IMPORTANT WARNING
[Posted 01/12/2007] The Centers for Disease Control and Prevention (CDC) issued a Morbidity and Mortality Weekly Report (MMWR) article describing three deaths in U.S. infants aged less than 12 months associated with cough and cold medications. These medications were determined by medical examiners or coroners to be the underlying cause of death. The cases described in this report underscore the need for clinicians to use caution when prescribing and caregivers to use caution when administering cough and cold medications to children aged less than 2 years.
