What is the recommended administration timing for oseltamivir when used for treatment of flu?

Once daily
Twice daily for 5 days
Twice daily for 7 days
Once daily for 10 days

The correct answer is: Twice daily for 5 days

The recommended administration timing for oseltamivir when used for treatment of flu is twice daily for 5 days. This is based on clinical studies which have shown that this dosing regimen is the most effective in reducing the duration of flu symptoms. Option A of once daily may not provide the necessary amount of medication to effectively treat the flu, while options C and D of twice daily for 7 or 10 days may be unnecessarily prolonging the treatment and potentially leading to increased side effects. Therefore, option B is the best choice for treating the flu with oseltamivir.
