Dexamethasone Dosage Calculator for Dogs
Calculate the proper dosage of dexamethasone for dogs based on weight, condition, and treatment duration. This tool helps veterinary professionals determine accurate corticosteroid dosing for various conditions.
How to Use This Calculator
- Enter the dog's weight in kilograms (kg)
- Select the condition being treated from the dropdown menu
- Adjust the dosage strength if needed (default values are provided based on condition)
- Select the concentration of dexamethasone solution available
- Enter the treatment duration in days
- Choose the administration frequency (once or twice daily)
- Optionally, select to include a tapering schedule for longer treatments
Formula Used
Dose (mg) = Weight (kg) × Dosage Strength (mg/kg)
Volume (mL) = Dose (mg) ÷ Concentration (mg/mL)
Total Treatment (mg) = Dose (mg) × Frequency × Duration (days)
Where:
- Weight = Dog's body weight in kilograms
- Dosage Strength = Recommended milligrams per kilogram based on condition
- Concentration = Dexamethasone solution concentration in milligrams per milliliter
- Volume = Final calculated volume to administer per dose
- Frequency = Number of administrations per day
- Duration = Length of treatment in days
Example Calculation
Real-World Scenario:
A veterinarian needs to treat a 15 kg dog with inflammatory arthritis using dexamethasone 2 mg/mL solution for 7 days.
Given:
- Dog Weight = 15 kg
- Condition = Inflammatory
- Dosage Strength = 0.2 mg/kg
- Concentration = 2 mg/mL
- Treatment Duration = 7 days
- Frequency = Once daily
Calculation:
Dose (mg) = 15 kg × 0.2 mg/kg = 3 mg
Volume (mL) = 3 mg ÷ 2 mg/mL = 1.5 mL
Total Treatment (mg) = 3 mg × 1 × 7 days = 21 mg
Result: Administer 1.5 mL of dexamethasone 2 mg/mL solution once daily for 7 days. Total treatment amount is 21 mg.
