Muscle relaxers can be helpful when they are used exactly as prescribed for short-term muscle spasms, back pain, or injury-related discomfort. But because many muscle relaxers affect the central nervous system, they can also cause drowsiness, sedation, impaired coordination, and dangerous interactions with alcohol, opioids, benzodiazepines, or other depressants.
So, are muscle relaxers addictive? The answer is: some muscle relaxers carry a higher risk than others, and misuse can become dangerous quickly. Carisoprodol, sold under the brand name Soma, is one of the clearest examples because it has documented risks of abuse, dependence, withdrawal, and diversion. The FDA label for Soma states that carisoprodol has been subject to abuse, dependence, withdrawal, misuse, and criminal diversion.
For people with a history of substance use, the risk may be higher. Muscle relaxers may seem “safer” than opioids or benzodiazepines because they are commonly prescribed for pain, but that does not mean they are harmless.
What Are Muscle Relaxers?
Muscle relaxers are medications used to reduce muscle spasms, stiffness, or pain. They are often prescribed after injuries, surgeries, or episodes of acute back or neck pain. Common muscle relaxers include:
| Medication | Common Brand Name | Addiction / Misuse Concern |
|---|---|---|
| Carisoprodol | Soma | Higher concern; Schedule IV controlled substance |
| Cyclobenzaprine | Flexeril, Amrix | Not federally controlled, but can be misused |
| Methocarbamol | Robaxin | Lower abuse potential, but still sedating |
| Baclofen | Lioresal | Can cause dependence and withdrawal if stopped suddenly |
| Tizanidine | Zanaflex | Can cause sedation and withdrawal symptoms |
Not every muscle relaxer works the same way. Some are more sedating than others. Some are prescribed for short-term injuries, while others may be used for neurological conditions involving muscle spasticity. The key issue is that many of them slow down activity in the brain and nervous system, which can become risky when taken in larger doses, taken more often than prescribed, or mixed with other substances.
Why Some Muscle Relaxers Can Be Addictive
Muscle relaxers can become habit-forming when a person begins using them for reasons other than the original medical purpose. This may include taking them to relax, sleep, numb emotions, intensify the effects of other drugs, or avoid withdrawal symptoms.
Carisoprodol is especially concerning because it is metabolized into meprobamate, a sedative medication with known abuse potential. According to StatPearls, carisoprodol is a Schedule IV controlled substance, and dependence, withdrawal, and misuse have been reported with prolonged use, especially in people with a history of addiction or when combined with other drugs that have misuse potential.
The Drug Enforcement Administration also notes that continuous carisoprodol abuse can cause tolerance and dependence, and that it is often combined with substances like opioids and benzodiazepines, increasing the risk of tolerance, dependence, and withdrawal.
Signs of Muscle Relaxer Misuse
Muscle relaxer misuse does not always look obvious at first. A person may start by taking an extra dose during a painful day, using an old prescription, or combining the medication with alcohol “just to relax.” Over time, misuse can become more frequent and harder to control.
Possible signs of muscle relaxer misuse include:
- Taking more than prescribed
- Running out of medication early
- Using someone else’s prescription
- Mixing muscle relaxers with alcohol, opioids, benzodiazepines, or sleep medications
- Feeling unable to relax or sleep without the medication
- Doctor shopping or seeking multiple prescriptions
- Using muscle relaxers to feel sedated, numb, or high
- Memory problems, confusion, slurred speech, or poor coordination
- Withdrawal symptoms when trying to stop
A person does not have to “look addicted” to be in danger. Sedating medications can impair judgment, breathing, coordination, and decision-making, especially when combined with other substances.
Can You Withdraw From Muscle Relaxers?
Yes, withdrawal can happen with certain muscle relaxers, especially after prolonged use, high-dose use, or abrupt stopping. Carisoprodol withdrawal has been reported in the medical literature and can include symptoms such as anxiety, insomnia, tremors, nausea, muscle twitching, hallucinations, and in severe cases, delirium. One published case study described severe confusion and hallucinations after abrupt discontinuation of heavy carisoprodol use.
Withdrawal risk depends on the medication, dose, duration of use, medical history, and whether other substances are involved. Anyone who has been taking muscle relaxers regularly should speak with a medical professional before stopping suddenly.
Why Mixing Muscle Relaxers With Alcohol or Other Drugs Is Dangerous
One of the biggest risks with muscle relaxers is mixing them with other central nervous system depressants. This includes alcohol, opioids, benzodiazepines, sleep medications, and some anxiety medications.
Cyclobenzaprine labeling warns that alcohol can increase certain side effects of the medication, and FDA labeling for Flexeril states that it may impair mental or physical abilities, especially when used with alcohol or other CNS depressants.
