Opioids are a class of drugs used for the management of pain. Opioids can affect the part of the brain that controls breathing. 

Anyone using prescribed or street opioids can have an overdose, but there are some things that put you at higher risk, such as: 

• taking prescription opioids more often or at higher doses than recommended
• taking opioids with alcohol or sedatives, such as:
  • sleeping pills
  • muscle relaxants
  • benzodiazepines
• injecting drugs
• taking an opioid your body isn't used to, or switching to a stronger drug
• taking higher doses than you are used to
• using drugs of unknown purity or strength
• other health conditions, like liver or kidney disease, or breathing problems

Teva-Naloxone Nasal Spray should be used immediately if you or your caregiver think signs or symptoms of an opioid emergency are present, because an opioid emergency can cause severe injury or death.

Always call 911 as soon as an opioid overdose is suspected, before administering Teva-Naloxone Nasal Spray. 

It is important to be familiar with the signs of an opioid overdose by recognizing these symptoms:
