What Robaxin is
Robaxin is methocarbamol, a centrally acting skeletal muscle relaxant for short-term relief of painful muscle spasms. It is not an opioid and not a narcotic.
It is not a controlled substance in the United States. It is still a central nervous system depressant and can be misused, particularly alongside other sedatives.
It usually starts working in about 30 minutes and lasts four to six hours, staying in the body for roughly five to ten hours, longer with liver or kidney impairment.

Robaxin isn’t classified as highly addictive, but misuse (such as taking larger or more frequent doses, or mixing with alcohol/other sedatives) can lead to dependence and harm. If you’re noticing increasing use, it’s a good time to talk with a professional.
Drowsiness, dizziness, headache, and blurry vision are common. Avoid driving or operating machinery until you know how Robaxin affects you. Seek help urgently for extreme sleepiness, fainting, or trouble breathing, especially if other depressants were used.
It’s best to avoid alcohol. Combining Robaxin with alcohol, opioids, or benzodiazepines can intensify sedation and depress breathing. If you’ve already been mixing, call us for confidential guidance on staying safe.
You’re not alone. We can help you assess risk and plan next steps, often starting with a safe, medically supported taper or detox and then ongoing treatment that fits your life (residential, IOP, or outpatient).

What Is Robaxin (Methocarbamol)?
Robaxin is the brand name for methocarbamol, a muscle relaxant often prescribed for muscle spasms, tension, or injuries. It works by calming the central nervous system and blocking pain signals to the brain. While not a narcotic, Robaxin may cause side effects like drowsiness and dizziness.
Doctors sometimes prescribe it alongside physical therapy and rest. In certain cases, it may also ease discomfort during opioid withdrawal. Robaxin is available in tablet form or as an injection, usually given in hospital settings.
Is Robaxin an opioid or a narcotic?
No. Robaxin (methocarbamol) is a muscle relaxant, not an opioid or narcotic, and it isn’t scheduled by the DEA. Even so, it can cause sedation and impaired coordination, particularly with other CNS depressants.
NSAIDs are sometimes paired with muscle relaxants; learn more about meloxicam.
Although Robaxin does not produce a strong euphoric high, it can still be misused. People may take larger doses than prescribed to feel calm or relaxed. Those with a history of prescription drug abuse are at higher risk of developing unhealthy habits.
Methocarbamol is not classified as physically addictive, but regular misuse can lead to psychological dependence. Because of this, it should always be taken under a doctor’s supervision. Exploring other muscle relaxers? Review our guide to Cyclobenzaprine (Flexeril) addiction and withdrawal.

Does Robaxin cause withdrawal? How should I stop?
Robaxin isn’t known to cause a classic physical withdrawal syndrome, but tapering is still a good idea after prolonged use to minimize rebound symptoms (e.g., sleep disturbance, anxiety). Always follow a clinician’s taper plan.

Choosing the Right Type of Treatment
Finding the best type of treatment depends on your needs, your support system, and your health status. Residential treatments offer more structure, while outpatient care allows for flexibility. A healthcare professional can guide you in choosing the most effective approach for your situation.
According to the National Institute on Drug Abuse, long-term drug rehab lasting 90 days or more is the most effective approach for lasting recovery.

