LOUISVILLE, Ky. and SAN DIEGO, March 31, 2022 (GLOBE NEWSWIRE) -- USWM, LLC (US WorldMeds), and Adamis Pharmaceuticals Corporation (NASDAQ: ADMP), today announced the U.S. launch and availability of ZIMHI™ (naloxone HCL Injection, USP) 5 mg/0.5 mL. ZIMHI is a high-dose naloxone injection product FDA-approved for use in the treatment of opioid overdose as emergency therapy in settings where opioids may be present.

According to the Centers for Disease Control and Prevention (CDC), drug overdoses are now the leading cause of death for Americans under age 50, with more powerful synthetic opioids, like fentanyl and its analogs, responsible for the largest number of those deaths. Approximately 85% of all opioid overdose related deaths are now caused by fentanyl, fentanyl analogs, and other synthetic opioids. Drug overdoses resulted in over 100,000 deaths in the United States during the 12-month period ending April 2021, which was a 29% increase over the prior 12-month period.

“ZIMHI represents an important new tool for caregivers and patients by combining an intuitive, compact, and simple to use intramuscular device with a high dose of naloxone. Successfully treating overdoses involving fentanyl often requires multiple doses of lower-dose or intranasal naloxone products, creating an urgent need for new tools to help combat these more powerful opioids,” said P. Breckinridge Jones, Sr., CEO of US WorldMeds.

Dr. Dennis J. Carlo, President and CEO of Adamis, stated, “ZIMHI provides the highest intramuscular dose of naloxone among naloxone injection devices currently available. We are very excited to once again partner with US WorldMeds to launch ZIMHI. We believe that ZIMHI will play a pivotal role in the treatment of opioid overdose, while contributing positively to the entire community that has been impacted by the opioid epidemic.”

ZIMHI is available with discounted public interest pricing for first responders and other community health organizations, with additional information available via email to [email protected] or at

Patient accessibility is further enhanced with a co-pay program that provides ZIMHI to eligible patients for as little as $0. Most pharmacies across the country are covered through the program with savings being automatically applied.

Physicians, pharmacists or other healthcare providers with questions about ZIMHI should visit

ZIMHI is an opioid antagonist indicated in adult and pediatric patients for the emergency treatment of known or suspected opioid overdose, as manifested by respiratory and/or central nervous system depression. 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 for Patients
Do not use ZIMHI if you are allergic to naloxone hydrochloride or any of the ingredients in ZIMHI. ZIMHI is used to temporarily reverse the effects of opioid medicines. The medicine in ZIMHI has no effect in people who are not taking opioid medicines.

Use ZIMHI right away if you or your caregiver think signs or symptoms of an opioid emergency are present, even if you are not sure, because an opioid emergency can cause severe injury or death. Family members, caregivers, or other people who may have to use ZIMHI in an opioid emergency should know where ZIMHI is stored and how to give ZIMHI before an opioid emergency happens. Get emergency medical help right away after using the first dose of ZIMHI. Rescue breathing or CPR (cardiopulmonary resuscitation) may be given while waiting for emergency medical help.

The signs and symptoms of an opioid emergency can return within several minutes after ZIMHI is given. If this happens, give additional injections using a new ZIMHI prefilled syringe every 2 to 3 minutes and continue to closely watch the person until emergency help is received.

ZIMHI may cause serious side effects, including sudden opioid withdrawal symptoms, which may include: body aches, fever, sweating, runny nose, sneezing, goose bumps, yawning, weakness, shivering or trembling, nervousness, restlessness or irritability, diarrhea, nausea or vomiting, stomach cramping, increased blood pressure, or increased heart rate.

Other common side effects of ZIMHI include dizziness and injection site redness. In infants under 4 weeks old who have been receiving opioids regularly, sudden opioid withdrawal may be life-threatening if not treated the right way. Signs and symptoms include: seizures, crying more than usual, and increased reflexes.

These are not all of the possible side effects of ZIMHI. Call your doctor for medical advice about side effects. To report SUSPECTED ADVERSE REACTIONS, contact Adamis Pharmaceuticals Corporation at 1-858-997-2400 or FDA at 1-800-FDA-1088 or
