Deaths from fentanyl will continue to rise and overdoses may be increasingly difficult to battle in the US, said Roger Crystal, who helped develop Narcan nasal spray, an easy-to-use medication that reverses overdoses.
The overdose crisis that killed more than 100,000 Americans in one year is “all about fentanyl”, Crystal said – and it’s only going to get worse.
Those who are overdosing from fentanyl have a shorter window of time to be saved and may need additional doses of the medication.
