Are Muscle Relaxers Addictive? Risks and Side Effects

Written by Soberman's Contributor | August 21, 2025 at 2:30 PM

Muscle relaxers are commonly prescribed medications used to relieve muscle pain and spasms. While they can be highly effective for short-term treatment, many people wonder: Are muscle relaxers addictive? 

This article explores the effects of muscle relaxers, their potential for addiction, common side effects, and available treatment options. Whether you or a loved one is using prescription muscle relaxers, understanding these factors is crucial for safe and effective use. 

Questions Answered: 

  • How Do Muscle Relaxers Work? 
  • Are Muscle Relaxers Addictive? 
  • How Common is Muscle Relaxer Addiction? 

 

How Do Muscle Relaxers Work? 

Muscle relaxers, also known as skeletal muscle relaxants, are prescription drugs designed to reduce muscle spasms, stiffness, and pain. They work by affecting the central nervous system to relax muscles and improve mobility.  

There are two main types of muscle relaxers: 

Centrally-acting muscle relaxers – These affect the central nervous system (CNS) to reduce muscle tone and promote relaxation. 

Direct-acting muscle relaxers – These work directly on the muscle tissue rather than the brain or spinal cord. 

 

Common prescription muscle relaxers include: 

  • Carisoprodol (Soma) 
  • Cyclobenzaprine (Flexeril) 
  • Methocarbamol (Robaxin) 
  • Diazepam (Valium) – also classified as a benzodiazepine 

Some of these, like carisoprodol Soma, are classified as controlled substances due to their potential for abuse and addiction. 

Muscle relaxers primarily act on the central nervous system, slowing down nerve activity to reduce muscle tension. This sedative effect helps relieve muscle spasms and the associated muscle pain. However, because of this central nervous system depression, these drugs can cause drowsiness, dizziness, and impaired coordination. 

 

Muscle Relaxers Side Effects 

Like any medication, muscle relaxers come with potential side effects. Common side effects include: 

  • Drowsiness and fatigue 
  • Dizziness or lightheadedness 
  • Dry mouth 
  • Headache 
  • Nausea 

 

More serious side effects, though less common, can include: 

  • Changes in blood pressure (either high or low) 
  • Confusion or hallucinations 
  • Allergic reactions 
  • Respiratory depression in rare cases 

Long-term use of muscle relaxers can increase the risk of these side effects and may lead to tolerance, where a higher dose is needed to achieve the same effect.

Recovery begins with a choice. 

 

Are Muscle Relaxers Addictive? 

Muscle relaxers can be addictive, especially when used for extended periods or at a higher dose than prescribed. The risk varies depending on the type of muscle relaxer and the patient’s history. 

Central Nervous System Depression 

Many skeletal muscle relaxants produce a sedative effect. They slow down brain activity, leading to central nervous system depression. In high doses or when combined with other controlled substances, like opioids or alcohol, they can trigger dangerous outcomes, including respiratory failure or overdose. 

Carisoprodol (Soma) and Addiction 

Among all muscle relaxers, carisoprodol (Soma) is considered the most addictive. It’s classified as a Schedule IV controlled substance in the United States. It metabolizes into meprobamate, a drug with tranquilizer-like effects, making it highly prone to misuse. 

Over time, users can develop an addiction to muscle relaxants like Soma, especially when chasing the euphoric or sedative effects. 

 

How Common is Muscle Relaxer Addiction? 

Addiction to muscle relaxers is a growing concern, especially with certain medications like carisoprodol Soma. While not everyone who takes these drugs becomes addicted, the risk increases with prolonged use, higher doses, and misuse. 

Statistics show that misuse of prescription muscle relaxers contributes to thousands of emergency room visits annually. Among the types of muscle relaxers, carisoprodol and benzodiazepines like diazepam carry the highest risk of addiction because of their sedative and euphoric effects. 

 

Signs and Symptoms of Muscle Relaxer Addiction 

Recognizing early signs of misuse is critical for getting help. Symptoms of addiction to muscle relaxers may include: 

  • Taking the medication in larger amounts or for longer than prescribed 
  • Cravings and preoccupation with obtaining the drug 
  • Withdrawal symptoms such as anxiety, irritability, insomnia, and muscle pain occur when not using the drug 
  • Developing tolerance, requiring a higher dose for relief 
  • Neglecting responsibilities or social activities

Risks and Dangers of Muscle Relaxer Abuse 

Abusing muscle relaxers can lead to serious health risks. The central nervous system depression caused by these drugs can slow breathing and heart rate, especially when combined with alcohol or other prescription medications that have sedative effects. This increases the risk of overdose, coma, or even death. 

Long-term misuse can also cause cognitive impairment, memory problems, and emotional instability. Additionally, abrupt discontinuation after prolonged use can trigger severe withdrawal symptoms. 

 

Preventing Muscle Relaxer Addiction 

To reduce the risk of addiction, muscle relaxers should be used strictly as prescribed. Here are some key tips: 

  • Use muscle relaxers only for short-term treatment (usually 2-3 weeks) unless otherwise directed by a healthcare provider 
  • Avoid combining with alcohol or other sedative drugs 
  • Inform your doctor about any history of substance abuse 
  • Follow dosage instructions carefully and never increase the dose on your own 
  • If muscle relaxers are needed for longer periods, your doctor may monitor you closely or suggest alternative treatments. 

 

Treatment Options for Muscle Relaxer Addiction 

Addiction treatment programs can guide you through detox, recovery, and relapse prevention.  

 

Addiction treatment may involve: 

  • Medical evaluation and detoxification under supervision 
  • Counseling and behavioral therapy 
  • Support groups and rehabilitation programs 
  • Medication-assisted treatment, if necessary 

Getting the right treatment options early can prevent long-term health problems and improve quality of life.
