Key Takeaways:
- If you’re wondering are muscle relaxers addictive, the answer is that some can be habit-forming, but the risk varies widely by medication.
- Physical dependence, tolerance, and addiction aren’t the same thing.
- Carisoprodol (Soma) is a Schedule IV controlled substance with a recognized risk of misuse and dependence.
- Even lower-risk muscle relaxers can cause problems if misused or stopped too quickly.
- If you’re struggling to control your muscle relaxer use, professional support can help you decide what to do next.
Some muscle relaxers can be addictive or habit-forming, although the risk isn’t the same with every medication. Some, like carisoprodol (Soma), have a recognized potential for misuse and dependence. Others carry considerably less risk.
And if you’ve been taking a muscle relaxer regularly and are starting to wonder whether you rely on it more than you used to, that doesn’t automatically mean you have an addiction. Physical dependence and addiction are different things. Understanding what’s actually happening can help you figure out what to do next without jumping to the worst conclusion.
What Muscle Relaxers Are and How They Affect the Brain and Body
“Muscle relaxer” is actually a pretty broad term. Doctors may prescribe these medications for painful muscle spasms after an injury or for conditions that cause ongoing muscle tightness. And despite the name, many of them don’t simply switch off a tight muscle. They work by changing activity in the brain and nervous system.
That’s also why some muscle relaxers can become a problem. Depending on the medication, you might feel sleepy or unusually relaxed. Some can also change the way you experience pain or discomfort. For some people, those effects can become appealing for reasons unrelated to the original muscle pain.
Not all muscle relaxers work the same way, though. Some are mainly used for short-term muscle spasms, while others are prescribed for muscle tightness related to conditions that affect the brain or spinal cord. Those differences matter when we start talking about dependence and addiction because the risks can vary quite a bit from one medication to another.
Dependence vs. Tolerance vs. Addiction: The Key Differences
These terms get used a lot interchangeably, but they don’t mean the same thing. You can develop tolerance or physical dependence while taking a medication as prescribed. Addiction involves something different.
- Tolerance means your body has adapted to the medication, so the same dose may not have the effect it once did.
- Physical dependence means your body has gotten used to having the medication around. If you suddenly stop taking it, you may experience withdrawal symptoms.
- Addiction involves continuing to use a drug despite harmful consequences or having a hard time controlling your use.
That distinction can be reassuring if you’ve noticed changes after taking a muscle relaxer for a while. At the same time, if you’re taking more than prescribed, running out early, or finding that it’s becoming harder to control how you use it, those are worth paying attention to.
Which Muscle Relaxers Carry the Highest Addiction Risk?
Not all muscle relaxers carry the same risk of misuse or dependence. Carisoprodol (Soma) stands out because it is federally controlled and its prescribing information specifically warns about abuse, dependence, and withdrawal. Diazepam (Valium), which can also be used for muscle spasms, is a benzodiazepine and a Schedule IV controlled substance as well.
For the others, “not controlled” doesn’t necessarily mean “no risk.” Some can still cause physical dependence or withdrawal problems, particularly after regular or prolonged use.
| Medication | Type | Misuse/Dependence Concern | Federal Controlled Substance? |
|---|---|---|---|
| Carisoprodol (Soma) | Skeletal muscle relaxant | Greater documented concern for misuse and dependence | Yes, Schedule IV |
| Diazepam (Valium) | Benzodiazepine also used as a muscle relaxant | Known misuse, dependence, and addiction risk | Yes, Schedule IV |
| Cyclobenzaprine (Flexeril) | Skeletal muscle relaxant | Lower addiction concern; withdrawal-like symptoms can rarely occur after prolonged use | No |
| Tizanidine | Antispasticity medication | Not controlled, but physical dependence and rebound withdrawal have been reported | No |
| Baclofen | Antispasticity medication | Not typically treated as an addictive drug, but abrupt withdrawal can be dangerous | No |
| Methocarbamol, metaxalone, orphenadrine | Skeletal muscle relaxants | Generally lower misuse concern than carisoprodol or diazepam | No |
Carisoprodol deserves particular attention because its prescribing information warns about misuse, dependence, and withdrawal. Baclofen presents a different concern. It isn’t typically considered addictive, but suddenly stopping it can cause serious withdrawal symptoms, including hallucinations and seizures. That distinction is exactly why “addictive” isn’t a useful catch-all for every risk associated with muscle relaxers.
Do Muscle Relaxers Get You High? What Misuse Looks Like
Some muscle relaxers can cause effects that people may find appealing beyond pain relief. Depending on the medication and dose, that might mean feeling unusually relaxed or sedated. Taking a muscle relaxer specifically for those effects rather than for the reason it was prescribed can be a form of misuse.
Misuse can also look less obvious. Maybe you’ve started taking an extra dose because the usual amount doesn’t seem to work anymore. You might find yourself taking it when your muscles aren’t bothering you or thinking about your next dose more than you used to.
None of those things automatically tells you that you have an addiction. But if the way you’re using your medication has started to change, it’s worth paying attention to that now rather than waiting for it to become a bigger problem.
Signs and Symptoms of Muscle Relaxer Addiction
Physical Signs
Your body may start giving you clues that something has changed. Maybe the dose that used to work doesn’t seem to do much anymore, or you feel lousy when you skip it or try to cut back. You might also notice that you’re much more tired or foggy when you take it than you used to be.
Behavioral and Psychological Signs
Sometimes the changes in your behavior are easier to spot. You may find yourself taking the medication more often than prescribed or using it even when you’re no longer having muscle pain. You might worry about running out, try to get refills early, or keep using it even though it’s starting to cause problems at home or work.
