From the Guidelines
The recommended dose of Tamiflu (Oseltamivir) 6mg/mL for a 7-year-old child weighing 33.68kg is 45mg twice daily, which can be administered as 7.5mL of the 6mg/mL oral suspension 1.
Key Considerations
- The dose is based on the child's weight, with a recommended dose of 45mg twice daily for children weighing >15 kg and up to 23 kg, and 60mg twice daily for children weighing >23 kg and up to 40 kg 1.
- The treatment duration is 5 days, with the first dose initiated within 48 hours of symptom onset for optimal efficacy 1.
- Oseltamivir is available as a powder for oral suspension that is reconstituted to provide a final concentration of 6 mg/mL, and the dose can be administered with or without food, although administration with meals may improve gastrointestinal tolerability 1.
- It is essential to note that the dose may need to be adjusted in patients with renal insufficiency, and the treatment should be initiated as soon as possible after symptom onset for optimal efficacy 1.
