Dosing Recommendations

In adults and adolescents over 13 years of age, the recommended dose of oseltamivir for the treatment of influenza is 75 mg twice daily for 5 days. In younger children, dosing should be based on patient weight, according to the chart below:

Body weight Dosea
≤15 kg 30 mg
16-23 kg 45 mg
24-40 kg 60 mg
> 40 kg 75 mg

a given twice daily for 5 days

As mentioned previously, it is recommended that dosing frequency be reduced in adult patients with moderate renal dysfunction. No studies in pediatric patients with renal dysfunction have been published.5

For influenza prophylaxis in adults and children over 13 years of age, a dose of 75 mg taken once daily for at least 7 days is recommended. The duration of protection lasts as long as therapy is continued.5 Patients and/or parents should be reminded that oseltamivir is not a substitute for the influenza vaccine.
