How long should oseltamivir be taken for prevention after potential flu exposure?

Oseltamivir, an antiviral medication, is recommended for post-exposure prophylaxis against influenza when an individual has been in close contact with a confirmed case of the virus. The standard duration for taking oseltamivir in this context is typically 10 days. This duration allows for adequate suppression of the virus and helps prevent the onset of influenza symptoms in individuals who may have been exposed.

In situations where prevention is necessary, the 10-day regimen ensures that the drug remains effective throughout the potential incubation period of the virus, thus minimizing the risk of developing influenza. The other suggested durations are not aligned with the established guidelines for prophylactic treatment, making the 10-day course the most appropriate and effective duration for oseltamivir after potential flu exposure.
