Prescribed to dogs: use only as directed

Vets prescribe this for dogs, so being on it is not a problem in itself. This page is about what happens when a dog gets more than it was meant to have.

Carprofen is a veterinary NSAID used for pain and inflammation. A prescribed course can be appropriate while an overdose or an adverse reaction still needs prompt assessment.

Got the amount wrong, or your dog reached the container?

Call the practice that prescribed it: they know the dose your dog is on, which is what decides whether this matters. Out of hours, either line below is open.

Exposure details to have ready

These are the questions a veterinarian or poison-control operator will ask. Fill in what you know and leave the rest blank. This tool does not estimate a dose or a risk score: medication risk depends on the exact ingredient, strength, and formulation, so the assessment has to come from the clinician on the call.

Signs so far
Before you call
  • Keep the package, blister pack, or prescription bottle. The strength and the full ingredient list are what make the advice specific.
  • Do not induce vomiting unless a veterinarian or poison-control professional tells you to. It is the wrong move for several medications and can cause harm on its own.
  • Do not give milk, food, salt, hydrogen peroxide, or any home remedy on your own.
  • Do not give a second dose of anything to make up for one you think was missed.
  • Count what is left in the packet, so the number missing can be worked out.

Why Carprofen (Rimadyl) needs caution

Carprofen is a veterinary NSAID used for pain and inflammation. A prescribed course can be appropriate while an overdose or an adverse reaction still needs prompt assessment. Digestive side effects can occur, and more serious reactions may involve the stomach, kidneys or liver. Other NSAIDs and steroids are important interaction concerns. Report a chewed bottle or suspected extra dose with the tablet strength and prescribed schedule.

Vomiting, diarrhea, reduced appetite or lethargy; bloody vomit, dark stool, increased thirst or urination, or yellowing skin needs prompt care.

FAQ

How much Carprofen (Rimadyl) is dangerous?

This page gives no dose or safe-exposure threshold. Follow the prescription for this dog; ask the veterinarian to confirm the product and any change to the schedule.

Can I treat this at home?

Prevent further access and keep the packaging. Do not induce vomiting or give a home remedy unless a veterinary professional directs you for this exposure.

When should I call the vet?

Call promptly after an accidental ingestion, suspected extra dose, unknown amount or unexpected reaction. Breathing difficulty, collapse, seizures or inability to respond needs emergency veterinary care. Do not wait for those signs before calling.

What should I do after an extra Rimadyl dose?

Call the prescribing veterinarian with the strength, amount and time. Ask what to do before the next scheduled dose, and report any other pain medicine or steroid. Do not assume a dog-labeled medicine is harmless in excess.
