Oseltamivir is an oral antiviral medication used to treat and prevent influenza A and B. It belongs to the neuraminidase inhibitor class and contains Oseltamivir phosphate as its active ingredient. The drug works by blocking the neuraminidase enzyme, which helps stop the virus from spreading in the body. It is most effective when taken within 48 hours of the appearance of symptoms and is typically prescribed for a five-day course. Oseltamivir is available in capsule and liquid forms and should be taken exactly as directed by a healthcare provider.

Oseltamivir is an antiviral medication that inhibits the neuraminidase enzyme, which is found on the surface of influenza viruses. After ingestion, it is converted into its active form, Oseltamivir carboxylate, which blocks neuraminidase activity. This prevents the virus from releasing new viral particles from infected cells, thereby halting its spread within the body. It is effective against both influenza A & B strains and is most beneficial when taken within 48 hours of symptom onset, reducing illness severity & duration.
