NARCAN Nasal Spray delivers 4 mg of naloxone hydrochloride, a potent opioid antagonist designed for rapid emergency response to suspected opioid overdose. This package contains two single-dose devices for immediate administration. Naloxone works by blocking opioid receptors, quickly reversing respiratory depression and restoring normal breathing. Each device provides a pre-measured dose with straightforward nasal administration—no assembly required. Ideal for home, workplace, or community settings where opioid overdose risk exists. Always call emergency services immediately after administration. Keep accessible and check expiration dates regularly.
