and anti-infectives (penicillin, enrofloxacin, etc.)
Pain relief and anti-inflammatory drugs (meloxicam, carprofen)
Seizure control medication (see our guide on epilepsy in cats and dogs)
Behavioural or anxiety medicines
Chronic condition medication (for heart failure, diabetes, thyroid disorders, etc.)
Prescription tick, worm, and flea products (see here how to protect your pet from fleas)

4. Can Pets Take Human Medicine?

No, pets should generally not take human medicine unless explicitly prescribed by a vet.

Some medicines are the same for humans and pets. However, in many cases, even small doses of human medications (e.g., painkillers such as paracetamol or ibuprofen) can be highly toxic to pets.

Never give your pet human meds without explicit veterinary direction.

5. Why Are Pet Prescriptions So Expensive?

Key reasons affecting the cost of pet prescriptions include:

Pet meds are produced in smaller quantities than human drugs.
They undergo specialised testing for animal use.
Many pet insurance policies don’t cover routine medications.
Vets include consultation, diagnosis, and follow-up costs.

To save money, you can ask your vet for a written prescription and then buy the medication from a registered UK pet pharmacy.

6. Can a Vet Refuse to Give Me a Prescription?

Vets can’t refuse to give you a prescription if you request one, provided the animal is under their care and has been clinically assessed.

7. What Information Should Be on a Pet Prescription?

A valid veterinary prescription should include:

Veterinarian details (name, address, phone number, signature)
Client/pet information (name of pet owner, pet’s name and species)
Medication specifics (med name, strength, dosage, quantity)
Safety information (necessary warnings, such as “for animal treatment only”)
Date of issue and validity period

8. Can I Use a Pet Prescription at Any Pharmacy?

Yes, most licensed pharmacies can fill a veterinary prescription if they are registered with the Veterinary Medicines Directorate (VMD).

However, always ensure the pharmacy is reputable and compliant with UK regulations.

Arthritis and joint pain
Dental problems
Diabetes

10. Why Do Dogs Need Heartworm Medication?

Heartworm (Dirofilaria immitis) is a serious, potentially fatal parasitic disease caused by worms that usually live in the heart or lungs.

Heartworm medication is necessary for the following reasons:

Dirofilaria immitis can be fatal if left untreated.
Medication prevents permanent damage.
The risk of infection is high, as mosquitoes can easily enter homes and transmit the disease.

11. Do Dogs Really Need Flea & Tick Medicine in Winter?

Yes, dogs generally need flea and tick medicine in winter. While extreme cold can kill parasites, many of them can survive in indoor environments (especially fleas, which thrive in warm conditions).

That’s why regular and year-round treatment is necessary to avoid infection and allergic reactions.

12. Can I Give My Dog Cat Medicine?

No, you shouldn’t give your dog cat medicine. Some antibiotics may be shared between dogs and cats, but dosages differ significantly, while many cat-specific products can be ineffective or even harmful to dogs.

13. Why Do Dogs Hate Pills? And How Can I Help?

Many dogs refuse to take pills due to:

Bitter taste or smell
Fear due to previous bad experiences (e.g., gagging)
Texture
Difficulty swallowing (for large pills)

To help your dog take pills:

Hide them in smelly food or food they can’t resist (peanut butter, cream cheese, etc.).
Use pill pockets.
Use the “double treat” method. Give your dog a treat without a pill, then give them a treat with the pill.

Always confirm whether a medicine can be taken with food before disguising it.
