Introduction
In general, oseltamivir can be taken for the treatment or prevention of influenza and should be used under the guidance of a physician. When patients exhibit symptoms of influenza virus infection, such as fever, cough, and sore throat, taking oseltamivir can reduce the severity of these symptoms, shorten the duration of illness, and lower the risk of influenza infection.
Oseltamivir is an antiviral medication used to treat influenza, available in capsule and granule formulations. Generally, oseltamivir can be taken for the treatment or prevention of influenza, but must be used under the guidance of a physician. Detailed explanations are as follows:
Oseltamivir is primarily used to relieve symptoms caused by influenza A and B viruses. It inhibits the viral neuraminidase, preventing the virus from being released from infected cells, thereby reducing viral spread within the body. When patients exhibit symptoms of influenza infection, such as fever, cough, and sore throat, taking oseltamivir can reduce the severity of these symptoms and shorten the duration of illness.
Oseltamivir can also be effective during the early stages of potential viral invasion by inhibiting viral replication and spread in the body, thus reducing the risk of influenza infection. If exposed to a confirmed or suspected influenza case, taking oseltamivir within 48 hours after exposure may provide a preventive effect.
It is recommended to strictly follow medical instructions when using oseltamivir, avoiding self-medication or discontinuation of the medication without guidance, to ensure both safety and effectiveness in drug therapy.
