According to a recent report by Veterinary Information Network (VIN), "anti-itch" drugs purchased from allegedly deceptive websites have sent several pets into veterinary clinics with serious health complications.
The website "WagLabs" purported to sell the powerful immunosuppressant cyclosporine, which typically can only be obtained through a veterinarian prescription. One pet owner reported giving the WagLabs medication to his dog; soon after, his pet became lethargic and developed extreme thirst, a ravenous appetite, and increased urination. Upon further inspection, bloodwork showed an alarming elevation of liver enzymes, indicating possible liver damage. Testimonies on the website Trustpilot, a review platform, further allege that several dogs experienced "terrible side effects" after taking the WagLabs capsules, with one going into "major organ failure" and needing to be euthanized.
Due to the extreme side effects, there is reason to doubt that the product was actually—or only—cyclosporine.
VIN News further reports that another website called Millionaire Mutt is suspected to be run by the same entity behind WagLabs. Millionaire Mutt sold "oclacitinib chewable tablets," a product mimicking another strong immunosuppressant that can only be obtained via veterinarian. The websites seem to have reached some buyers by running targeted advertisements on Facebook offering allergy relief for dogs.
The American College of Veterinary Dermatology filed a complaint against WagLabs with the U.S. Food and Drug Administration; about a month later, the supposed "cyclosporine" product has been removed from the website. The "oclacitinib chewable tablets" no longer exist on Millionaire Mutt, either.
If you are a pet owner searching for allergy relief for your dog, please do not start your pet on any medications or supplements without consulting your veterinarian first. Do not automatically trust that the products you see online will be safe for your pet to consume, and purchase medications only through verified pharmacies.
