How to Spot Flu Symptoms in Kids (And What to Do Next)
Understanding Flu Symptoms in Kids
Flu (influenza) is a contagious respiratory virus that spreads quickly—especially among children. Because kids often spend time in close quarters at school or daycare, they’re more likely to catch and pass along the flu.
Flu symptoms in kids can include:
- Fever and chills
- Headache and body aches
- Sore throat and cough
- Runny or stuffy nose
- Fatigue and weakness
- Vomiting, diarrhea, or abdominal pain
While many cold viruses have overlapping symptoms, flu tends to come on quickly and make children feel more intensely unwell.
Supportive Care Measures for Flu Symptoms in Kids
In most cases, flu symptoms in kids resolve with supportive care and rest. The goal is to keep your child hydrated, comfortable, and monitored for any signs of complications.

- Fluids: Encourage small sips throughout the day—water, diluted juice, or pediatric electrolyte drinks work well.
- Congestion relief: Use saline sprays, nasal suction for babies, and warm showers or humidifiers to ease stuffy noses.
- Sore throat remedies: Offer warm chamomile tea (with honey for kids over age 1), warm broths, or soothing popsicles.
- Fever relief: Use acetaminophen (Tylenol) or ibuprofen (Motrin) as directed by your pediatrician. Never give aspirin to children.
- Rest: Let your child rest and recover fully before returning to school or other activities.
Remember—over-the-counter cold medications are not recommended for young children without specific pediatric guidance.
Antiviral Medications for Flu Symptoms in Kids
For some children, a flu diagnosis may lead to a discussion about antiviral treatment. Antiviral medications can shorten flu symptoms by about 24–36 hours and reduce their severity—but only if given within 48 hours of symptom onset.
Tamiflu (Oseltamivir)
- Dosing: Twice daily for 5 days
- Age: Approved for children as young as 2 weeks
- Form: Available in liquid or capsule
- Side effects: Nausea, vomiting, abdominal pain, and in rare cases, confusion or agitation
Xofluza (Baloxavir Marboxil)
- Dosing: Single-dose pill
- Age: Approved for children 5 years and older
- Form: Tablet only (must be swallowed whole)
- Side effects: Typically mild but can include vomiting or diarrhea
Talk with your pediatrician about which option is appropriate for your child.
Who Should Consider Antiviral Medication?
Not every child with the flu needs antivirals. Healthy children typically recover well without medication. However, the CDC recommends antivirals for children at higher risk of complications, including:

- Children under 2 years old
- Children with chronic conditions like asthma, diabetes, heart disease, or immunocompromising illnesses
- Those with metabolic, kidney, or liver disorders
- Pregnant patients or adults 65+ in the household
If your child tests positive for the flu, your provider will consider age, medical history, and timing to decide if antivirals are appropriate.
Prevention Is Key
While treating flu symptoms is important, the best approach is prevention:
- Get the flu shot each year (recommended for everyone 6 months and older)
- Practice good hand hygiene
- Avoid close contact with those who are sick
- Stay home when sick to avoid spreading germs
According to the AAP, annual flu vaccination significantly reduces the risk of severe flu complications in children
The Bottom Line
Flu symptoms in kids can be tough—but most children recover with rest, fluids, and supportive care. If symptoms are severe or your child is at higher risk, antiviral medication may be appropriate. Your pediatrician is always your best resource for guidance.
By combining thoughtful care with flu prevention strategies, you can help protect your child—and your household—through every flu season.
