This item is a prescription-only animal medicine, & is only able to be dispensed by us when you have a valid veterinary prescription from your vet, which you will need to post in to us, please proceed to the checkout.A vet prescription is required for the medicine you have chosen. If you do not yet have a prescription then you can print out the following blank veterinary Prescription Form which you can ask your vet to fill in when you next visit. Please note that changes to legislation in 2005 means that Vets must offer you a prescription to take away & not just supply you the medicines directly. This is to ensure more competition & lower prices for you.
