Synthetic Opioid Potentially More Potent Than Fentanyl Detected in Austin Area, EMS Warns

Austin, TX, September 25, 2026 —

Austin Travis County Emergency Medical Services (EMS) has issued a warning regarding the potential presence of cychlorphine, a synthetic opioid described as more potent than fentanyl, within the Austin and Travis County region. The suggestion stems from recent overdose responses that have exhibited characteristics of Narcan resistance, according to the EMS.

The exact number of overdose responses indicating this potential threat was not specified. Similarly, details regarding the specific nature or frequency of the Narcan resistance observed in these incidents were not provided. The primary concern highlighted by Austin Travis County EMS is that cychlorphine, if present, represents a significantly more dangerous substance due to its heightened potency compared to fentanyl, an opioid that has already been a major focus in overdose prevention efforts nationwide.

Cyclorphine is a synthetic opioid that has been identified in other regions, often associated with a higher risk of overdose due to its strength. The resistance to Narcan (naloxone), a medication used to rapidly reverse opioid overdoses, suggests that standard doses may not be effective, requiring more aggressive or repeated administration. This poses a critical challenge for first responders in managing overdose situations.

Austin Travis County EMS is monitoring the situation closely. The announcement serves as an alert to the public and healthcare providers to be aware of the potential emergence of this highly potent synthetic opioid. Further information regarding the scale of the potential issue or specific cases has not been released.
