EVZIO (naloxone hydrochloride injection)
SELF INJECTION
Indications for Prior Authorization:
- Emergency treatment of known or suspected opioid overdose, as manifested by respiratory and/or central nervous system depression.
Patients must meet the following criteria for the indications above:
Opioid Overdose
- The patient may have access to opioids AND
- Medical justification supported by chart note documentation why the patient cannot use Narcan (naloxone nasal spray) AND naloxone injection (non-auto-injector formulation for use with a standard syringe)
The following indications do not meet the criteria for use established by the Western Health Advantage Pharmacy and Therapeutics Committee:
- Non-FDA approved indications, which are not listed in the Approved Indications section, unless there is sufficient documentation of efficacy and safety in the published literature (2 peer reviewed sources required).
General Information:
- Evzio is intended for immediate administration as emergency therapy in settings where opioids may be present.
- Evzio is not a substitute for emergency medical care. If the desired response is not obtained after 2 or 3 minutes, another Evzio dose may be administered. If there is still no response and additional doses are available, additional Evzio doses may be administered every 2 to 3 minutes until emergency medical assistance arrives. If no response is observed after 10 mg of naloxone hydrochloride have been administered, the diagnosis of narcotic-induced or partial narcotic induced toxicity should be questioned. Additional supportive and/or resuscitative measures may be helpful while awaiting emergency medical assistance.
- Clinical efficacy studies were not conducted for Evzio. In one pharmacokinetic study of 30 patients, a single Evzio injection provided equivalent naloxone compared to a single dose of naloxone injection using a standard syringe.
