Some foreign internet veterinary pharmacies are fronts for unscrupulous businesses operating against the law.
A veterinarian should physically examine an animal prior to making a diagnosis to determine the appropriate therapy. A foreign or domestic pharmacy may claim that one of its veterinarians on staff will “evaluate” the pet after looking over a form filled out by the pet owner, and then prescribe the drug.
“A veterinarian should physically examine an animal prior to making a diagnosis to determine the appropriate therapy,” says Hartogensis.
CVM (Center for Veterinary Medicine) is especially concerned that pet owners are going online to buy two types of commonly used prescription veterinary drugs—nonsteroidal anti-inflammatory drugs (NSAIDs) and heartworm preventives.
“Both drugs can be dangerous if there is no professional involvement,” says Hartogensis. “It’s not generally a concern if the owner uses a legitimate online pharmacy and mails in a prescription from their veterinarian, who is monitoring the animal. But if there is no veterinarian–client–patient relationship, it’s a dangerous practice.”
NSAIDS and Heartworm Preventives
Veterinarians often prescribe NSAIDs to relieve pain in dogs. NSAIDs should not be purchased on the Internet without a veterinarian’s involvement because:
- Dogs should undergo blood testing and a thorough physical examination before starting NSAIDs
- Dogs should be monitored by a veterinarian while they are taking NSAIDs
- Veterinarians should discuss possible side effects of NSAIDs with the owner
- The prescription should be accompanied by a Client Information Sheet that explains important safety information to the owner
Heartworm disease is a potentially fatal condition transmitted by the bite of a mosquito that is carrying infected larvae of the heartworm parasite. Dogs, cats, and ferrets can get heartworm. Heartworm preventives, given daily, monthly, or semiannually depending on the product, kill the larvae before they become adult worms.
The American Heartworm Society recommends
- Using heartworm medication for dogs year-round, no matter where you live in the United States
- Getting dogs tested yearly to make sure they’re not infected with heartworm
“Testing is important even in dogs regularly treated with heartworm preventive products due to the occasional reports of product ineffectiveness,” says Hartogensis. An Internet pharmacy veterinarian cannot draw blood from the animal to perform the test. If the test isn’t done, a pet owner could be giving heartworm preventives to a dog that has heartworms, potentially leading to severe reactions.
