2. Prevention of Influenza: It is also used prophylactically to prevent influenza in individuals who have been exposed to the virus, especially in high-risk populations.
3. Decreased Risk of Complications: By effectively managing influenza, Oseltamivir can help decrease the risk of serious complications such as pneumonia and hospitalization.

Common Side Effects of Oseltamivir Phosphate

3. Fatigue: A general feeling of tiredness may occur, especially in the early days of treatment.

Considerations and Precautions

Before starting treatment with Oseltamivir Phosphate, there are several important considerations:
