GREATER ASSURANCE DURING AN OPIOID
OVERDOSE EMERGENCY RESCUE SITUATION

There is no way to know how much naloxone will be needed to restore normal respiration during an opioid overdose
emergency. When you consider all the uncertainties associated with an overdose—such as how much a patient has
taken or how long they haven’t been breathing—having a wider safety net could be beneficial.6

High-dose intramuscular naloxone administration could be the difference.

≈50%

OF OPIOID REVERSALS

are estimated to require more
than 1 dose of naloxone7

4-mg INTRANASAL DOSE

of naloxone has only 44% of the
relative bioavailability* compared with
a 0.4-mg intramuscular injection8

“…if a patient is experiencing profound respiratory depression that could lead to death, the risks of precipitated withdrawal are outweighed by the need to restore respiration quickly before brain injury or death occur.”11

INDICATION

ZIMHI is an opioid antagonist indicated for the emergency treatment of known or suspected opioid overdose, as manifested by respiratory and/or central nervous system depression in adult and pediatric patients. ZIMHI is intended for immediate administration as emergency therapy in settings where opioids may be present. ZIMHI is not a substitute for emergency medical care.

IMPORTANT SAFETY INFORMATION

As the duration of action of naloxone hydrochloride is shorter than many opioids, keep the patient under continued surveillance and administer repeated doses of naloxone using a new ZIMHI device, as necessary, while awaiting emergency medical assistance.

Reversal of respiratory depression caused by partial agonists or mixed agonists/antagonists, such as buprenorphine and pentazocine may be incomplete. Repeat doses of ZIMHI may be required.

Use in patients who are opioid dependent may precipitate opioid withdrawal. In neonates, opioid withdrawal may be life-threatening if not recognized and properly treated. Monitor for the development of signs and symptoms of opioid withdrawal.

Abrupt postoperative reversal of opioid depression may result in adverse cardiovascular (CV) effects. These events have primarily occurred in patients who had pre-existing CV disorders or received other drugs that may have similar adverse CV effects. Monitor these patients closely in an appropriate healthcare setting after use of naloxone hydrochloride.

After use, the ZIMHI needle is exposed until the safety guard is deployed. A needlestick injury could occur during use in emergency situations. In the event of accidental needlestick injury, medical attention should be sought.

The following adverse reactions were most commonly observed in ZIMHI clinical studies: dizziness, lightheadedness, and elevated bilirubin.

To report SUSPECTED ADVERSE REACTIONS, call 1-800-230-3935 or FDA at
1-800-FDA-1088 or www.fda.gov/medwatch
