Introduction
Oseltamivir is generally taken for 3 to 7 days. For individuals who are relatively healthy with mild symptoms, the treatment course may last 3 to 5 days. However, for those with chronic underlying conditions, the duration of treatment may be 5 to 7 days. It is recommended to maintain good dietary habits in daily life. Additionally, measures such as frequent handwashing and wearing masks are advised to prevent illness.
Generally, oseltamivir is available in tablet, capsule, and suspension forms. For relatively healthy individuals with mild symptoms, the treatment course may last 3-5 days. However, for individuals with underlying chronic conditions, the treatment duration may extend to 5-7 days. Detailed explanations are as follows:
Oseltamivir is an antiviral medication that works by inhibiting neuraminidase, thereby preventing the release of mature influenza virus from host cells and subsequently suppressing viral spread within the body. In relatively healthy individuals with strong immune systems, the body's ability to eliminate the virus is stronger, leading to faster recovery. For those with mild symptoms, such as low-grade fever, cough, and runny nose, the treatment duration is generally 3-5 days.
However, in children with underlying chronic diseases, the body's resistance is weaker, resulting in more severe illness and a prolonged recovery period after viral infection. Symptoms such as high fever, severe cough, and difficulty breathing may further weaken the body, necessitating a treatment duration of 5-7 days.
In daily life, it is recommended to maintain good dietary habits. Additionally, preventive measures such as frequent handwashing and wearing masks are advised to prevent illness.
