Treatment for the Flu: What You Need to Know

Millions of Americans catch the flu each year. It isn’t pleasant, but there are ways you can help yourself feel better. Take good care of yourself this flu season by learning about flu treatment.

How is the flu diagnosed?

The flu is primarily diagnosed by a medical provider based on your symptoms. You can even speak to a medical provider virtually to be diagnosed.


The most common flu symptoms are:

  • Fever

  • Chills

  • Fatigue

  • Headache

  • Body aches

  • Sore throat

  • Congestion

  • Runny nose

  • Cough

  • Shortness of breath


The flu can also be diagnosed through lab tests. PCR flu tests can even identify the type of influenza that’s causing your symptoms.

How long does it take to get the flu (post-exposure)?

When an influenza virus enters your body, it starts to replicate and attack your body’s tissues. In about 1 to 4 days, you will begin to have symptoms of the flu.

When should I see a doctor for flu treatment?

You should see a doctor for your flu symptoms if:

  • You have a fever that improves, but suddenly gets worse

  • Your flu symptoms last longer than 2 weeks

  • You have concentrated pain in one area

  • You develop thick mucus and a persistent cough

  • You are in a high-risk group


People with the highest risk of severe flu complications include:

  • People aged 65 years and older

  • Those with chronic conditions, such as heart disease, diabetes, or asthma

  • People who are pregnant or up to two weeks post-partem

  • Nursing home residents

  • Children younger than 5 years (with the highest risk being for children under 2 years)

See a medical professional right away if you’re at a higher risk of complications. Prescription antiviral treatment for the flu can help protect you, but it needs to be taken quickly.

How is the flu treated?

The most common treatment of flu symptoms is self-care at home. There are also over-the-counter medicines that can ease your flu symptoms. These include painkillers, decongestants and cough syrups.

For high-risk patients, it’s important to get a medical provider involved in your flu treatment. Antiviral medications can reduce the length of illness and lower the chances of complications. Antivirals are most effective when used within the first two days of having symptoms.

Are there any home treatments for the flu?

Most flu cases resolve themselves with rest and home treatment. If you have the flu, self-care is important for a
faster recovery.

Home treatments for the flu:

  • Get plenty of rest to help your body’s immune system do its work. Rest includes getting lots of sleep and reducing your daytime activity levels.

  • Drink lots of water and other fluids. This will help prevent dehydration and also help ease a sore throat. Herbal teas, water, and soups are good options. Avoid caffeinated drinks.

  • Use hot compresses or heat packs to ease sore muscle pain.
