White pill with 115


Methocarbamol is a muscle relaxant that is used to alleviate pain, such as the pain and discomfort of injured muscles.

Along with physical therapy and rest, the drug can help relieve muscle spasms brought on by strains, sprains, and other muscle injuries.

Methocarbamol, which is available only by prescription, comes as a tablet in different strengths—Methocarbamol 500 mg or Methocarbamol 750 mg.

It was first approved by the Food and Drug Administration (FDA) in 1957 under the brand name Robaxin; today, it’s manufactured by Schwarz Pharma. Methocarbamol is also available as a generic drug.

Methocarbamol Warnings

Because methocarbamol is a central nervous system depressant, it can cause drowsiness and slow down your reaction time.

You should be careful taking this drug if you need to drive, operate machinery, or perform any activity that requires you to be alert.

These effects can increase if you combine methocarbamol with alcohol.

It’s unclear whether methocarbamol is safe to take during pregnancy.

It should be taken only if your doctor feels the risks outweigh the benefits. Methocarbamol should be used with caution if you are breastfeeding.

Methocarbamol is not approved for anyone younger than 16.

Before taking methocarbamol, it’s important to tell your doctor about all your medical conditions, as well as your alcohol use and drug use. Tell your doctor if you have allergies to any medications.

Also tell your doctor if you are pregnant, may become pregnant, or are breastfeeding.

Methocarbamol “High” and Recreational Use

Numerous online and anecdotal reports have suggested that some people abuse methocarbamol for a narcotic-like “high,” because it can cause drowsiness.

Research indicates that methocarbamol has very little narcotic effect, and that any narcotic-like effects with the drug can only be achieved when it is taken at high-than-recommended doses. This can lead to serious side effects.

Take methocarbamol only as directed by your doctor, and keep this and all other drugs away from children, teenagers, and anyone for whom the drug has not been prescribed.

Methocarbamol for Dogs, Cats, and Horses

Methocarbamol is also FDA approved for use as a prescription muscle relaxant for dogs, cats, and horses.

It is used to treat muscle spasms caused by various diseases (such as intervertebral disk disease or “slipped disk”), traumas, or the ingestion toxic substances (including permethrin poisoning in cats).

For animal use, methocarbamol is available in 500 mg tablets. Dosing is based on weight.

Methocarbamol requires a prescription from your veterinarian.

Robaxin (Methocarbamol) Addiction: Side Effects, Detox, Withdrawal, and Treatment

What is Robaxin (Methocarbamol)?

Methocarbamol (Robaxin) is a central nervous depressant and a muscle relaxant. Robaxin may be prescribed to treat individuals who are suffering from the symptoms of lockjaw or from injury. It is intended to provide short-term relief from acute muscle pain and stiffness and is often used alongside other forms of treatment. It is also sometimes used to relieve symptoms of opioid withdrawal, specifically muscle cramps and spasms.

Robaxin is generally sold in tablet form but it may also be administered intravenously in clinical settings. It works by blocking sensations of pain that are sent to your brain. Although it is not an opioid drug, it can produce similar side effects such as drowsiness and dizziness, which some people may mistake as being “high” on the drug.

Methocarbamol is sold under the brand name Robaxin and a generic version is also available. Users can only legally get it with a valid prescription. A dose of Robaxin is typically three 500 mg tablets taken four times daily or two 750 mg tablets taken four times daily.

Robaxin (methocarbamol) is not generally considered an addictive drug because it does not produce feelings of euphoria, withdrawal symptoms, and unlike opioid painkillers, it does not relieve generalized pain. However, when it is taken in extremely high doses, it can cause drowsiness and dizziness, which can increase the likelihood of users abusing it.

Slang for Robaxin (Methocarbamol)

Robaxin is not as frequently abused as other prescription medications, so currently, there are no known street names for methocarbamol or Robaxin.

About Robaxin (Methocarbamol) Abuse and Addiction

Robaxin is not a frequently abused drug, but some people may mistake the dizziness and drowsiness it causes for a “high.” As a result, they may misuse it in high doses. People who have a history of narcotic abuse and addiction are more likely to abuse Robaxin and become psychologically addicted to it.

Methocarbamol also interacts with other central nervous system depressants like prescription painkillers, cough and cold medicine, tranquilizers, sleeping pills, or anti-anxiety drugs, and may enhance their effects when taken simultaneously. Taking Robaxin with other CNS depressants is highly discouraged and can cause an overdose.

The best way to prevent Robaxin addiction and abuse is to take it exactly as directed by a doctor and avoid using other drugs or alcohol while taking it unless you’ve previously spoken with your doctor about it.

Side Effects of Robaxin (Methocarbamol) Abuse

Abusing Robaxin can lead to harmful physical and psychological side effects. Some of the most common side effects of Robaxin (methocarbamol) abuse include:

  • Drowsiness
  • Dizziness
  • Stomach pain
  • Nausea
  • Low blood pressure
  • Blurred vision
  • Lightheadedness

Chronic abuse of Robaxin has also been shown to cause suicidal thoughts or behaviors and someone who abuses it regularly with other CNS depressants may also be more likely to overdose. Signs and symptoms of a Robaxin overdose may include seizures or loss of consciousness.

