The Risks of Pediatric Cough Medicine

Choosing the right pediatric cough medicine can be difficult for parents since a cough in kids is one of the more frustrating symptoms to treat.

Not only can coughing keep your kids up all night, but it can also get them sent home from school if the coughing is very distracting to other students in the class. But parents often run into trouble when trying to find a cough syrup to quiet their child's cough.

Cold and Cough Syrup Warnings

Unfortunately, an FDA public health advisory about children's cold and cough syrups states that "questions have been raised about the safety of these products and whether the benefits justify any potential risks from the use of these products in children, especially in children under two years of age."

Warnings on cold and cough syrups even said that they shouldn't be given to children under age four. Since the advisory's release, the FDA has reminded parents not to give small children or infants the pediatric cold and cough products that remain on the market and are designed for older children. Children under two years old should never be given cold and cough products with decongestants and antihistamines, without first seeking medical advice.

The FDA reports that most problems with cold and cough syrups occur when "more than the recommended amount is used, if it is given too often, or if more than one cough and cold medicine containing the same active ingredient are being used." But since there is little proof that these medicines actually work, experts recommend that parents avoid them.

Cough Syrups

Medicines that are supposed to help quiet coughs (antitussive medicines) usually include one or more of these ingredients, including:

  • Benadryl (an antihistamine)
  • Dextromethorphan (the 'DM' in cough syrups)
  • Codeine or hydrocodone (narcotic cough suppressants)

Many cough syrups also contain alcohol.

Multi-symptom cold and cough syrups may also contain a decongestant, expectorant, or pain and fever reducer.

Commonly used cough medicines and cough syrups include:

  • Robitussin DM
  • Delsym
  • Children's Triaminic 
  • PediaCare Long-Acting Cough

Cough syrups with codeine and hydrocodone are available only by prescription.

Do Cough Syrups Work?

One of the biggest factors in the debate over the use of cold and cough syrups in children is the evidence, or lack of evidence, that they actually work.

Although many parents and pediatricians are often sure that cold and cough syrups do indeed work when a child is coughing, that is usually based on anecdotal evidence and not based on scientific research.

But what about all of the evidence that states that cough medicines don't work? Unfortunately, most of it isn't that good. One large review of these studies from the Cochrane Reviews concluded that "there is no good evidence for or against the effectiveness of OTC medications in an acute cough.

The results of this review have to be interpreted with caution because the number of studies in each category of cough preparations was small. Many studies were of low quality and very different from each other, making the evaluation of overall efficacy difficult."

One problem is that kids cough for a lot of different reasons. For example, they might have a cough when they have croup, which is often characterized as difficult to control, bronchitis, asthma, allergies or the common cold.

Since parents still seem to be using these cold and cough syrups, even with the warnings, hopefully, more research can be done to see if they are helpful for some children. Then, more work can be done to make them safer for all children.


So if your child is coughing and you are supposed to use a cold and cough syrup for your younger child, what are you supposed to do?

Some alternative remedies to using a cough syrup that may be helpful include:

  • Cool air humidifier
  • Drinking extra fluids
  • Rest and decreased activity, especially avoiding physical activity that may make a cough worse
  • Saline nasal drops, with bulb suctioning for newborns and infants
  • Cough drops for children over age 4 or 5 for which they aren't a choking hazard

Call your pediatrician if your child has a cough and trouble breathing, a non-stop cough, a cough, and high fever, or a cough that isn't going away or getting better after five to seven days.


Unfortunately, many kids abuse drugs. And these days, it goes far beyond "traditional" drugs, such as marijuana, alcohol, ecstasy, cocaine, and heroin.

Many teens now actually abuse dextromethorphan (also called DXM), which is found in cough syrups. Or they may abuse a combination cold medicine like Coricidin HBP Cough and Cold, which is also known as "Triple C."

In addition to dextromethorphan, Coricidin HBP Cough and Cold also contain an antihistamine. Large doses can cause teens to have hallucinations and other serious side effects. There have even been reports of deaths from kids abusing DXM and Coricidin.
