You Think You Have the Flu. Now What?

In most cases, the best way to treat it is to:

  • Rest at home.
  • Drink plenty of fluids.
  • Avoid contact with other people.

If you're very sick or you have other medical conditions, you might need treatment with prescription medications called antiviral drugs.

These medicines -- oseltamivir (Tamiflu), peramivir (Rapivab), or zanamivir (Relenza) -- work best when you take them within 48 hours after your symptoms start. They can shorten the length of your illness by a day if you take them within this early window. They might help even after 2 days, if you have a bad case.

Your doctor may want you to take antiviral drugs if you have a high risk of complications from the flu.

When Is Flu Season?

Seasonal flu follows a fairly predictable pattern, starting in the fall and ending in the spring. A sign that it’s started is the sudden rise in the number of school-aged children sick at home with a flu-like illness. This first outbreak is soon followed by an uptick in other age groups, especially adults.
