Medicine / Dosages


NOTE: New Concentration for Infants. In accordance with FDA recommendations, acetaminophen manufacturers have changed the concentration of infant acetaminophen from 80mg/0.8ml to 160mg/5ml. Be aware that there may be both the old and new concentrations of infants' acetaminophen products available in stores and in medicine cabinets. The pediatric acetaminophen products currently on the market can continue to be used as labeled. Be sure to check the label or contact our office should you have questions. More Information
