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

Your doctor or HCP may recommend taking over-the-counter medications to reduce severity of symptoms while the antiviral action of Tamiflu takes effect on the flu virus.
As with any medication, be sure to discuss with your doctor any over-the-counter or prescription medicines you are currently taking before beginning Tamiflu therapy.
