Where in the world did you hear?
You should get one of those over-the-counter cold remedies to relieve your child’s symptoms.
Sound Advice
Save your money. Most cold “remedies” are worthless in children. Virtually every cold medicine contains the same two ingredients: an antihistamine and a decongestant, neither of which addresses the basic causes of cold symptoms. Mucus, congestion, fever and cough are caused, in large part, by cytokines and leukotrienes, inflammatory proteins produced by the body in response to infection, not histamine. And yet, almost every popular over-the-counter medicine contains antihistamines, drugs appropriate for treatment of allergies, not colds. Most studies in children show these medications are useless and, worse,they often produce side effects of irritability and whining. Parents can be misled into thinking the child’s illness is getting worse, not realizing that the treatment itself is responsible for the misery. They can only hope that their fussy children will, at least, become sleepy from the antihistamine. But often, just the opposite occurs: the kids become “wired” and won’t sleep at all. And decongestants, the other ingredient in cold medicines, whether combined with antihistamines or packaged separately are troubling as well, capable of causing sweating, restlessness, elevated blood pressure and cardiac excitation with minimal or no relief of cold symptoms, another poor choice.
You might then ask if over the counter cough medicines have a better track record. Sorry you asked, because the answer is no. Most cough medicines that advertise relief from day coughs, night coughs, mucusy coughs, fever, headache and achy muscles are equally ineffective. Studies in children fail to show any significant shortening of cough symptoms compared with cough drops and increased fluid consumption. The reason is that the main ingredients in most over-the-counter cough medicines are the same as in the cold remedies except for the addition of “expectorants,” compounds to help thin the mucus. They don’t.
And why combine these ineffective cold or cough medicines with acetaminophen or ibuprofen? It doesn’t make therapeutic sense but lots of manufacturers do just that. In the absence of fever or pain, those drugs are inappropriate and, in some cases, can interfere with the body’s production of antibodies, thereby prolonging the illness. Not to mention that by combining medications, it is difficult if not impossible to administer the correct dose of each individual medicine.
So, are we left with nothing? Isn’t any treatment available to relieve the symptoms of the common cold? The answer is yes, it’s simple and inexpensive: nasal saline, a solution of salt and water. This remedy is remarkably effective in liquefying nasal mucus and helping to alleviate the post- nasal drip cough that accompanies most colds. Spraying or dropping saline into the nose several times a day and, especially, before going to sleep helps to move mucus out of the nose without side effects. It works and it can be made at home. How? Add 1/4 teaspoon to 8 ounces of tap water, boil and cool. That’s it.
Children should be encouraged to drink plenty of fluids to keep mucus as thin as possible. It used to be thought that milk and dairy products should be avoided during respiratory illnesses, believing that the mucus would become thicker. Not true. Milk is a good fluid source and can be used at will. Running a humidifier or a vaporizer with plain water, hot or cold, will add moisture to the inhaled air and lubricate the linings of the respiratory tree, soothing and effective. Adding menthol or any other “medication” to the evaporating water is not a great idea. Studies have failed to show that additives are helpful and some may even irritate the tender linings of the nose and respiratory tree resulting in a greater production of mucus. Fever, headaches and muscle pains usually respond nicely to the correct dose of either acetaminophen or ibuprofen. The good news is that all colds have a relatively short existence, disappearing within one to two weeks no matter what treatment is used
Newer medications are becoming available and may soon be used in the treatment of the common cold. One of the most promising is a medication called montelukast, an oral medication that blocks leukotriene, an inflammatory protein which increases congestion. More specific anti-inflammatory medications are surely on the way as are vaccines to immunize against many of the viruses which cause the common cold.
