This calculator determines the Oseltamivir dose for treating influenza, using a concentration of Oseltamivir 6 mg/mL, based on the patient’s weight and age group:
Dose in mL and mg (based on Oseltamivir):
Pediatric ≥ 1 year:
Adults: 12.5 mL (75 mg) PO BID for 5 days
Where:
Administer as prescribed for influenza. ⚠️ Always consult a healthcare provider.
Enter the patient’s weight in kilograms or pounds, select the unit, choose the age group, and click "Calculate." The calculator provides the dose in mL and mg (Oseltamivir) based on the selected age group and weight range.
Example: Weight 20 kg, Pediatric ≥ 1 year:
Pediatric ≥ 1 year (>15 to 23 kg): 7.5 mL (45 mg) PO BID for 5 days Adult dose: 12.5 mL (75 mg) PO BID for 5 days Calculations must be re-checked and should not be used alone...
Consult a healthcare provider before administering.
Oseltamivir (Tamiflu) is used to treat and prevent influenza A and B infections.
Pediatric ≥ 1 year: 30 mg, 45 mg, 60 mg, or 75 mg PO BID for 5 days, based on weight (≤15 kg, >15 to 23 kg, >23 to 40 kg, or >40 kg). Adults: 75 mg PO BID for 5 days.
Consult a doctor, as Oseltamivir is not typically recommended for children under 1 year without medical supervision.
Enter the weight in pounds, and the calculator will automatically convert it to kilograms for calculation (1 lb = 0.4536 kg approximately).
The maximum dose for pediatric patients (≥1 year) is 12.5 mL (75 mg) PO BID for 5 days for weights >40 kg.
