Best way to manage fever in children
Controlling fever is a major issue for both parents and the health professionals
who care for children. When a child gets a fever, worried parents
commonly call the doctors office. They wonder whether the
child should be seen and how best to treat the fever at home.
Years ago, childrens aspirin was the drug of choice in reducing
fever. When giving aspirin to children was linked with a dangerous
condition called Reyes syndrome, doctors began recommending
acetaminophen (brand name Tylenol
®
).
Until recently, it was the drug most commonly used to treat fever.
Then a third drug, ibuprofen, marketed as Advil
®
or Motrin
®
, came on the market
in pediatric strength, making the decision over which fever reducer
to use more complicated.
Alternating Tylenol and Advil to reduce fever has
confused parents and may even be dangerous.
Now, some doctors are suggesting that parents use both Tylenol and
Advil to reduce fever, with a few recommending alternating the medications
every dose. Understandably, this has led to confusion among parents
and concerns among doctors that children will not receive the proper
dose.
This concern was highlighted in a study in the May issue of Pediatrics.
Pediatric researchers from Winthrop University Hospital in New York
found that indeed, alternating these medications is a common practice
in some groups and can indeed be confusing and even dangerous. They
cited instances where the practice may have led to overdoses of pain-relieving
medications in children. Whats more, they found no evidence
that this type of fever management benefited children. Finally, they
noted the practice is not recommended by the American
Academy of Pediatrics, a belief held by some pediatricians.
When should fever be treated?
To loosely determine how widespread the practice of alternating
pain medications had become, the team recruited practicing pediatricians
to fill out a 15-question survey. The survey asked:
- whether the pediatrician
recommended his patients alternate fever-reducing medications
- the degree of temperature
at which medication therapy should be started
- what documentation
supported the use of alternating medications
- how long the doctor
had been in practice and whether it was a solo or group practice.
In all, 161 doctors returned
the surveys, which showed that nearly two-thirds (61.9 %) of respondents
began fever therapy at a temperature of 101 degrees F. A smaller figure,
13 percent, used patient discomfort as the guideline for when they
recommended treatment.
Researchers noted there is presently no scientific
evidence that this combination is safe or achieves faster fever relief
than using one of the products alone.
Which medication is best?
The researchers noted that for half of the respondents, which medication
was chosen depended on how high the fever was: 57 percent chose ibuprofen
for temperatures of 102 degrees F or higher. Finally, half of the
physicians told parents to alternate acetaminophen and ibuprofen,
with younger doctors (those with less than five years of practice)
more likely to recommend switching back and forth (69.7 percent).
The researchers noted that there is presently no scientific evidence
that this combination is safe or achieves faster fever relief than
using one of the products alone.
The American Academy of Pediatrics position
Nearly one third (29 %) of the pediatricians surveyed said they used
both medications because the American Academy of Pediatrics has made
that recommendation. In reality, there is currently no policy or recommendation
that exists.

Controlling
fever in children
More
than almost any other common condition, fever causes great worry
in parents. They look at their red-cheeked child and wonder if the
fever itself can somehow harm their child or if its a sign
that a more serious illness is present. Indeed, the majority of
the calls to our practice are related to fevers in children.
"In most cases, fever is not serious and if anything, its
a good sign the childs body is working to fight off an illness."
One common myth is that the higher the fever, the worse the illness.
Obviously, extremely high fevers over 104 degrees F call for action,
but usually there is not much difference between a 100 degree fever
and a 102 degree fever. In most cases, fever is not serious and, if
anything, its a good sign that the childs body is working
to fight off an illness. Since many types of bacteria and viruses
dont like hot temperatures, fever is natures way of fending
off disease.
Of course, even knowing this, parents often wish to give their children
some type of medication to lower the fever and make the child more
comfortable, which is very understandable. So by and large, when we
recommend the use of these medications, it is as a comfort measure.
Parents often ask if they should wake their child to give them the
medicine. We feel that letting the child sleep is the best thing to
do and then give the medication when she or he wakes up. That also
might be a good time to offer a drink of clear liquids like water
to make sure the child stays well hydrated.
"Any infant age three months or younger with a fever is immediately brought in for an exam."
When to call the doctor
Any infant age three months or younger with a fever is immediately
brought in for an exam. After that, the data is less absolute. The
American Academy of Pediatrics recommends parents call their pediatrician
within 24 hours for fever in children a year old or less. You should
also call if other symptomssuch as neck pain, vomiting or diarrheaare
present.
Deciding which medication to use
As for which medication to give, we recommend parents try Tylenol®
first. If the fever does not go down after 30 to 45 minutes, we will
then recommend giving the appropriate dose of ibuprofen on top of
that. Then, parents should stick with the single medication that worked
best. We dont suggest they switch back and forth.
"Avoid giving too much medication, which can be very dangerous."
To avoid overdosing, parents should write down when medication was
given, especially for those doses given in the middle of the night
or if there is more than one sick child in the house. You want to
avoid giving too much medication, which can be very dangerous. When
it comes to a childs medication, more is not better.
We suggest using Tylenol (acetaminophen) first because, when taken
properly, its one of the safest medications available. Sadly,
though, acetaminophen poisoning can and does happen and can lead to
liver failure. Its a leading reason why children undergo liver
transplants.
Confusing packaging, dosage information
Parents should know that these medications come in different strengths.
Infant drops are extremely concentrated, so use less. Always use the
measuring device that comes with the medication. If it came with a
dropper, use the dropper. If it comes with a cup, use only the cup.
Be very cautious about using cold medications, which often also contain
either acetaminophen or ibuprofen. We usually dont recommend
these combination medications because, for one thing, the cold products
dont work in children younger than two years old. And theres
the potential for overdosing. So read labels very carefully.
To help with dosing information, our practice includes a simple dosing
chart in the baby books we give out. Its also reasonable to
call your local pharmacist for simple dosage questions.
