Immediate-release opioids to carry "black box" warning label

More than 40 people die a day from opioid overdoses, CDC says

(CNN) In an attempt to help slow the prescription drug abuse epidemic, the U.S. Food and Drug Administration announced Tuesday that immediate-release opioid painkillers such as oxycodone and fentanyl will now have to carry a "black box" warning about the risk of abuse, addiction, overdose and death.

Prescription opioid painkillers are divided into two main classes -- extended release, which have more pain-killing opioid per dosage, and immediate release, which have less opioids, but need to be taken more frequently. Ninety percent of opioid prescriptions are for immediate-release painkillers, the FDA said.

The "black box" warnings are the FDA's strongest, and they're meant to educate doctors as they're prescribing medications to patients.

Here's how the warning will play out for consumers, according to the FDA.

When a patient gets his or her prescription filled, the bottle should have a notification indicating there is a black-box warning for the drug. The consumer would need to go to the manufacturer's website for details.
