All data is sourced from the FDA Center for Veterinary Medicine adverse event reports submitted voluntarily by veterinarians, pet owners, and drug manufacturers. This information has not been independently verified and does not establish that any drug caused the reported outcomes. These reports reflect what was submitted to the FDA, not confirmed cause-and-effect relationships or actual risk rates. Reporting rates may vary by drug, manufacturer, and time period, and may be delayed up to 6 months. The percentage shown represents proportions within the reported dataset and does not indicate risk probability or safety ratings. SafeVetMeds is a 501(c)(3) nonprofit providing data transparency infrastructure and does not provide veterinary medical advice, diagnostic services, or legal counsel. For medical decisions regarding your animal, consult a licensed veterinarian. For legal questions, consult an attorney. This data should be considered as one factor among many in medical decision-making, not as definitive evidence of drug safety or danger.
