A review of past research finds that fever-reducing drugs
have no effect on the speed of children's recovery from an infection, contrary
to the fears of some doctors and parents. Researchers have debated for decades
whether lowering a sick child's fever helps the recovery process or interferes
with the body's ability to fight the infection.
Some previous research has shown that giving children
fever-reducing "antipyretic" medications, such as acetaminophen,
after vaccinations interfered with their immune responses to the vaccines, for
example."There's no evidence that antipyretics slow down recovery,"
said Alison While, a professor of community nursing at King's College London
and senior author of the new study.
Nevertheless, While and her coauthor caution in their report
in the Journal of Paediatrics, their findings don't mean they encourage parents
to use the medications at the first sign of fever either. "Many many
parents are using antipyretics with small children whenever they get a slightly
raised temperature. This is madness," While told Reuters Health.
Reducing a fever
Because of the ongoing debate and the fact that few
researchers have examined the health benefits or harms in reducing a fever
during illness, While and colleague Edward Purssell combed the literature. They
found only six clinical studies that examined the effect of using anti-fever
medications on a total of 657 sick children. Three of the studies focused on
children infected with malaria and the rest included fevers that came from
chickenpox and other viral infections.
Feverish children given anti-fever meds returned to normal
body temperature four hours more quickly than those without meds, on average,
but all children recovered from their respective infections with equal speed,
the researchers found. For While and other health experts, the result not only
shows that antipyretics do no harm to recovery time, it also highlights
parents' quick willingness to stave off a fever, with little evidence it does
"Fever-phobia - this great fear that fever is such a
horrible thing for their child" drives the overuse of anti-fever meds by
parents, according to Dr Janice Sullivan, medical director of the Kosair
Charities Paediatric Clinical Research Unit at the University of Louisville.
Sullivan, who was not involved in the current study, coauthored 2011 American
Academy of Paediatrics recommendations to decrease use of anti-fever medicines
Giving your child drugs
when they sick
The bottom line is this: You never want to give your child a
drug that they don't truly need because all drugs, even if you can buy them
over the counter, have a potential for side effects," Sullivan told
Reuters Health."They can cause injury to the liver for acetaminophen and
to the kidney for ibuprofen; they're not benign drugs," Sullivan said.
The deciding factor in giving antipyretics is typically
discomfort, Sullivan added. If children are whiny, have aches and joint pain,
they may need to be treated, but otherwise, a fever temperature will limit
itself and won't require treatment, Sullivan said.
She recommended that parents talk with their pediatricians
about what symptoms beyond fever should be of concern and may warrant a
doctor's visit. For example, a child with a weakened heart won't do well with a
fever and could benefit from anti-fever meds. Another expert went further,
saying that anti-fever meds had no place in a medicine cabinet.
"A true fever, caused by an infectious agent is never
harmful; there's no reason why one should lower the temperature during
infection," said Dr Peter Kremsner, head of the Institute of Tropical Medicine
at the University of Tubingen in Germany, and an author of three malaria
studies included in the analysis.
One common worry among parents is that a high fever could
overwhelm a child's body and lead to convulsions. Kremsner said no evidence
suggested that convulsions from fever existed. "It is always the
infectious disease," he told Reuters Health.
