Introduction

Oseltamivir is commonly available in granules, capsules, and suspensions. It is an antiviral medication that demonstrates good efficacy in the prevention and treatment of influenza A and B virus infections. However, it may be ineffective or cause adverse reactions when used in cases of non-influenza viral infections, after influenza symptoms have already subsided, or in populations with contraindications. If any abnormalities occur, prompt medical attention is recommended.

Oseltamivir is commonly available in granules, capsules, and suspensions. It is an antiviral medication that demonstrates good efficacy in the prevention and treatment of influenza A and B virus infections. However, it may be ineffective or cause adverse reactions when used for non-influenza viral infections, after influenza symptoms have already improved, or among individuals with contraindications. If any abnormalities occur, timely medical attention is recommended. Detailed explanations are as follows:

Oseltamivir can effectively prevent and treat influenza A and B virus infections. Patients who have already contracted the influenza virus can take oseltamivir as directed by a physician to inhibit viral replication and spread within the body, thereby alleviating symptoms and shortening the duration of illness. Oseltamivir may also be used for treatment in elderly individuals, children, or patients with chronic diseases who have weakened immune systems and are more susceptible to influenza infection and severe symptoms, thus reducing the risk of infection.

Oseltamivir is ineffective against pathogens other than influenza A and B viruses. If a patient's respiratory infection is caused by other pathogens, oseltamivir may not be effective. Additionally, if influenza symptoms have already resolved, taking the medication will not provide additional therapeutic benefits. Furthermore, oseltamivir may be ineffective and even cause serious harm in certain populations, including patients allergic to its components, those with severe liver or kidney dysfunction, and pregnant or breastfeeding women.

It is recommended to maintain a healthy lifestyle with regular作息 (作息 should be translated as "routine" or "daily habits"), sufficient sleep, improved dietary habits, and proper physical conditioning to promote overall health.
