Oseltamivir, commonly known as Tamiflu, is a potent antiviral medication used to treat influenza infections. By inhibiting the neuraminidase enzyme, it prevents the release of newly formed viral particles from infected cells, effectively curbing viral replication. Administered orally in capsule or liquid form, Oseltamivir 75mg is most effective when initiated within 48 hours of symptom onset, reducing the duration and severity of flu symptoms. While generally well-tolerated, potential side effects include nausea and vomiting. However, overuse can contribute to antiviral resistance, underscoring the importance of judicious usage. Despite its efficacy in treating influenza, Oseltamivir does not substitute for vaccination, the primary preventive measure against flu infections. Consulting healthcare professionals for proper dosage and guidance is essential to ensure optimal outcomes and minimize risks. Oseltamivir plays a crucial role in managing influenza, empowering individuals to combat the seasonal flu and mitigate its impact on health and well-being.
