Summary
Meclonazepam, also known as (S)-3-methylclonazepam, was unearthed in the 1970s by a research team at Hoffmann-La Roche. This compound falls into the category of benzodiazepine derivatives, sharing structural similarities with clonazepam. Meclonazepam exhibits sedative and anxiolytic properties, mirroring the characteristics of other benzodiazepines. Additionally, it displays anti-parasitic effects against the parasitic worm Schistosoma mansoni.
It’s important to note that Meclonazepam was never utilized as a pharmaceutical medication. Instead, it emerged online as a designer drug.

Meclonazepam use may induce relaxation drowsiness, and alleviate symptoms of anxiety. It is important to note that it can also impair coordination, memory, and judgment. The effects can vary from person to person.
5. Is Meclonazepam safe to use?
The safety of Meclonazepam is a matter of concern. It is not approved for medical use in many countries and is often considered a designer drug. The misuse of benzodiazepines, including Meclonazepam, can lead to various health risks, including addiction and withdrawal symptoms.
6. Can Meclonazepam be detected in drug tests?
Meclonazepam can be detected in specific drug tests, particularly those designed to identify benzodiazepines. However, its inclusion in standard drug panels may vary.
7. Is Meclonazepam prescribed by medical professionals?
Meclonazepam is typically not prescribed by medical professionals. It is more commonly found as a research chemical or a designer drug and is not intended for legitimate medical use.
8. What should I do if I or someone I know is experiencing issues related to Meclonazepam use?
If you or someone you know is struggling with Meclonazepam use or facing adverse effects, seek help from a healthcare professional or an addiction treatment centre. Prompt intervention is essential for your well-being and safety.
