NEW YORK (Reuters Health) -
At least 10 infant deaths in
Arizona in 2006 were linked to over-the-counter cough and cold
remedies — underscoring the danger of giving the medications
to children younger than 2, researchers report.

The investigators found that of 21 infants who died
unexpectedly and had autopsy data available, 10 had evidence
that they been given cough or cold medication shortly before
they died.

The findings, published in the journal Pediatrics, do not
prove that the medications caused or contributed to the
infants' deaths, but they add weight to a recent warning from
the Food and Drug Administration (FDA) that parents not give
cough and cold remedies to children younger than 2.

“We strongly recommend that parents not use these
medications,” said Dr. Mary Ellen Rimsza of the University of
Arizona College of Medicine in Tucson, the lead researcher on
the new study.

Cold and cough medications typically contain a combination
of decongestants, antihistamines and cough suppressants — all
of which can have serious side effects in young children,
including increased blood pressure, heart rate disturbance, and
depressed breathing.

While these dangers are now recognized, until now no study
had examined the possible role of cough and cold medications in
unexplained infant deaths.

Rimsza and colleague Susan Newberry base their findings on
data routinely collected by the state of Arizona on child
deaths. In 2006, there were 90 unexpected infant deaths,
including 42 that were attributed to an injury or suffocation.
The researchers focused on the remaining 48 deaths, of which 21
had autopsy data.

Of those 21 cases, the researchers found, toxicology
reports showed evidence that 10 infants had been given cough
and cold medication soon before their deaths.

However, only one death had actually been attributed to
cough and cold medication; “respiratory illness” was listed as
the cause of death in six cases, while sudden infant death
syndrome was blamed in another two.

Whether the medications led to any of these deaths is
unclear, but the bottom line for parents remains the same,
Rimsza told Reuters Health: Don't give the drugs to infants.

There are also concerns about the safety of cold and cough
remedies for older children.

In fact, an expert advisory panel to the FDA has
recommended that parents refrain from giving the medications to
children younger than 6. The FDA is still reviewing the data on
that question.

Rimsza told Reuters Health that as a pediatrician, she
agrees with the stance of the advisory panel. Parents may
assume that over-the-counter means “safe,” she noted, but in
fact, cough and cold medications have never been proven safe
and effective for children of any age.
