  • Teva-Naloxone Nasal Spray is available as a 4 mg nasal spray device.

How to use Teva-Naloxone Nasal Spray

Step 1: Identify Opioid Overdose & Call for Emergency Medical Help

Check for signs of an opioid overdose:
•    Person DOES NOT wake up after you shout, shake their shoulders, or firmly rub the middle of their chest.
•    Breathing is very slow, irregular or has stopped.
•    Centre part of their eye is very small, like a pinpoint. 

Call 911 or ask someone to call for you. 
Lay the person on their back.

Step 2: Give Teva-Naloxone Nasal Spray

Remove device from packaging. Do not test the device. There is only one dose per device.
Tilt the person’s head back and provide support under their neck with your hand.
Hold the device with your thumb on the bottom of the plunger. Put your first and middle fingers on either side of the nozzle.
Gently insert the tip of the nozzle into one nostril. Your fingers should be right up against the nose. If giving to a child, make sure the nozzle seals the nostril.
Press the plunger firmly with your thumb to give the dose.
Remove the device from the nostril.

Step 3: Evaluate and Support

Move the person on their side in the recovery position. Watch them closely.

Give a second dose after 2 to 3 minutes if the person has not woken up or their breathing is not improved. Alternate nostrils with each dose.     

You can give a dose every 2 to 3 minutes, if more are available and are needed. 

Perform artificial respiration or cardiac massage until emergency medical help arrives, if know how and if it is needed.
