FDA approves new nasal spray to reverse opioid overdoses.

The FDA has approved Opvee, a nasal-spray medication that can reverse overdoses caused by synthetic opioids, including fentanyl. However, some public health experts, physicians, and community groups are concerned about the cost and potential side effects of the drug. Opvee is a more potent medication than naloxone, which is widely used to reverse overdoses, and may cause agonizing, long-lasting withdrawal symptoms for some drug users after they are revived. Critics argue that cheaper, proven medications such as naloxone are sufficient to combat overdose deaths.
