Calculate the appropriate dexamethasone dosage for dogs based on weight, condition, and medication concentration. This tool helps ensure accurate dosing for veterinary treatments.
How to Use This Calculator
- Enter your dog's weight and select the appropriate unit (kg or lbs)
- Input the concentration of your dexamethasone medication
- Select the condition being treated from the dropdown menu
- Choose the administration route (oral or injectable)
- Indicate the severity of the condition
- Click Calculate to see the recommended dosage
Formula Used
Dose (mg) = Weight (kg) × Dosage Factor (mg/kg)
Where:
- Weight (kg) = Dog's weight in kilograms (converted from lbs if necessary)
- Dosage Factor =
- Anti-inflammatory: 0.1-0.3 mg/kg (mild: 0.1, moderate: 0.2, severe: 0.3)
- Immunomodulatory: 0.5-1 mg/kg (mild: 0.5, moderate: 0.75, severe: 1)
- Shock: 4-8 mg/kg (mild: 4, moderate: 6, severe: 8)
- Neurological: 1-2 mg/kg (mild: 1, moderate: 1.5, severe: 2)
- Cancer: 0.5-1 mg/kg (mild: 0.5, moderate: 0.75, severe: 1)
- Volume/Units = Dose (mg) ÷ Concentration (mg/mL or mg/tablet)
Example Calculation
Real-World Scenario:
A 25 lb dog with moderate arthritis pain requiring anti-inflammatory treatment with dexamethasone 0.5 mg tablets.
Given:
- Dog Weight = 25 lbs
- Medication Concentration = 0.5 mg/tablet
- Condition = Anti-inflammatory (Arthritis)
- Severity = Moderate
Calculation:
Convert weight to kg: 25 lbs ÷ 2.2 = 11.36 kg
Dosage factor for moderate anti-inflammatory = 0.2 mg/kg
Dose (mg) = 11.36 kg × 0.2 mg/kg = 2.27 mg
Tablets = 2.27 mg ÷ 0.5 mg/tablet = 4.54 tablets
Result: 4.5 tablets (rounded to nearest half tablet)
