How can I treat the flu at home, and when should I go to urgent care?

One minute you’re fine. The next, you’re buried under blankets, sweating through a fever, and every part of your body aches, even your toes. We’re so sorry, but now you have the flu. Core Medicine of Idaho Family Practice and Urgent Care helps families throughout Canyon County navigate flu season every year. Fortunately, you can usually manage the virus on your own. Let’s first walk through what works for home flu treatments—and when it’s time to make an appointment in our urgent care clinic.

What Home Remedies Help Most When You Have the Flu?

In most healthy children and adults, this condition lasts between 5 to 7 days, with symptoms often peaking around day 2 or 3. While fatigue and a lingering cough may stick around for a couple of weeks, the worst of the illness usually passes within the first week if managed properly.

You don’t need to rush in to see us if you or your child gets the flu. With rest and basic care, many people recover fully with home flu treatment. The following steps not only help reduce discomfort but also support your immune system’s work in clearing the virus efficiently. Here's what works best.

Get Plenty of Rest

Don’t try to push through a fever or return to work or school too soon—give yourself permission to fully slow down. Stay in bed or rest on the couch, and avoid unnecessary movement until your fever breaks and energy returns. Keep track of your temperature, energy levels, and any new symptoms so you can spot signs of complications early.

Stay Hydrated 

Fever, sweating, and congestion can lead to significant fluid loss. Sip water throughout the day, even if you're not thirsty. If water feels too bland, try adding lemon or a splash of juice to encourage more consistent intake. Electrolyte drinks, warm broths, and herbal teas are also excellent choices for hydration.

Use Over-the-Counter Medications 

Medications like acetaminophen or ibuprofen can lower your fever and reduce body aches. Decongestants may ease sinus pressure, and cough suppressants might provide relief at night. Always follow the dosing instructions and check with a pharmacist if you take other medications or have chronic conditions.

Soothe Your Throat and Cough 

Saltwater gargles, honey in tea—for adults and children over age 2—throat lozenges, and menthol rubs all work to ease throat pain and irritation. A humidifier is also helpful for keeping your nasal passages moist and reducing nighttime coughing.

Eat Light, Nutritious Meals 

Even if your appetite is low, try to eat small amounts of food to maintain energy. Warm soups, bananas, toast, applesauce, and rice are gentle on the stomach. If you’re feeling nauseated, eat slowly and in small portions, focusing on hydration first.

How Can You Prevent the Flu From Spreading in Your Household?

Follow the same home flu treatments above and reduce the spread of the virus by: 

• Isolating the sick person. Keep them in a separate room and minimize contact if possible.
• Washing hands often. Soap and water work best—especially after coughing, sneezing, or touching shared surfaces.
• Disinfecting frequently touched items. This includes doorknobs, phones, remotes, and bathroom surfaces.
• Not sharing towels, drinks, or utensils. The flu virus can linger on surfaces for hours.
• Wearing a mask indoors if caring for someone ill. Especially important for high-risk caregivers.

Are You at Higher Risk for Flu Complications?

Even if symptoms seem mild, people in high-risk groups should consider reaching out to our Idaho urgent care clinic early in their illness. This includes:

• Children under 5, and especially younger than 2
• Adults over 65
• People with asthma, diabetes, heart disease, or weakened immune systems
• Pregnant or postpartum individuals
• Residents of long-term care facilities

One of our experienced providers may prescribe antiviral medication like oseltamivir, which can shorten the illness if taken within 48 hours of symptom onset.

If Home Flu Treatment Doesn’t Seem to Help, When Should You Call Our Idaho Urgent Care Providers?

Don’t hesitate to make an appointment if you have:

• Shortness of breath or chest pain.
• A fever lasting more than 4 days.
• Signs of severe dehydration, such as dry mouth, dizziness, and reduced urination.
• Confusion or sudden dizziness.
• Worsening cough with green/yellow mucus. 
• Stomach flu development.

Seek immediate care for a child with symptoms such as:

• Labored breathing
• Bluish lips
• Difficulty waking
• Signs of dehydration, especially if your toddler hasn’t had a wet diaper for more than 8 hours

Does the Flu Shot Still Make a Difference, Even If You’ve Already Been Sick?

Absolutely! Vaccines teach your body to defend itself and reduce the spread of disease. Getting a flu shot each year is the best way to reduce your risk of serious illness. 

The flu consists of two main strains: Influenza A and Influenza B. Influenza A typically appears early in the fall and winter and accounts for more than two-thirds of all flu cases. Influenza B typically appears later in the season around February or March.

So, depending on when you and your family members get immunized, it might not prevent you from catching the flu entirely, but it will help: 

• Reduce your chance of hospitalization.
• Make symptoms milder if you do get sick.
• Protect vulnerable loved ones around you.

Flu vaccines are available at Core Medicine of Idaho for patients of all ages—walk in or schedule an appointment today.
