Do I need a prescription for Bravecto or NexGard?

Most UK online pharmacies require a prescription for isoxazoline-class oral parasiticides (Bravecto, NexGard, Credelio, Simparica) because they are POM-V. Some sell to existing customers under the SQP (suitably qualified person) route. Ask your vet for a written prescription or buy through a pharmacy that has an in-house SQP.

Is Moxiclear really the same as Advocate?

Yes. Moxiclear is generic imidacloprid + moxidectin (Norbrook). Same active ingredients, same coverage, generic pricing. It is fully VMD-approved.

Why does my vet keep recommending the most expensive parasiticide?

Practice protocols often default to one preferred brand for stocking efficiency. From 23 September 2026 the CMA Order requires practices to tell clients that medication is often cheaper online and to disclose cheaper alternatives. Ask your vet to write the prescription generically wherever possible.

Indicative, May 2026

Parasiticides are the single biggest source of vet practice mark-up flagged by the CMA. Every UK practice stocks them, dispenses them at standard intervals, and applies a substantial dispensing margin to every dose. The CMA's 2026 Final Report singled them out by name.

For a typical medium dog on monthly flea/tick + monthly all-in-one wormer + tick collar, the annual cost at a vet practice runs to £350-£500. The same products from a VMD-approved online pharmacy come to £150-£250. The CMA's own number for typical owner overspend is £200 a year — that figure is mostly parasiticides.

Notable savings include generic spot-ons (Moxiclear instead of branded Advocate at roughly half the price), monthly chewables (Credelio, Simparica, NexGard all 35-50% cheaper online) and 8-month tick collars (Seresto at around £28-£32 online versus £40-£55 in clinic).

Because most parasiticides are sold without a written prescription, you do not even need to navigate the CMA's prescription rules. Just buy the same product from the cheaper pharmacy.
