Please check your prescription, or contact your vet, for the exact amount of medication to order. Your order will be reviewed against your prescription, so if it’s incorrect, it will be declined and a new order will need to be placed. If you don’t have your prescription on hand take your best guess (for example, order one month's supply of medicine). If there are any discrepancies, our Customer Care team will resolve the issue and ensure you are charged correctly and get the correct amount of medication for your pet.
