Carprofen is a widely prescribed non-steroidal anti-inflammatory drug (NSAID) used by veterinarians to manage pain, reduce inflammation, and alleviate fever in dogs. It is particularly effective in treating osteoarthritis (OA) and other inflammatory conditions. The medication is available under various brand names, with Rimadyl being the most recognized FDA-approved option. Veterinarians may also prescribe Rimadyl to manage post-operative pain. Other brand names for carprofen include Carprieve, Novox, Carpaquin, Quellin, Vetprofen, and Carprovet.
In specific situations, your veterinarian might recommend a compounded form of carprofen. This is typically done when a commercially available FDA-approved drug doesn’t meet your pet’s unique health needs, such as difficulties with pill-taking, unavailable dosage strengths, or allergies to specific ingredients. It’s important to note that compounded medications are not FDA-approved and are prepared on an individual basis by a licensed veterinarian or pharmacist.
How Carprofen Works
Carprofen functions as an NSAID by targeting and reducing inflammation, which in turn alleviates pain. NSAIDs generally work by inhibiting the production of natural chemicals that trigger inflammation through the body’s COX pathways. Some of these pathways are also crucial for maintaining normal bodily functions like digestion, kidney health, and blood clotting. Carprofen is particularly effective in dogs because it significantly reduces the chemicals responsible for inflammation while minimizing the impact on other bodily functions. This selective action leads to fewer side effects compared to some other NSAIDs.
Administration and Dosage
Always follow your veterinarian’s instructions and the directions on the drug label for administering carprofen. The prescribed dosage and treatment plan will be tailored to your dog’s weight and the specific cause of their pain. Many dogs readily accept Rimadyl chewable tablets as a treat. If your dog is reluctant, you can hide the tablet in a small amount of palatable food. While carprofen can be given with or without food, administering it with food may help reduce the likelihood of stomach upset.
Continue administering Rimadyl for the duration recommended by your veterinarian, as many dogs, especially those with OA, require long-term treatment. If your dog continues to show signs of pain, such as reluctance to play, climb stairs, or jump, consult your veterinarian, as additional pain management may be needed.
Missed Doses
If you miss a dose, contact your veterinarian for guidance. Typically, you might be advised to give the missed dose as soon as you remember, or if the next dose is imminent, to skip the missed dose and resume your regular schedule. Never administer double doses.
Potential Side Effects and Safety
Although carprofen is generally well-tolerated, serious side effects can occur. Contact your veterinarian immediately if you observe any of the following:
- Vomiting or diarrhea
- Loss of appetite
- Lethargy or decreased activity
- Increased thirst or urination
- Yellowing of the skin, gums, or whites of the eyes (jaundice)
- Behavioral changes
- Skin rash or itching
- Seizures
Serious reactions can manifest without warning. However, most dogs recover if the medication is discontinued promptly and appropriate emergency veterinary care is provided.
Human Safety
Carprofen is a prescription veterinary medication and is not intended for human use. Humans should never take medication prescribed for pets, and pets should not be given human medications. If accidental ingestion occurs, contact your physician or the national Poison Control Center at 800-222-1222.
Monitoring Your Pet
Your veterinarian will likely recommend routine monitoring, typically including blood work (complete blood cell count and chemistry panel), while your pet is on carprofen. This monitoring helps assess kidney and liver function and can vary based on your pet’s individual needs, duration of treatment, and concurrent medications.
When to Contact Your Veterinarian
Always reach out to your veterinarian if you notice any side effects, if your pet’s condition worsens or doesn’t improve, if you suspect an overdose, or if you have any questions or concerns about the medication.
Overdose Concerns
Rimadyl chewable tablets are designed to be palatable for dogs, which increases the risk of overdose if they gain access to the medication. Overdosing can lead to severe side effects, often requiring emergency treatment. If an overdose is suspected, contact your veterinarian or an animal poison control center immediately. You can also contact the manufacturer of Rimadyl at (888) 963-8471.
Storage Instructions
Always confirm storage requirements on the prescription label. Store Rimadyl tablets at temperatures between 59–86°F (15–30°C). Because of their appealing taste to pets, it is crucial to store carprofen securely out of reach of children and animals to prevent accidental ingestion and potential overdose.
Frequently Asked Questions
How long does Rimadyl take to work?
Rimadyl typically reaches peak blood levels within one to three hours, but visible improvement in your dog’s pain or inflammation may take a few days. For chronic conditions like osteoarthritis, consistent, long-term treatment is often necessary. Your veterinarian will determine the appropriate treatment duration.
Is Rimadyl harmful to dogs?
While generally well-tolerated, serious side effects can occur rarely and without warning. Contact your veterinarian immediately if you observe any side effects. Most dogs recover with prompt discontinuation of the medication and necessary veterinary care. Discuss with your veterinarian if Rimadyl is the right choice for your dog.
Is carprofen the same as ibuprofen?
Both carprofen and ibuprofen are NSAIDs, but carprofen is specifically formulated for dogs, while ibuprofen is for human use. Ibuprofen is considered toxic to dogs due to their inability to metabolize it effectively, and even small doses can cause severe, life-threatening effects. Always use veterinarian-prescribed pain medications for your pet.
Does carprofen cause drowsiness in dogs?
Carprofen itself does not cause sedation or grogginess. However, as it effectively reduces pain and discomfort, you may observe your dog resting and sleeping more comfortably.
