How to use the auto-injector

Step 1.

Firmly pull the auto-injector from the outer case. See Figure B.

Pull apart to remove outer case of Kaleo's naloxone hydrochloride auto-injector.

Do not go to Step 2 (Do not remove the Red safety guard) until you are ready to use the auto-injector. If. you are not ready to use the auto-injector, put it back in the outer case for later use.

If naloxone hydrochloride injection auto-injector is frozen, do not wait for it to thaw. Use another auto-injector if available. If another auto-injector is not available, get emergency medical help right away.

Naloxone hydrochloride injection auto-injector may still be used if it has been thawed after being previously frozen.

Step 2.

Pull off the Red safety guard. See Figure C.

To reduce the chance of an accidental injection, do not touch the Black base of the auto-injector, which is where the needle comes out.

Pull down to remove the red safety guard on the naloxone hydrochloride auto-injector.

Note: The Red safety guard is made to fit tightly. Pull firmly to remove.

Do not replace the Red safety guard after it is removed.

Step 3.

Place the Black end of the auto-injector against the outer thigh, through clothing or personal protective equipment (including MOPP4 PPE), if needed. Make sure that the injection site is free of other materials such as equipment or other obstructions, except for clothing.

Press firmly until you hear a click and hiss sound and then hold in place for 5 seconds. See Figure D.

Note: The auto-injector makes a distinct sound (click and hiss) when it is pressed against the thigh. The click and hiss indicates the start of the injection. This is normal and means that the auto-injector is working correctly. Keep the auto-injector firmly pressed against the thigh for 5 seconds after you hear the click and hiss sound. After the medicine is injected, the needle will retract back up into the auto-injector and is not visible after use.

Step 4.

After administering the first dose of Naloxone hydrochloride injection, get emergency medical help right away.

If symptoms return, additional naloxone may be administered.
