Oseltamivir is an antiviral medication used for the treatment and prevention of influenza caused by influenza A and B viruses. It is most effective when taken within the first 48 hours of symptom onset.

Oseltamivir works by inhibiting neuraminidase, an enzyme essential for the replication and spread of the influenza virus in the body. By blocking this enzyme, the medication reduces the severity of symptoms, the duration of the illness, and the risk of complications such as pneumonia.

It is indicated for both the treatment of influenza in adults and children (including infants over 2 weeks old) and for the prevention of influenza in individuals exposed to the virus (e.g., through contact with an infected person).

Common side effects include nausea, vomiting, headache, and abdominal discomfort. These reactions are usually mild and temporary. In rare cases, severe allergic reactions or neuropsychiatric disturbances, such as confusion, hallucinations, or abnormal behavior, may occur, particularly in children and adolescents.

Patients should strictly follow their doctor’s instructions regarding dosage and duration of treatment. Oseltamivir does not replace influenza vaccination, which remains the most effective method of preventing the flu. It is important to consult a doctor before use, especially for pregnant women, individuals with kidney conditions, or those taking other medications.
