What is the most important information I should know about EVZIO?
EVZIO is used to temporarily reverse the effects of opioid medicines. The medicine in EVZIO has no effect on people who are not taking opioid medicines. Always carry EVZIO with you in case of an opioid emergency.
Use EVZIO right away if you or your caregiver think signs or symptoms of an opioid emergency are present, even if you are not sure, because an opioid emergency can cause severe injury or death. Signs and symptoms of an opioid emergency may include:
- unusual sleepiness and you are not able to awaken the person with a loud voice or rubbing firmly on the middle of their chest (sternum).
- breathing problems including slow or shallow breathing in someone difficult to awaken or they look like they are not breathing.
- the black circle in the center of the colored part of the eye (pupil) is very small, sometimes called “pinpoint pupils” in someone difficult to awaken.
- Family members, caregivers, or other people who may have to use EVZIO in an opioid emergency should know where EVZIO is stored and how to give EVZIO before an opioid emergency happens.
- Get emergency medical help right away after using the first dose of EVZIO. Rescue breathing or CPR (cardiopulmonary resuscitation) may be given while waiting for emergency medical help.
- The signs and symptoms of an opioid emergency can return within several minutes after EVZIO is given. If this happens, give additional injections using a new EVZIO auto-injector every 2 to 3 minutes and continue to closely watch the person until emergency help is received.
