The patient is lying on the ground, has constricted pupils, slurred speech, normal breathing and responds to your questions. What is an appropriate action to take? A. Administer one dose of IN naloxone B. Administer two sequential naloxone doses ASAP C. Call EMS and monitor patient for worsening symptoms D. Call law enforcement to arrest patient

Find a good lawyer B. You are covered under the Good Samaritan Law C. Talk to your state representative D. Discuss the matter with your friend first to see if they want to press charges

8 Pre-Question #5 A Russian speaking patient with no health insurance is requesting a recommendation for naloxone product to treat opioid overdose for her mother in the event it is needed. What is the best product to recommend? A. Intranasal Spray B. Intranasal Syringe C. Intramuscular Autoinjector D. A or B E. B or C

9 Agenda What is the landscape of the opioid epidemic? What is naloxone and its role in therapy? What are the differences in naloxone products? Who can give or receive naloxone? How do you administer naloxone? What are the access laws? What are resources available to providers/patients?

11 The Opioid Epidemic- National 115 Americans die daily from opioid overdose Economic burden: $78.5 Billion annually 2015: 33,000 deaths, 2M opioid related substance use disorders (likely more) 80% of people who use heroin tend to first abuse prescription opioids Epidemic designation from President Trump in 2017 drugabuse.gov
