The U.S. Food and Drug Administration on Thursday approved a prescription treatment that can be used by family members or caregivers to treat a person known or suspected to have had an opioid overdose. Evzio (naloxone hydrochloride injection) rapidly delivers a single dose of the drug naloxone via a hand-held auto-injector that can be carried in a pocket or stored in a medicine cabinet.

It is intended for the emergency treatment of known or suspected opioid overdose, characterized by decreased breathing or heart rates, or loss of consciousness.Naloxone is a medication that rapidly reverses the effects of opioid overdose and is the standard treatment for overdose. However, existing naloxone drugs require administration via syringe and are most commonly used by trained medical personnel in emergency departments and ambulances.Evzio is injected into the muscle (intramuscular) or under the skin (subcutaneous). Once turned on, the device provides verbal instruction to the user describing how to deliver the medication, similar to automated defibrillators. Family members or caregivers should become familiar with all instructions for use before administering to people who are known or suspected to have had an opioid overdose. Family members or caregivers should also become familiar with the steps for using Evzio and practice with the trainer device, which is included along with the delivery device, before it is needed.
