Most people get better from the flu in about a week.

You should rest, drink plenty of fluids and take an over-the-counter medicine such as acetaminophen (Tylenol). Children under 16 shouldn't take aspirin, because it can be dangerous.

You may still be tired and cough for a week or two after other symptoms go away.¹

For some people, the flu is more serious. They get more serious problems (complications). This is more likely to happen if you are very young, older than 65, or have another medical problem, such as heart disease.²

Flu complications include:^{1 3}

• Trouble breathing
• Pneumonia, caused by bacteria or a virus
• Ear infection
• Sinus infection
• Worsening of an existing problem such as diabetes or asthma.

If you get a complication caused by bacteria, your doctor will prescribe antibiotics. Antibiotics won't affect the flu. If you get very sick, you may need to be treated in the hospital.²

Taking a flu vaccine can help prevent the flu. To read more, see Flu vaccines.
