Hi Lynn. I'm sorry your vet is providing you with inaccurate information. We have direct purchasing relationships with all of the major manufacturers - it is the same exact medication sold to you by your veterinarian. We only dispense U.S. FDA/EPA approved products, which we unconditionally guarantee 100%. 1-800-PetMeds is a. Pharmacy Verified Website, which you can check here: https://www.safe.pharmacy/buying-safely/#USvets

As with all pharmacies, 1-800-PetMeds' products are inspected by the U.S. Food and Drug Administration. Since we are located in Florida, we are also inspected by the Florida Department of Health. We are in full compliance with both agencies. Also, we are a public company listed on the NASDAQ (Symbol: PETS), so we are subject to very strict reporting and disclosure requirements.
