If the item requires a prescription, it will be indicated on the website. If your pet has been seen at SingVet, a staff will go through your account to see if the requested item has been approved for sale. If your pet has not been seen at SingVet, an original copy of the prescription is required. This has to be presented before the order can be confirmed. Alternatively, you can get your Veterinarian to call in a prescription to SingVet. Most clinics are able to send a prescription over to SingVet.
