Risk assessment

This tablet, sold as XANAX, did not contain the expected benzodiazepine alprazolam, but flualprazolam.

Flualprazolam is an alprazolam derivative and belongs to the group of benzodiazepines. Flualprazolam has never been used as a drug and has hardly been researched. Since flualprazolam is effective in lower doses than alprazolam, there is a risk of overdose if these substances are misdeclared.

According to user reports, flualprazolam is classified as risky: Flualprazolam is a very potent benzodiazepine, but the effect is often perceived by the user as less intense than with other benzodiazepines. Therefore, there is a risk that the user will take an unintentionally high dose that is dangerous to his or her health.

Mixed use with other depressant substances (e.g. codeine, heroin, etc.), dissociatives (e.g. ketamine) and alcohol can lead to unconsciousness and life-threatening respiratory depression.

Medicines bought on the internet are also often misdeclared; always have them tested before use!

Consumption is not advised!

There is hardly any reliable information available on risks, toxicity, side effects and long-term consequences. The following information on flualprazolam is intended only as a guide and is not based on reliable data but on subjective reports from users.

Alert level

Safer Use


Have your substance tested in a drug check if you bought it on the black market or on the internet. Counterfeit blisters may look identical to the original packaging.

Mixed use

Do not mix any depressant substances such as benzodiazepines, alcohol, GHB/GBL or opioids. Risk of unconsciousness or respiratory paralysis!


Feel your way to the dosage and do not rely on dosage information from friends. Various factors such as habituation or dependence can contribute to a greatly increased dosage!


If you do not have the possibility to have substances analyzed, first test a maximum of one third of the pill. Some counterfeit drugs contain a more potent substance than the original.

Wait and see

Wait at least 2 hours after taking the drug. With some drugs, the onset of the intoxicating effect is very slow or it is difficult to perceive.
