In a report released by the Centers for Disease Control and Prevention this month, drug overdoses in the U.S. rose again in 2014, driven by surges in deaths from heroin and powerful prescription painkillers such as Vicodin and Oxycontin. Overall, overdose deaths in the U.S. surpassed 47,000 — up 7 percent from 2013. (AP Photo/Toby Talbot, File)

Prevent poisoning:

* Store medicine away from food and household products * Keep medicine and household products in original containers * Use child-resistant packaging and store medicine and cleaners above floor level. * If it's medicine, call it medicine, not candy. * Take medicine where children can't watch. * Always turn on the light when using medicine, never take medicine in the dark. * Call Tennessee Poison Center for help at 1-800-222-1222
