How to Treat the Flu

Have you caught the flu? Knowing how to care for yourself can help you feel better sooner and protect others from getting sick. At Banner Health, we’re here to guide you through flu treatment, medication safety and what to expect during recovery.

At-home flu treatment: What you can do

Most cases of the flu can be managed at home with simple steps:

• Get plenty of rest – Sleep helps your immune system fight the virus
• Stay hydrated – Drink water, herbal teas and clear broths to replace fluids lost through fever or sweating
• Manage fever and pain – Use over-the-counter (OTC) medicines like acetaminophen (Tylenol) or ibuprofen (Advil or Motrin)
• Avoid aspirin – Aspirin use during flu illness has been linked to Reye’s syndrome, a rare but serious condition
• Ease sore throat and congestion – Gargle warm salt water or inhale steam from a bowl of hot water or shower
• Use saline nasal sprays or rinses – These can help with nasal stuffiness
• Stay home – Avoid contact with others until you are fever-free (without medication) for at least 24 hours
• Watch for serious symptoms – Contact your provider if symptoms worsen or you show signs of dehydration

Choosing over-the-counter flu medications

OTC cold and flu medications can ease your symptoms, but they must be used safely. Always follow the instructions on the label and talk with your provider or pharmacist if you’re unsure.

Common types of OTC medications include:

• Pain relievers/fever reducers – Acetaminophen or ibuprofen
• Decongestants – Help clear nasal passages
• Antihistamines – May reduce sneezing and runny nose
• Cough medicines – Cough suppressants and lozenges can help soothe your throat

If you have high blood pressure

Some flu medications can raise blood pressure or interfere with your usual medications. If you have hypertension:

• Talk to your provider – They can help you choose safe treatment options
• Look for “hypertension-friendly” labels on OTC products
• Watch your sodium – Some liquids or broths may contain high sodium levels
• Monitor your blood pressure – Let your provider know if your readings change

Antiviral medications for the flu

While many people recover with home care alone, antiviral medications may be prescribed in certain situations—especially if you’re in a high-risk group or have severe symptoms.

Antiviral flu drugs include:

• Oseltamivir (Tamiflu)
• Zanamivir (Relenza)
• Peramivir (Rapivab)
• Baloxavir (Xofluza)

To work effectively, antiviral medications must be started within 48 hours of the first symptoms. Your provider will let you know if one is right for you.

How long does the flu last?

Mild flu cases usually last 7 to 14 days. Fatigue and a cough may linger for a few weeks even after your main symptoms improve.

The flu is contagious before symptoms appear (up to 24 hours in advance) and for about a week after symptoms begin. Wait until you’ve been fever-free for at least 24 hours (without medication) before returning to work, school or other public settings.

Can I still get a flu shot?

Yes. Even if you’ve had the flu, you should still consider getting a flu shot once you’ve recovered.

Each year, several strains of the flu circulate. The vaccine protects against the most common ones and can reduce the severity and length of illness if you get the flu again.