Soma’s FDA label also warns that the sedative effects of carisoprodol and other CNS depressants, including alcohol, benzodiazepines, opioids, and tricyclic antidepressants, may be additive.
That means the effects can stack. A dose that might seem manageable alone can become dangerous when combined with another depressant. Risks may include:
- Extreme drowsiness
- Blackouts
- Falls or accidents
- Slowed breathing
- Loss of consciousness
- Overdose
- Death
This is especially important for people with opioid use disorder, alcohol use disorder, benzodiazepine dependence, or a history of polysubstance use.
Are Muscle Relaxers Safer Than Opioids?
Muscle relaxers are different from opioids, but “different” does not always mean “safe.” They may be prescribed instead of opioids in some cases, but they still carry risks. Some muscle relaxers can cause sedation, dependence, withdrawal, and dangerous drug interactions.
A 2024 systematic review on long-term skeletal muscle relaxant use found that long-term use may only be beneficial for certain conditions, and clinicians should consider deprescribing when pain-related goals are not being met.
In other words, these medications are often intended for short-term or carefully monitored use. If someone finds themselves relying on muscle relaxers emotionally, taking them outside prescription directions, or combining them with other substances, it may be time to ask for help.
When Muscle Relaxer Use Becomes a Substance Use Concern
Muscle relaxer use may be a sign of a substance use problem when the medication is no longer being used only for physical symptoms. For example, a person may begin using muscle relaxers to escape stress, anxiety, trauma, insomnia, grief, or cravings.
Warning signs may include:
- “Needing” the medication to get through the day
- Feeling panicked when the prescription runs low
- Taking muscle relaxers with alcohol or other drugs
- Hiding use from family or providers
- Continuing use despite consequences
- Failed attempts to stop or cut back
- Cravings or compulsive use
Substance use disorders are medical conditions, not moral failures. If muscle relaxers have become part of a larger pattern of drug or alcohol misuse, support is available.
Treatment for Muscle Relaxer Misuse
Treatment depends on the person’s symptoms, substances involved, medical history, and level of dependence. Some people may need medical detox or a supervised taper, especially if they have been using high doses, mixing substances, or experiencing withdrawal symptoms.
After stabilization, treatment may include:
- Medical and psychiatric assessment
- Individual therapy
- Group therapy
- Relapse prevention planning
- Trauma-informed care
- Medication management when appropriate
- Support for co-occurring anxiety, depression, trauma, or chronic pain
- Family education and recovery planning

Frequently Asked Questions About Muscle Relaxer Dependency
Are muscle relaxers addictive?
Yes, some muscle relaxers can be addictive, especially when they are taken in higher doses, used longer than prescribed, or mixed with alcohol, opioids, benzodiazepines, or other sedating substances. Carisoprodol (Soma) is one of the muscle relaxers most closely associated with misuse, dependence, and withdrawal.
Can you get addicted to muscle relaxers?
Yes. A person can become addicted to muscle relaxers if they begin using them for reasons other than pain or muscle spasms, such as to feel relaxed, numb, sleepy, or high. Addiction risk may be higher for people with a history of substance use or those combining muscle relaxers with other drugs.
Can you become addicted to muscle relaxers even with a prescription?
Yes. Having a prescription does not eliminate the risk of addiction. Taking larger doses than prescribed, using the medication longer than recommended, or relying on it emotionally can increase the risk of misuse, dependence, and addiction.
Can muscle relaxers be addictive if you only use them at night?
They can be, depending on the medication, dose, frequency, and reason for use. Taking a muscle relaxer at night for a short period under medical supervision is different from feeling unable to sleep or relax without it. If a person becomes dependent on the medication to function or rest, it may be a sign of a developing problem.
Are all muscle relaxers addictive?
No. Not all muscle relaxers have the same potential for misuse or dependence. Some carry a higher risk than others, but any muscle relaxer can become problematic if it is taken improperly, used recreationally, or combined with alcohol or other substances.
What muscle relaxer is considered the most addictive?
Carisoprodol (Soma) is generally considered one of the muscle relaxers with the highest potential for misuse and dependence. Because it is metabolized into meprobamate, a sedative with abuse potential, it carries greater addiction risks than many other muscle relaxers.
What are the signs of muscle relaxer abuse?
Common signs of muscle relaxer misuse include taking more than prescribed, running out of medication early, using someone else’s prescription, mixing the medication with alcohol or drugs, experiencing cravings, hiding use from loved ones, or feeling unable to function without the medication.
Can you overdose on muscle relaxers?
Yes. An overdose can occur, especially when muscle relaxers are combined with alcohol, opioids, benzodiazepines, sleep medications, or other central nervous system depressants. Symptoms may include extreme drowsiness, confusion, slowed breathing, loss of consciousness, or unresponsiveness.
