• B. 75 mg daily for 7 days with food
• C. 75 mg BID for 5 days with food
• D. 1 mg / 10 mL

Answer: (B)

The correct dosage for the prevention of influenza with Tamiflu (oseltamivir) is 75 mg taken once daily for 7 days. This regimen is designed to effectively reduce the risk of developing influenza after exposure to the virus, such as in a household setting where someone has been diagnosed with the flu. Taking the medication with food can help improve tolerance and reduce potential gastrointestinal side effects, which may occur when the medication is taken on an empty stomach. This guideline emphasizes the importance of adhering to prescribed dosages and routes of administration to maximize the medication's effectiveness in preventing influenza. The other dosing regimens listed do not align with the established preventive guidelines for Tamiflu. The two options that suggest multiple doses per day or longer durations exceed the recommended preventive dosing protocol, while the last choice pertains to a concentration of the medication that is not relevant to prevention in this context.
