Vicks VapoRub Harmful to Kids

Cold ointments may spell serious breathing problems for children

As far as home remedies go, it's right up there with chicken noodle soup. But parents who use Vicks VapoRub to help their children get over a cold may, in some instances, do more harm than good.

A new study published today in the journal Chest warns that putting the mentholated ointment under or in a child's nostrils can prompt mucus production and cause serious breathing problems.

"I think it will surprise some folks because it is used this way," said Bruce Rubin, professor and vice-chairman for research in the pediatrics department at the Wake Forest University School of Medicine in North Carolina and lead author of the study.

Although health professionals and product manufacturers have long known that using Vicks VapoRub and similar generic products on children can present risks, many parents may not be getting that message, Dr. Rubin said.

"I think most people aren't aware of [the risks] and I think most people don't read the warning label," he said.

The label on Vicks VapoRub, for instance, advises parents to consult a physician before using the product on children under age 2. A warning also states that the product shouldn't be rubbed in the nostril.

But the study said many parents or caregivers may miss, or even ignore, this warning, not realizing the harmful effects the product can have on very young children.

Dr. Rubin and his colleagues embarked on the study after taking care of an 18-month-old girl who was brought to the hospital with severe breathing problems. Doctors couldn't figure out what had caused the girl, who was suffering from a cold and hadn't been given any medication, to suddenly experience "severe respiratory distress."

After asking the child's grandparents to think of anything they may have done before she began to have trouble breathing, her grandmother said she had put Vicks under her nostrils less than an hour before.

After the child recovered, doctors at the hospital began to routinely ask about the use of mentholated ointments and found several cases were similar.

Researchers then began a study using ferrets, which have a similar airway to humans, to determine what could be causing the problem among young children. They found that Vicks VapoRub causes an increase in mucus, which can lead to serious problems among children. A child's airway is tightened and narrowed by a virus, and thus a significant increase in mucus can lead to serious breathing difficulties like those noted by Dr. Rubin and his colleagues.

That's not to say mentholated ointments don't provide relief. In adults, they deliver a cool sensation that tricks the brain into thinking airflow is increasing. In reality, the preparations don't act as a decongestant or help a person to breathe better. But they do make a person feel like they can breathe better, helping them feel more comfortable as they fight a cold.

The warning about the menthol-based ointment is particularly timely, considering health officials are moving to restrict the use of over-the-counter medications in children.

Last month, Health Canada warned that cough and cold medications shouldn't be given to children under 6 because there isn't enough information to prove they're effective. These medications were linked to some health problems among children in Canada in recent years, including five deaths.

It's possible the new restrictions on cold medications may prompt some parents to look more closely at alternative or home remedies to help their children. If that's the case, parents must understand that over-the-counter remedies that are used safely in adults could cause serious problems in kids.

"You need to be aware that unless these are studied in children, there might be unrecognized risks," Dr. Rubin said.

A Canadian pediatrician agreed that parents should be wary of giving children over-the-counter cold remedies, even if they're considered to be natural.

"A lot of the natural products on the market have not been tested," said Danielle Grenier, medical affairs director at the Canadian Paediatric Society. "Even if it's a natural product, it still has ingredients. We know that it can have side effects."

The best advice she has for parents is to rely on the simplest solutions to help your child through a cold: plenty of warm liquids and a lot of rest.

"They're still the best," Dr. Grenier said.
