What is Oseltamivir?

Generally, oseltamivir is available in forms such as suspensions and capsules. Oseltamivir is an antiviral medication. Patients should select a suitable formulation and treatment regimen under a doctor's guidance and strictly follow medical instructions for administration. The analysis is as follows:

Oseltamivir primarily exerts its antiviral effects by inhibiting the neuraminidase activity of influenza A and B viruses. After infecting human cells, influenza viruses rely on neuraminidase to detach from the surface of infected cells and subsequently infect other healthy cells. By inhibiting this enzyme, oseltamivir prevents the release and further spread of the virus, thereby inhibiting viral replication and dissemination within the body.

Oseltamivir is primarily used for the treatment of influenza A and B in adults and children aged one year and older. Prompt administration of oseltamivir after confirmed influenza infection can effectively alleviate flu symptoms, shorten the duration of illness, and reduce the risk of severe complications such as pneumonia and respiratory failure.

In specific situations, oseltamivir can also be used to prevent influenza. For example, during peak influenza season, individuals who have not received the influenza vaccine but have had contact with confirmed cases may take oseltamivir as directed by a physician to help reduce the likelihood of infection.

Following medication, some patients may experience gastrointestinal discomfort, such as nausea, vomiting, and abdominal pain. At this time, timely rest is necessary, and consumption of spicy or irritating foods should be avoided to prevent worsening of symptoms.
