FDA Approves Higher Dosage of Naloxone Nasal Spray to Treat Opioid Overdose

The U.S. Food and Drug Administration (FDA) announced on April 30, 2021 the approval of a higher dose naloxone hydrochloride nasal spray product to treat opioid overdose. The newly approved product delivers 8 milligrams (mg) of naloxone into the nasal cavity. The FDA had previously approved 2 mg and 4 mg naloxone nasal spray products.

Naloxone is a medicine that can be administered by individuals with or without medical training to help reduce opioid overdose deaths. If naloxone is administered quickly, it can counter the opioid overdose effects, usually within minutes. A higher dose of naloxone provides an additional option in the treatment of opioid overdoses.
