Etizolam is not licensed for use in the UK, but it is a licensed drugs in other countries prescribed to treat sleep problems and anxiety among other health issues.

How it’s taken

Most commonly swallowed.

Injecting is almost always the riskiest way of taking drugs and is strongly discouraged.


There is no guarantee of the accuracy of the contents marked on packets, as etizolam is not prescribed in the UK. Generally sold as tablets ranging from 0.5 mg to 2 mg. Etizolam is stronger than diazepam (Valium) – a 1 mg etizolam tablet is equivalent to a 10 mg diazepam tablet (these doses should not be taken as a recommendation).

Etizolam is short-acting benzodiazepine (the effects can wear off quickly). The effects can appear within 30–60 minutes, and last between 6–8 hours, depending on amount taken and individual metabolism.

General information on dosing.


Benzodiazepines can cause drowsiness and long periods of sleep. They slow down your heart rate and breathing. People taking them can experience a ‘floating’ sensation as well as a warm, calm and relaxed feeling. Other effects can include lack of coordination, slowed speech, blackouts, short-term memory loss, reduced mental alertness and anxiety.

Benzodiazepines can also reduce anxiety and therefore impair your judgement of danger. This makes people care less, and can result in risky behaviour.

However, some people taking benzodiazepines, particularly at higher doses, can experience increased anxiety, seizures or ‘fitting’, aggression and other negative symptoms.

Withdrawal symptoms can happen even after short periods of use. Avoid taking for more than 4 weeks. With prolonged use, withdrawal effects can be severe and may include headaches, seizures (fits) nausea, extreme anxiety, depression, paranoia and delusions (very strong beliefs that other people don’t share). The severity of the symptoms will vary depending on the amount of drug used but symptoms will ease with time. During this time, to help the body recover, a healthy diet, fresh air, light exercise can help. Try to resist taking more of the drug, or other drugs (including alcohol) to deal with the withdrawal symptoms.

Stopping after longer term use requires a steady reduction of dose (tapering) and support: stopping suddenly and completely can be fatal. Your GP or local drug service can help with this.

  • Use can lead to memory loss
  • Tolerance develops quickly which can lead to people using more over time, increasing the risk of dependence and overdose
  • Withdrawal symptoms can happen after even short periods of time
  • Increased risk of overdose if mixed with alcohol, opiates (like heroin) or opioids (like methadone)or other depressant drugs

Harm reduction

If you choose to take etizolam then the following steps can help to reduce harm.
  • Avoid mixing benzos with alcohol, prescription drugs and other drugs, especially other depressants/downers such as alcohol, diazepam and gabapentin and opiates or opioids such as heroin and methadone. All of these drugs can depress breathing resulting in a serious risk of death if mixed.
  • Call 999 and ask for an ambulance if you see the signs of an overdose: confusion, unconsciousness (won’t wake with a shout or a shake), severe nausea and vomiting, fitting, difficulty breathing, snoring/raspy breathing, blue/pale tingeing of knees, hands and lips, slow or erratic pulse (heartbeat), pale, cold and clammy skin.
  • Avoid taking benzos alone and stay with friends in case you experience negative effects.
  • Sleep on your side to avoid choking in your sleep if you throw up.
  • Strength can vary, even between pills from the same batch/packet if unlicensed/not prescribed, or pills which look the same. Start with a small test dose and wait at least 2 hours before re-dosing.
  • It is easy to build a tolerance to benzodiazepines.
  • Withdrawal symptoms can happen even after short periods of use. Avoid taking every day and take regular breaks from use.
  • Avoid taking other drugs or more benzodiazepines to deal with withdrawal symptoms.
  • If symptoms become distressing seek medical help and in an emergency call 999.
