Isotonitazene (iso) – A new synthetic opioid discovered as powerful as fentanyl
Isotonitazene — commonly referred to as “iso,” is a new synthetic opioid as powerful as fentanyl. Iso is a synthetic version of etonitazene, an opioid first reported in 1957, which is nationally and internationally controlled, as it is highly addictive and very dangerous. However, iso is not yet on the U.S. Drug Enforcement Administration‘s controlled substances list, meaning it is not illegal. While the toxicity of isotonitazene has not yet been widely studied, it is of public health concern because of recent associations with drug user death, and it is believed that this new opioid holds the potential to cause widespread harm.
Although the size of the iso market is unknown, it is known to be sold online as a legal replacement to controlled opioids. Researchers found most iso comes in a yellow or off-white powder that can be cut into other drugs. It is being shipped from China, and is being pressed into counterfeit pills.
Similar to other opioid analgesics (pain relievers), the most serious health risk from using iso is an overdose. An overdose can cause respiratory failure, which can lead to death. We are asking the public to be aware of this new drug. Like with any opioid use, addiction treatment harm reduction experts recommend people avoid using alone, and carry naloxone, which can be used to reverse an overdose. The potency of isotonitazene may require more than a usual dose of naloxone to restore breathing.
