Mixing
For best safety practice, don't mix this drug with other depressants.
Why: respiratory depression. PsychonautWiki says:
- “Respiratory depression (also known as hypoventilation) can be described as a reduced urge to breathe that can be fatal depending on its intensity.” (PsychonautWiki, Respiratory depression, revision 150612)
- “... otherwise safe dosages of these compounds can become fatal when combined with even small amounts of other classes of depressant. For example, benzodiazepines combined with opioids are an extremely common cause of fatal respiratory depression. It is therefore strongly discouraged to combine these depressants at any dosage range.” (PsychonautWiki, Respiratory depression, revision 150612)
- “The most common cause of substance-related deaths is the combination of depressants (such as opiates, benzodiazepines, or alcohol) with other depressants.” (PsychonautWiki, Responsible drug use, revision 168206)
- “This combination potentiates the muscle relaxation, amnesia, sedation, and respiratory depression caused by one another. At higher doses, it can lead to a sudden, unexpected loss of consciousness along with a dangerous amount of depressed respiration.” (PsychonautWiki, dangerous interactions table, "Depressants" row, revision 156847)

Other documented combinations
- Depressants (1,4-Butanediol, 2-methyl-2-butanol, alcohol, barbiturates, GHB/GBL, methaqualone, opioids) - This combination can result in dangerous or even fatal levels of respiratory depression. These substances potentiate the muscle relaxation, sedation and amnesia caused by one another and can lead to unexpected loss of consciousness at high doses. There is also an increased risk of vomiting during unconsciousness and death from the resulting suffocation. If this occurs, users should attempt to fall asleep in the recovery position or have a friend move them into it. PW⚠ PsychonautWiki lists this combination without a danger rating.
- Dissociatives - This combination can result in an increased risk of vomiting during unconsciousness and death from the resulting suffocation. If this occurs, users should attempt to fall asleep in the recovery position or have a friend move them into it. PW⚠ PsychonautWiki lists this combination without a danger rating.
- Stimulants - It is dangerous to combine benzodiazepines with stimulants due to the risk of excessive intoxication. Stimulants decrease the sedative effect of benzodiazepines, which is the main factor most people consider when determining their level of intoxication. Once the stimulant wears off, the effects of benzodiazepines will be significantly increased, leading to intensified disinhibition as well as other effects. If combined, one should strictly limit themselves to only dosing a certain amount of benzodiazepines per hour. This combination can also potentially result in severe dehydration if hydration is not monitored. PW⚠ PsychonautWiki lists this combination without a danger rating.

Caution
Risks and toxicity
Pyrazolam likely has a low toxicity relative to dose. However, it is potentially lethal when mixed with depressants like alcohol or opioids.[7] PW
It is strongly recommended that one use harm reduction practices when using this substance. PW
Tolerance and addiction potential
Pyrazolam is extremely physically and psychologically addictive. PW
Tolerance will develop to the sedative-hypnotic effects within a couple of days of continuous use. After cessation, the tolerance returns to baseline in 7 - 14 days. However, in certain cases this may take significantly longer in a manner which is proportional to the duration and intensity of one's long-term usage. PW
Withdrawal symptoms or rebound symptoms may occur after ceasing usage abruptly following a few weeks or longer of steady dosing, and may necessitate a gradual dose reduction. For more information on tapering from benzodiazepines in a controlled manner, please see this guide. PW
Benzodiazepine discontinuation is notoriously difficult; it is potentially life-threatening for individuals using regularly to discontinue use without tapering their dose over a period of weeks. There is an increased risk of hypertension, seizures, and death. Drugs which lower the seizure threshold such as tramadol should be avoided during withdrawal.[8] PW
Pyrazolam presents cross-tolerance with all benzodiazepines, meaning that after its consumption all benzodiazepines will have a reduced effect. PW
Overdose
Benzodiazepine overdose may occur when a benzodiazepine is taken in extremely heavy quantities or concurrently with other depressants. This is particularly dangerous with other GABAergic depressants such as barbiturates and alcohol since they work in a similar fashion, but bind to distinct allosteric sites on the GABAA receptor, thus their effects potentiate one another. Benzodiazepines increase the frequency in which the chlorine ion pore opens on the GABAA receptor while barbiturates increase the duration in which they are open, meaning when both are consumed, the ion pore will open more frequently and stay open longer. Benzodiazepine overdose is a medical emergency that may lead to a coma, permanent brain injury or death if not treated promptly and properly.[9] PW
Symptoms of a benzodiazepine overdose may include severe thought deceleration, slurred speech, confusion, delusions, respiratory depression, coma or death. Benzodiazepine overdoses may be treated effectively in a hospital environment, with generally favorable outcomes. Benzodiazepine overdoses are sometimes treated with flumazenil, a GABAA antagonist, however care is primarily supportive in nature.[10] PW
Dangerous interactions
Although many drugs are safe on their own, they can become dangerous and even life-threatening when combined with other substances. The list below contains some common potentially dangerous combinations, but may not include all of them. Certain combinations may be safe in low doses of each but still increase the potential risk of death. Independent research should always be done to ensure that a combination of two or more substances is safe before consumption. PW
Testing
Effects
Overview
Pyrazolam is a novel depressant substance of the benzodiazepine class. PW
RC benzodiazepine discovered by Hoffman-LaRoche in the 1970s. Came to the RC market in the early 2010s. At lower doses it is mainly an anxiolytic compound, yet at higher doses can be quite sedating, hypnotic, amnesic, and can cause loss of inhibitions. Structurally similar to Alprazolam, Bromazepam, and Triazolam. Is 12x as potent as Diazepam. TS
Pyrazolam (SH-I-04) is a benzodiazepine derivative originally developed by a team led by Leo Sternbach at Hoffman-La Roche in the 1970s. It has since been "rediscovered" and sold as a designer drug since 2012.[1–5] WP
Pyrazolam has structural similarities to alprazolam and bromazolam. Unlike other benzodiazepines, pyrazolam does not appear to undergo metabolism, instead being excreted unchanged in the urine.[3]
History
Legal status
- Pyrazolam is not explicitly prohibited in most parts of the world, meaning it exists in a legal grey area. This means that it is not known to be specifically illegal, people may still be charged for its possession under certain circumstances such as under analogue laws and with intent to sell or consume. PW
- Canada: All benzodiazepines are listed in Schedule IV.[11] PW
- Germany: Pyrazolam is controlled under the NpSG (New Psychoactive Substances Act) as of July 18, 2019. Production and import with the aim to place it on the market, administration to another person and trading is punishable. Possession is illegal but not penalized.[12]
[13] [14] PW - Russia: Pyrazolam is a Schedule III controlled substance since 2017.[15] PW
- Sweden: Pyrazolam is a controlled substance.[16] PW
- Switzerland: Pyrazolam is a controlled substance specifically named under Verzeichnis E.[17] PW
- Turkey: Pyrazolam is a classed as drug and is illegal to possess, produce, supply, or import.[18] PW
- United Kingdom: Pyrazolam is a Class C controlled substance as of May 31, 2017. It is illegal to possess, produce or supply.[19] PW
United kingdom
In the UK, pyrazolam has been classified as a Class C drug by section 5 of the May 2017 amendment to The Misuse of Drugs Act 1971 along with several other designer benzodiazepine drugs.[20] WP
United states
Unscheduled at the federal level. WP
Alabama made Pyrazolam a schedule I substance on March 18th, 2014.[21] WP
