Key differences
- How you get them differs: Librela is prescription, given at the clinic; Carprofen is prescription.
- A clinic-given medicine means a trip to the vet each time, which adds visit fees but takes the daily pill off your plate.

That is a call for your vet. They weigh your pet's age, weight, other health problems, other medicines and what you can realistically give at home.
Switching from Librela to Carprofen is common, but do it only with your vet's plan.
