Formula Used

Dose (mg) = Weight (kg) × Dosage Factor (2-4 mg/kg)

Where:

  • Weight = Dog's weight in kilograms
  • Dosage Factor = 2 mg/kg for mild pain, 3 mg/kg for moderate pain, 4 mg/kg for severe pain
  • Maximum Daily Dose = 4 mg/kg per dose (8 mg/kg if twice daily)
  • Frequency = Once or twice daily as prescribed by veterinarian

Example Calculation

Real-World Scenario:

A 25 kg Labrador Retriever with moderate arthritis pain being prescribed carprofen chewable tablets (75 mg strength).

Given:

  • Weight = 25 kg
  • Pain Level = Moderate
  • Medication Form = Chewable Tablets
  • Concentration = 75 mg per tablet
  • Frequency = Once daily

Calculation:

Dose (mg) = 25 kg × 3 mg/kg = 75 mg

Number of tablets = 75 mg ÷ 75 mg/tablet = 1 tablet

Result: Administer 1 chewable tablet (75 mg) of carprofen once daily

Common Mistakes & Tips

Carprofen comes in different strengths (25mg, 75mg, 100mg tablets and 50mg/5mL liquid). Using the wrong strength can lead to under or overdosing. Always check the medication label for the exact strength before administering to your dog.

A dog's weight can change over time, affecting the appropriate dosage. Regularly weigh your dog and adjust the medication dosage accordingly. This is especially important for growing puppies or senior dogs who may experience weight fluctuations.

Frequently Asked Questions

Carprofen should not be given with other NSAIDs (like aspirin or ibuprofen) or corticosteroids as this increases the risk of side effects. Always inform your veterinarian about all medications your dog is taking before starting carprofen.

Common side effects may include gastrointestinal upset (vomiting, diarrhea), decreased appetite, lethargy, and changes in behavior. More serious side effects can include kidney or liver problems. Contact your veterinarian if you notice any concerning symptoms after starting carprofen.

Carprofen typically begins to work within 1-2 hours after administration, with maximum effectiveness reached in about 3-4 hours. However, it may take several days of consistent dosing to see the full benefits for chronic conditions like arthritis.
