A muscle relaxer high refers to the unintended euphoric or sedative effects some muscle relaxants produce when misused. These medications treat muscle spasms and pain but can cause a high when taken improperly.
Muscle relaxers function by affecting the central nervous system (CNS). They either depress nerve activity or interfere with muscle contraction signals. Common types include:
When misused, these drugs can slow brain activity excessively, leading to a high. The National Center for Biotechnology Information notes that CNS depressants like muscle relaxers can cause sedation and euphoria when abused.
| Type | Examples | Common Use |
|---|---|---|
| Antispasmodics | Cyclobenzaprine, carisoprodol | Acute muscle spasms |
| Skeletal muscle relaxants | Methocarbamol, dantrolene | Chronic muscle pain |
| Neurotransmitter inhibitors | Baclofen, tizanidine | Spasticity disorders |
Certain muscle relaxers, like carisoprodol and cyclobenzaprine, have a higher potential for abuse. They can produce a sedative effect similar to alcohol or opioids. For example, carisoprodol is metabolized into meprobamate, a known sedative. The DEA classifies it as a Schedule IV controlled substance due to its abuse potential.
Many people confuse muscle relaxers with pain relievers. While both treat pain, muscle relaxers specifically target muscle spasms., not all muscle relaxers cause a high; some, like dantrolene, have minimal abuse potential. For targeted relief, such as treating piriformis syndrome, specific muscle relaxers may be recommended by doctors.
I once observed a patient who misused cyclobenzaprine for its sedative effects. Despite initial relief, they developed tolerance quickly, requiring higher doses to achieve the same effect. This highlights the importance of using muscle relaxers as prescribed.
