Answer

Answer

Oseltamivir treatment varies by weight, as follows:

  • ≤15 kg: oseltamivir 30 mg PO once daily for 7 days
  • >15 to 23 kg: oseltamivir 45 mg PO once daily for 7 days
  • >23 to 40 kg: oseltamivir 60 mg PO once daily for 7 days
  • >40 kg: oseltamivir 75 mg PO once daily for 7 days

Zanamivir prophylaxis (aged ≥5 y) consists of 10 mg (two 5-mg inhalations) inhaled PO once daily for 7 days.
