Cheapest price per ml across pack sizes, so the biggest pack is often the cheapest per ml. “Typical month” uses a typical amount (Single 15ml bottle; check the label for dosing by weight); your pet’s dose may differ. Prices checked weekly, last on 2 November 2026. Always check the final price, including delivery, before you order.
Often, but not always. Online you pay the medicine price, delivery and your vet’s written prescription fee (typically £27). For a long course, or a medicine your pet takes every month, the saving usually outweighs the fee; for a short course it may not. Ask your practice for its price, then use our medicine savings calculator to compare.
