JACKSON, Miss. (WTVA) - A drug used to reverse effects of an opioid overdose is now available through Mississippi pharmacies. 

A doctor's prescription is not required, stated the Mississippi State Department of Health. 

Today, May 31, the MSDH released a statement saying the drug naloxone, commonly called Narcane, is now available by request directly from a pharmacist at all Mississippi pharmacies. 

During the event of an overdose, the drug blocks the brain's opioid receptors and restores normal breathing in people who have overdosed on fentanyl, heroin or prescription opioid painkillers. 

This temporary blocking effect allows time for professional medical attention to be sought. 

"Expansion of the availability and use of this drug could greatly reduce drug overdose deaths and save lives," said MSDH Officer Dr. Mary Currier. "It's important that Mississippians – any family member, friend or other person in a position to help someone suffering from an opioid overdose – are aware of the availability of this drug and know how to administer it if the need arises." 

The MSDH says the drug has no effect on someone not using opioid drugs.