Signs and Symptoms of Robaxin (Methocarbamol) Abuse and Addiction

While Robaxin addiction is not common, people who have a history of misusing opioid painkillers or substance abuse, in general, may be more likely to misuse methocarbamol. Signs and symptoms of Robaxin (methocarbamol) addiction and abuse may include:

  • Taking large doses of Robaxin
  • Using Robaxin recreationally (without any legitimate medical reason)
  • Taking Robaxin with other drugs or alcohol to enhance the effects
  • Faking symptoms to get a prescription for Robaxin
  • “Doctor shopping” to get multiple prescriptions for Robaxin
  • Having cravings for Robaxin
  • Feeling like you need Robaxin to function normally
  • Neglecting other responsibilities like work, school, or family to abuse Robaxin
  • Isolating yourself from friends and family

Robaxin (Methocarbamol) Detox and Withdrawal

Robaxin isn’t known to cause any withdrawal symptoms, but medical professionals still recommend that recreational users and people who use it for legitimate medical reasons gradually transition on or off of the drug instead of starting or quitting abruptly.

Treatment for Robaxin (Methocarbamol) Addiction

If you are abusing Robaxin to enhance the effects of your drug of choice, you may choose to enroll in a professional treatment program to address the addictive behaviors. Long-term drug rehab is an effective way to combat addictive behaviors and according to the National Institute on Drug Abuse (NIDA), substance abuse treatment that lasts at least 90 days provides more positive treatment outcomes for clients and greatly reduces the risk of relapse.

Drug rehab for Robaxin addiction may be comprised of several different treatment methods including:

  • Educational lectures
  • Recovery programming (12-step or a similar program)
  • H&I meetings
  • Life skills development
  • Introduction to yoga and meditation
  • Family therapy, individual therapy, and group therapy
  • Specialized therapies like music therapy, pet therapy, art therapy, etc.

Inpatient Drug Rehab vs. Outpatient Drug Rehab for Robaxin (Methocarbamol) Addiction

Two common kinds of drug rehab that may be used to overcome Robaxin addiction are inpatient residential rehab and outpatient rehab. Both of these types of treatment are equally recovery-focused, but each one offers different qualities that may be more or less advantageous for you depending on your circumstances.

Either inpatient or outpatient rehab can help you achieve sobriety and provide the tools and skills you need to maintain it long-term, but here is a side-by-side comparison.

In residential rehab, clients:

  • Live at the rehab center temporarily while they complete treatment
  • Adhere to a structured daily schedule set forth by leadership staff
  • Attend group and individual therapy sessions
  • Participate in various types of specialized therapies and recovery-focused activities
  • Have immediate access to medical and clinical staff

In outpatient rehab, clients:

  • Live at home or in a sober living home while attending outpatient group sessions
  • Complete homework assignments independently outside of group rehab
  • Maintain personal responsibilities such as a job, school, and/or family responsibilities while attending treatment
  • Have limited access to medical and clinical staff

Depending on your treatment needs, residential or outpatient rehab may be a better fit. Fortunately, you don’t have to make this determination on your own. A member of the admissions team at the rehab center of your choice can help you determine which type of treatment best suits your needs. He or she may also provide more information about payment options for rehab. Most often, your payment options drug rehab will include:

  • Health insurance benefits
  • Employee Assistance Programs (EAP)
  • Financed healthcare loans
  • Credit cards
  • Crowdfunding
  • HSA funds

Continued Care Options for Robaxin (Methocarbamol) Addiction Treatment

Even after you’ve completed rehab, you may choose to continue your recovery work with a continuing care program like sober living or aftercare. These types of programs are geared towards people who are new to recovery and who need additional support to sustain a sober lifestyle.

Robaxin addiction, or any other drug addiction, cannot be overcome in a matter of days or even weeks. Recovery is a life-long process but long-term treatment can help make the transition into a new lifestyle easier.

Sober Living Programs

Sober living homes offer safe, sober, and comfortable living environments for men and women in all stages of recovery. A sober living home can be an apartment or a residential home, but the rooming options will vary greatly depending on the facility. Some homes offer private rooms, some offer shared rooms, and others offer both. Some sober living programs are also pet-friendly, so residents can bring their furry friends to live along with them.

Sober living programs are designed to bridge the gap between residential treatment and independent living by providing recovery support services like:

  • Regular drug and alcohol testing
  • Tiered recovery programming
  • Individual monitoring/one-on-one support
  • Employment assistance
  • Educational planning
  • Volunteer placement

The cost of a sober living home will vary depending on several different factors, such as:

  • The location of the home
  • The amenities provided
  • The available room options
  • The recovery support services offered

Regardless of the program’s cost, most sober living residents pay a monthly fee, similar to rent.

Aftercare Programs

Aftercare is another recovery support program that is designed to help individuals who have recently completed rehab or who are facing a difficult or transitional stage in life that may compromise their recovery.

Aftercare is comprised of a series of outpatient meetings that provide a safe and accepting place for individuals to talk about the struggles of life in recovery, share personal advice and wisdom, and receive support from sober peers and mentors.

If you or a loved one is abusing Robaxin recreationally and you need help quitting, call Nova Recovery Center today. We can help you overcome your substance abuse and start over with a new, sober life.
