When to go to the emergency room for a fever

Fevers might not feel good, but they are one of your body’s natural ways of fighting off infection. But despite the important role they play in keeping your body healthy, sometimes fevers can be dangerous. So, how do you know when a fever warrants a visit to the emergency room? We’ll help you understand the difference between a fever that’s working in your favor and one that may require care from emergency medicine specialists.

What is a fever?

According to the National Institutes of Health, the normal temperature of the human body is 98.6 degrees Fahrenheit (F). A fever is simply a temporary rise in your body temperature. Although it can leave you feeling out of sorts, it isn’t usually a cause for concern. 

For children of toddler age and beyond, as well as for adults, a temperature of above 100.4 degrees is considered a fever. Not all fevers need to be treated and most will go away on their own within a few days.

Treating a fever at home

Since fevers can quickly cause dehydration, especially in children, the best way to care for a fever at home is to drink water, sports drinks or other oral electrolyte supplements. It’s also important to get plenty of rest and to eat easily digestible foods such as bananas, rice and toast.

Most fevers can also be lowered at home with a variety of over-the-counter medicines, including acetaminophen (Tylenol) and ibuprofen (Advil). According to the National Institutes of Health, these medications, taken in proper dosage, are safe for children. 

Of course, if you’re concerned, it’s always a good idea to visit your primary care provider at an in-person or telehealth visit. You can also see an urgent care near you during nights, weekends or if appointments are not available with your provider. 

When adults should go to the emergency room for a fever

Seek medical attention right away if you’re an adult with a fever greater than 104 degrees F. High fevers are especially dangerous because they can rapidly dehydrate you and damage your organs. If left untreated, it can lead to brain damage. 

You should also seek treatment if your fever is accompanied by any of these symptoms:

• Abdominal pain
• Confusion
• Difficulty breathing
• Foul-smelling vaginal discharge
• Loss of consciousness
• Painful urination
• Rash
• Seizure
• Severe body pain, swelling or inflammation
• Severe headache or sensitivity to light
• Stiff neck
• Vomiting

When children should go to the emergency room for a fever

There are special considerations for treating very young infants and children with fevers. That’s because babies’ immune systems aren’t well-developed, and fevers can be signs of serious infection. According to the American Academy of Pediatrics, you should seek emergency medical care if your child:

• Is under 3 months old and has a temperature greater than 100.4 degrees
• Is 3 to 6 months old and has a temperature greater than 102 degrees with other symptoms
• Is 6 to 24 months old and has a temperature greater than 102 degrees that lasts more than 24 hours
• Has a fever that stays or repeatedly goes above 104 degrees
• Has a known heart condition or is immunocompromised

Other concerning symptoms include:

• Confusion or listlessness
• Difficulty breathing
• Irritability
• Rash
• Repeated diarrhea or vomiting
• Seizures
• Severe ear pain
• Severe headache
• Severe sore throat
• Stiff neck
• Looks ill or seems unusually drowsy

Get the emergency care you need

Sometimes a trip to the ER is necessary, and in that case, don't hesitate to head there. Other times, an urgent care facility can get you the help you need. If you or a loved one is experiencing a medical emergency, the most important thing is to not delay care.