Frequently Asked Questions About Robaxin (Methocarbamol) Addiction, Side Effects, and Withdrawal
What are the most common side effects of Robaxin?
The most common side effects of Robaxin (methocarbamol) include drowsiness, dizziness, headache, nausea, blurred vision, and lightheadedness. Some people may also experience confusion or lack of coordination. These side effects are usually mild but can become dangerous if the medication is misused or combined with other central nervous system depressants like alcohol or opioids.
What should you not take with Robaxin?
Robaxin should not be combined with alcohol, opioids, benzodiazepines, or other sedatives because of the risk of severe drowsiness, slowed breathing, or overdose. It is also important to avoid taking it with certain prescription medications without medical guidance, as dangerous drug interactions may occur.
Does Robaxin cause constipation?
While constipation is not among the most common side effects, it can occur in some people. Other gastrointestinal issues such as nausea or upset stomach may also develop. If constipation becomes severe or persistent, it should be discussed with a healthcare provider.
Is Robaxin an effective muscle relaxer?
Yes, Robaxin is considered an effective muscle relaxer and is often prescribed for muscle spasms caused by injuries, strains, or other musculoskeletal conditions. However, it should only be used short-term and under medical supervision, as long-term misuse may lead to dependence.
Does Robaxin have narcotics in it?
No, Robaxin is not a narcotic. It is classified as a central nervous system depressant and a muscle relaxant. However, despite not being an opioid or narcotic, misuse of Robaxin can still cause harmful effects and psychological dependence.
What is the most addictive muscle relaxer?
Muscle relaxers such as Soma (carisoprodol) and benzodiazepine-based medications are considered more addictive than Robaxin. While methocarbamol is less likely to cause physical dependence, misuse or taking it in high doses can still lead to psychological addiction.
Can methocarbamol be addictive?
Yes, methocarbamol has the potential for abuse. Although it is not classified as a controlled substance, some individuals misuse it for sedative effects. Over time, this can lead to dependence, withdrawal symptoms, and the need for professional addiction treatment.
Is Robaxin habit forming?
Robaxin is not typically considered highly habit forming, but misuse can lead to tolerance and psychological dependence. People who take it for longer than prescribed or at higher doses than recommended are at greater risk of developing a habit.
Does Robaxin need to be weaned off?
Yes, tapering off Robaxin gradually under medical supervision is recommended to avoid withdrawal symptoms such as anxiety, insomnia, tremors, or irritability. Abruptly stopping after extended use may worsen side effects.
What are the side effects of coming off muscle relaxers?
When discontinuing muscle relaxers, some individuals experience withdrawal symptoms such as anxiety, mood swings, restlessness, nausea, and trouble sleeping. The severity depends on the type of muscle relaxer, dosage, and length of use.
What is the withdrawal time for methocarbamol?
Methocarbamol withdrawal symptoms usually appear within a few days after stopping use and may last about a week. However, cravings, anxiety, or mood changes may persist longer, making professional treatment and support important for recovery.
How long do drug withdrawal symptoms last?
Withdrawal symptoms vary depending on the drug, dose, and individual factors. For muscle relaxers like Robaxin, most physical symptoms fade within one to two weeks, but psychological symptoms such as cravings or depression can linger for several weeks or months.
Is Robaxin an opioid?
No. It’s a muscle relaxant and not an opioid or narcotic.
Is methocarbamol addictive?
Physical dependence is uncommon, but misuse (especially with other depressants) can lead to psychological dependence and dangerous sedation.
Can Robaxin get you high?
Robaxin has low euphoric effect on its own; sedation is more typical. Mixing with alcohol/benzos/opioids is what makes it risky.
How long will Robaxin be in my system?
Most people clear it in ~5–10 hours; specialized urine tests may detect metabolites for ~4–5 hours post‑dose.
Does Robaxin cause withdrawal?
Not typically; tapering is still recommended after long‑term use.
What shouldn’t I take with Robaxin?
Avoid alcohol, opioids, benzos, sleep meds, or other sedatives unless a clinician directs otherwise.
What is Robaxin used for?
Robaxin is the brand name for methocarbamol, a muscle relaxant prescribed for muscle spasms, tension or injuries. It works by calming the central nervous system and blocking pain signals to the brain, and doctors often pair it with physical therapy and rest. It is sometimes also used to ease discomfort during opioid withdrawal. It comes as a tablet, or as an injection usually given in hospital. It is not a narcotic.
Will Robaxin make you sleepy?
It can. Drowsiness is the first of the common side effects the page lists, alongside dizziness, nausea, blurred vision, stomach discomfort and low blood pressure. Taken as directed these tend to be mild. The warning it attaches is about combinations: misused, especially with alcohol or other substances, the effects can become severe and in extreme cases life threatening.
