What is bromazolam?

Bromazolam was first described in the 1970s but never marketed. It appeared in the illicit supply around 2016 and became the leading designer benzodiazepine in US drug seizures and overdose deaths by 2022 to 2023.[1]

In June 2024 the UN Commission on Narcotic Drugs placed bromazolam in Schedule IV of the 1971 Convention. The DEA issued a temporary order placing it in Schedule I in March 2026.[1]

Bromazolam effects and how long they last

Bromazolam causes sedation, relaxation, muscle relaxation, and memory loss like alprazolam, with heavy blackouts at higher doses.[1]

Bromazolam side effects and risks

Overdose with opioids: mixed into fentanyl, it causes prolonged sedation that naloxone cannot reverse, raising the risk of death, choking, and injury.[1]

Unknown dose: counterfeit bars contain unpredictable amounts and sometimes fentanyl.[2]

Blackouts and wounds: deep, long sedation leads to amnesia, falls, and pressure injuries.

Warning: Pills sold as Xanax outside a pharmacy are often bromazolam or contain fentanyl. Never use alone, and give naloxone if breathing is slow, even though it will not wake someone from bromazolam alone.

This is not a full list. Combining substances raises the risk of harm, especially when the contents of street drugs are unknown.

Bromazolam overdose: signs and what to do

Overdose causes deep, prolonged sedation, confusion, and coma, and, with opioids or alcohol, stopped breathing. People may wake after naloxone yet remain heavily sedated.[1]

If someone may have overdosed

  • Call 911 if the person is unresponsive, hard to wake, or breathing slowly.
  • For advice when the person is awake and stable, call Poison Help at 1-800-222-1222 (US, free, 24 hours).
  • If opioids could be involved, including pills not from a pharmacy, give naloxone if you have it. Naloxone does not reverse bromazolam, but it will not harm the person.
  • Stay with the person and place them on their side if they are drowsy or vomiting.

Bromazolam withdrawal timeline: symptoms and how long it lasts

Regular use causes benzodiazepine dependence. Withdrawal from designer benzodiazepines can be severe and has caused seizures.[1]

  1. Day 1 to 3Symptoms beginRebound anxiety, insomnia, restlessness, sweating, and tremor.
  2. Weeks 1 to 4Acute withdrawalPanic, irritability, muscle pain, nausea, sensitivity to light and sound, and in severe cases seizures or delirium.
  3. MonthsProtracted symptoms in some peopleA minority have lingering anxiety, poor sleep, low mood, or tingling that can last weeks to more than 12 months.

Warning: Stopping regular bromazolam use suddenly can cause seizures. Seek medical help to taper, usually with a prescribed benzodiazepine.

People exposed to benzo dope may need treatment for both opioid and benzodiazepine withdrawal.
