Tamiflu for Adults
Tamiflu is an FDA-approved prescription flu medicine that attacks the flu at its source. Tamiflu doesn’t just treat the symptoms of flu that make you feel bad. Tamiflu fights the flu virus itself. This may help limit the flu’s ability to spread in your body.
In fact, Tamiflu has been clinically proven to help you get better 30% (1.3 days) faster when taken within 48 hours of first symptoms. So the sooner you start Tamiflu, the sooner you may start feeling better, faster.14
