How to Calculate Salbutamol 2 mg/5 mL Dose

This calculator determines the Salbutamol dose for treating asthma or bronchospasm, using a concentration of Salbutamol 2 mg/5 mL (0.4 mg/mL), based on the patient’s weight for children 2–6 years, age for children 6–12 years, and a fixed range for adults:

Dose in mL and mg (based on Salbutamol):

Where:

• Weight: Enter the patient’s weight in kilograms (kg) or pounds (lb) and select the unit from the dropdown (automatically converted to kg). Weight must be at least 10 kg for children ≥ 2 years.
• Concentration: Salbutamol 2 mg/5 mL (0.4 mg/mL).

Administer as prescribed for asthma or bronchospasm. ⚠️ Always consult a healthcare provider.

Using the Salbutamol 2 mg/5 mL Dosage Calculator

Enter the patient’s weight in kilograms or pounds, select the unit, and click "Calculate." The calculator provides the dose in mL and mg (Salbutamol) for children 2–6 years (weight-based), children 6–12 years (age-based), and adults, ensuring the minimum dose (if applicable) is less than or equal to the maximum dose for adults. If the weight is less than 10 kg, an error message will appear.

Example: Weight 10 kg:

2–6 years (weight based dosing):
2.5 mL (1 mg) po TID to QID

6–12 years (age based dosing):
5 mL (2 mg) po TID to QID

Adults:
Usual dose is 5 mL (2 mg) to 10 mL (4 mg) po TID to QID

Calculations must be re-checked and should not be used alone...
            

Consult a healthcare provider before administering.

3. Can this be used for children under 2 years?

Consult a doctor, as Salbutamol is not typically recommended for children under 2 years without medical supervision.

4. What if weight is in pounds?

Enter the weight in pounds, and the calculator will automatically convert it to kilograms for calculation (1 lb = 0.4536 kg approximately). Weight must be at least 10 kg (approximately 22 lbs) for children ≥ 2 years.

5. What’s the maximum dose per administration?

The maximum dose per administration is 2 mg for children 2–12 years and not specified beyond the usual range for adults (typically managed by clinical judgment).