One or two of these signs by themselves don’t necessarily mean you have an addiction. The bigger concern is a pattern of losing control over your use or continuing despite negative consequences.
Muscle Relaxer Withdrawal Symptoms and Timeline
Withdrawal from muscle relaxers can look very different depending on which medication you’ve been taking and how your body has adapted to it. Some people may feel uncomfortable when they stop, while withdrawal from certain medications can become medically serious.
That’s why suddenly stopping a muscle relaxer after taking it regularly isn’t always a good idea. If you’re worried that you’ve become dependent on one, talk with your prescriber before trying to quit on your own.
Common Withdrawal Symptoms
Withdrawal doesn’t look the same with every muscle relaxer. You may notice that you feel anxious or restless, have trouble sleeping, or feel physically uncomfortable when you miss a dose. With some medications, the muscle spasms or tightness the drug was treating can also return or temporarily get worse.
When Withdrawal Becomes Dangerous
Some muscle relaxers need more caution than others. Abruptly stopping baclofen, for example, can lead to serious withdrawal symptoms, including hallucinations and seizures. Carisoprodol can also cause withdrawal after prolonged use.
If you’ve been taking a muscle relaxer regularly, especially at a higher dose or for a long time, don’t assume you should simply stop taking it. A medical professional can determine whether you need to taper your dose and how to do that safely.
General Withdrawal Timeline by Phase
No single withdrawal timeline applies to every muscle relaxer. The specific medication matters much more than a generic day-by-day schedule. Symptoms may begin after the drug level starts dropping, become more noticeable over the following days, and gradually improve as your body adjusts.
Overdose Risks and Dangerous Drug Combinations
Taking too much of a muscle relaxer can be dangerous, especially with medications that cause significant sedation. Depending on the drug, an overdose can cause severe drowsiness, confusion, loss of consciousness, or problems with breathing.
The risk increases when you take muscle relaxers with other substances that slow the central nervous system. This is one reason it’s important that your prescriber knows about everything you’re taking, including medications prescribed by someone else.
Mixing Muscle Relaxers With Alcohol, Opioids, or Benzodiazepines
Alcohol, opioids, and benzodiazepines can all add to the sedating effects of certain muscle relaxers. Carisoprodol’s current prescribing information specifically warns that its sedative effects can be increased when it’s taken with these substances. Baclofen carries a similar warning about alcohol and other central nervous system depressants.
Combining opioids with muscle relaxants can be particularly dangerous because of the potential for increased sedation and respiratory depression. Current FDA opioid labeling warns that using opioids with other central nervous system depressants, including muscle relaxants, can lead to profound sedation, respiratory depression, coma, and death.
If someone is difficult to wake, has very slow or difficult breathing, or loses consciousness after taking these medications, call 911 immediately.
Treatment for Muscle Relaxer Addiction
If you’re having trouble controlling your muscle relaxer use, treatment can help you figure out how to stop safely. The approach will depend on which medication you’ve been taking and whether you’ve developed physical dependence.
Some people may need medically supervised withdrawal or a gradual taper before beginning addiction treatment. Safe & Sound Treatment offers medical detox for people who need help managing withdrawal, along with residential and outpatient treatment options. Once you’re medically stable, treatment can help you address the reasons your medication use became a problem and build a plan for moving forward.
Depending on what you need, treatment at Safe & Sound may include:
- Medical detox: Medical supervision and support during withdrawal when needed.
- Residential treatment: Live-in care with a structured treatment schedule and around-the-clock support.
- Partial hospitalization (PHP): More structured outpatient care with full treatment days while you continue living off-site.
- Intensive outpatient treatment (IOP): Regular treatment sessions with more room for work, school, and everyday responsibilities.
- Outpatient treatment: Ongoing therapy and support with a less intensive schedule.
- Individual and group therapy: A chance to work through your own concerns while also learning alongside others in recovery.
- Dual diagnosis treatment: Support when substance use and a mental health condition are happening at the same time.
How to Help a Loved One Who May Be Misusing Muscle Relaxers
If you’re worried about someone you love, start with what you’ve actually noticed rather than trying to convince them they have an addiction. Maybe they’re running out of medication earlier than they used to, or you’ve noticed that the way they take it has changed. They may just seem different lately, too.
You can encourage them to talk with their doctor or an addiction treatment professional about what’s going on. And if they’ve been taking a muscle relaxer regularly, don’t push them to suddenly stop. Depending on the medication, withdrawal may need medical supervision.

Frequently Asked Questions
Can you get addicted to muscle relaxers if you take them as prescribed?
It’s possible to develop physical dependence on some muscle relaxers even when you take them as prescribed. That isn’t necessarily the same as addiction. The risk depends on the medication and how long you’ve been taking it.
Is Soma more addictive than other muscle relaxers?
Carisoprodol (Soma) has a well-documented potential for misuse and dependence and is classified as a Schedule IV controlled substance. Many commonly prescribed muscle relaxers are not federally controlled substances.
Can you stop taking muscle relaxers suddenly?
It depends on the medication. Some muscle relaxers can cause withdrawal symptoms if they’re stopped abruptly after regular use, and withdrawal from medications such as baclofen can become serious. Talk with your prescriber before stopping a muscle relaxer you’ve been taking regularly.
Can muscle relaxer addiction be treated?
Yes. Treatment can address compulsive medication use and the issues that may be contributing to it. If physical dependence is involved, medical support may be needed first to safely reduce or stop the medication.
