Are generics safe for dogs and cats?
Yes. FDA-approved generic pet medications must demonstrate bioequivalence to the brand — meaning the same active ingredient reaches the same blood concentration in the same time frame. Clinical effect is expected to be identical.
The only differences between brand Ursodiol (Pets) and generic ursodeoxycholic acid are:
- Manufacturer — different companies produce brand vs generic
- Packaging + inactive ingredients — different fillers, dyes, coatings (all FDA-approved)
- Price — typically 30-60% lower for the generic
A very small percentage of individual pets respond differently to generic vs brand — usually because of inactive ingredient sensitivity, not the active drug. If you notice any change in your dogs and cat's response after switching, consult your vet.
