Which of the following statements about Oseltamivir is true?

Oseltamivir is an antiviral medication primarily used to treat and prevent influenza virus infections. The statement that it can be taken with or without food is correct, as food does not significantly affect its absorption or efficacy. This flexibility in administration makes it convenient for patients, as they can take the medication in a manner that fits their lifestyle without compromising its effectiveness.

In contrast to the other statements, Oseltamivir is not a broad-spectrum antiviral medication; it is specifically targeted against the influenza virus. While it is an important antiviral for treating flu, it does not have efficacy against bacterial infections, which is a crucial distinction since bacterial infections require different forms of treatment such as antibiotics. Additionally, Oseltamivir is classified as a prescription medication, meaning it must be prescribed by a healthcare provider, ensuring appropriate use and monitoring.
