The flu is serious.

The flu hits hard and fast, and can leave you with debilitating symptoms that last for more than a week. You can miss out on work, hobbies, and time with family and friends. And it's not just you. The CDC estimates that each year, up to 49 million people will be affected by the flu.

If left untreated, the flu virus can lead to serious complications including pneumonia, dehydration, hospitalization and, in some cases, even death. The sooner you talk to your doctor about XOFLUZA, a prescription flu treatment, the better chance you have of fighting the flu.

*On average, patients felt better in 2.3 days versus 3.3 days with placebo.

Fever, aches, and chills are common flu symptoms.

You don't have to have all of these symptoms to have the flu. If you're experiencing any symptoms, like the ones listed below, don’t wait for things to get worse—see your doctor as soon as possible.
