How to use
Take it exactly as your doctor prescribed, usually twice a day for treatment. Swallow the capsule whole with water, ideally with food. Complete the full course even if you feel better.
How it works
It blocks an enzyme called neuraminidase that the flu virus needs to escape from infected cells and spread. This slows the spread of the virus in the body.
