When to take your child to the ER for a fever

Mild fever is generally easy to treat at home with rest, fluids and over-the-counter medications. However, sometimes fever is an indicator of a more serious infection. See below to help determine when to take your child to the doctor for a fever.

Typically, it is best to call your doctor first before heading to the ER. However, if your pediatrician is unavailable, here are some general guidelines for when to go to the ER. 

Newborns and infants younger than 3 months old

If your baby is less than 3 months old, visit the pediatric ER if his or her temperature is above 100.4 degrees. You should also seek emergency care if your baby’s fever is accompanied by these symptoms: 

• Difficulty waking up to be fed
• Difficulty breathing
• Rash
• Vomiting
• Inconsolable or non-stop crying

Babies and toddlers 3 months to 3 years

For babies and toddlers between the age of 3 months and 3 years, visit the pediatric ER if the child’s temperature is above 102.2 degrees, or if the child is displaying these symptoms: 

• Difficulty waking up
• Not urinating
• Unable to keep fluids down
• Inconsolable
• Not up to date on immunizations
• Difficulty breathing
• Rash

Children age 3 and older

If your child is 3 or older, visit the pediatric ER if the child’s temperature is over 102 degrees for two or more days. You should also seek emergency care if the fever is accompanied by any of these symptoms:
