Frequently asked questions

What is FRONTLINE Flea Spray used for?
FRONTLINE Flea Spray is used to treat and prevent flea infestations in dogs and cats. It also helps control ticks and biting lice.
How does FRONTLINE Flea Spray work?
It contains fipronil, which spreads over the skin and coat after application. It kills fleas and ticks on contact by targeting their nervous system.
How quickly does it work?
Fleas are usually killed within 24 hours. Ticks are typically killed within 48 hours of contact.
How long does protection last?
Protection against fleas can last up to 2–3 months in cats and up to 3 months in dogs. Tick protection is shorter and may require more frequent treatment depending on risk.
Can puppies and kittens use FRONTLINE Flea Spray?
It is suitable for puppies and kittens from 2 days of age, according to the product label.
Can pets be bathed after treatment?
Avoid bathing for at least 48 hours after application. Frequent washing may reduce the duration of protection.
Do I need a prescription?
FRONTLINE Flea Spray is available without prescription.

Do I need a prescription to buy POM-V pet medicines online?

Yes. POM-V items require a valid prescription from your UK vet.

 Upload your prescription during checkout. 

Photos must be clear. If details are wrong or expired, orders can’t be processed. This is standard across UK pet pharmacies.

No. Under UK law, vets must provide a written prescription if you request one for a POM-V medicine. They may charge a reasonable fee for issuing it, but they cannot refuse. This allows you to choose where to buy your pet’s medication, whether directly from your vet or from a registered UK pharmacy such as Ashcroft 4 Pets.

In the UK, most POM-V prescriptions are valid for 6 months, unless your vet specifies a shorter duration. Prescriptions for Schedule 2 or 3 controlled medicines are usually valid for 28 days and are not repeatable. At Ashcroft 4 Pets, we follow these same UK veterinary guidelines to ensure your pet’s medication is dispensed safely and legally.

At Ashcroft 4 Pets, we are a fully VMD-registered and accredited online retailer. This means every prescription and over-the-counter pet medicine we supply is safe, genuine, and dispensed according to UK law.

We follow all Veterinary Medicines Directorate (VMD) rules, and our team checks every prescription carefully before processing. You can order with confidence, knowing your pet’s health is in the hands of experts and all medicines are traceable, legally supplied, and authentic.

In the UK, most repeat prescriptions for POM-V medicines are valid for up to 6 months from the date your vet issues them. You can order multiple times within this period if your vet has authorised repeats.

For controlled medicines (Schedule 2 or 3), the prescription is valid for 28 days only and cannot be repeated. These medicines are strictly regulated due to their potential for misuse.

At Ashcroft 4 Pets, we follow UK law carefully, ensuring all prescriptions are dispensed safely, legally, and in the exact amounts prescribed.

 If your vet prescribes a human medicine for your pet under the Cascade, we can usually dispense against that prescription (with the right checks).
