Robaxin (Methocarbamol) Can Be Highly Addictive?

Robaxin (Methocarbamol) Can Be Highly Addictive?

Robaxin is a skeletal muscle relaxant that, in the generic form, is called Methocarbamol. This medication is primarily used to treat short-term musculoskeletal pain caused by injury, spasm, stiffness. This medication is used in physical therapy along with pain medications. Robaxin works by blocking the nerve impulses (that cause pain) in the brain.

Can Robaxin Lead To Drug Abuse?

Robaxin is not considered to be addictive when taken under control and proper surveillance following the prescription. Robaxin under the recommended dosage does not lead to the feeling of euphoria or does not show any other symptoms of feeling high.

However, when the dosage is more frequent than the prescribed amount, the patient may feel the symptoms of dizziness, drowsiness, or possibly high. This medication can be addictive to those who have a history of addiction. Henceforth, this medication is sold as “prescription-only medication” as it can be addictive when overdosed.

Robaxin is a medication that can interact with other CNS (central nervous system anti-depressants) such as flu medications, sleeping pills, and even pain killers that can enhance the symptoms of euphoric feeling, which can lead to overdose and a sense of “high.” Perhaps it is not suggested to be consumed with any of the above-mentioned medications forms.(Maaswinkel, H., 2020)

Study: Is Robaxin Addictive?

Study: This study was conducted by J Pharmacol Exp Ther.

Aim: To evaluate the results of Robaxin Addiction. This research was performed by gathering the subjects with a history of narcotic drug abuse, including sedative/hypnotics.

Execution: This research was conducted by providing the drug to the subjects with lorazepam and placebo for accurate results. That was measured by the Morphine-Benzedrine group (MGB) scale scores that measured the euphoric feeling and were speculated by giving the dosage of 1, 2, and 4 mg to the mentioned medication as well Robaxin of 2.25, 4.5, and 9 g to different subject groups respectively.

Results: This medication can be addictive when consumed regularly against the prescription. But when taken in high dosage, the MGB scale detected that the subjects felt rather dysphoric due to the accompanying side effects. But Robaxin has the potential to be addictive for those who have a history of narcotic or sedative abuse.(Berger, H., 1961)

How Long Does Robaxin Stay In Your System

How Long Does Robaxin Stay In Your System

Robaxin remains in the urine for up to four hours, from the time of ingestion. However, the range of presence varies depending on the age and health condition of the patient. Robaxin is a brand name of the generic medication methocarbamol. Methocarbamol is a central nervous system depressant used to treat involuntary muscle spasms. Robaxin is sometimes used in the treatment of tetanus. Robaxin belongs to a class of drugs called Skeletal Muscle Relaxants. Robaxin is used with rest and physical therapy to treat skeletal muscle conditions such as pain or injury.

Half Life Of Robaxin

The plasma clearance of Robaxin ranges between 0.20 and 0.80 L/h/kg. The mean plasma excretion half-life ranges between 1 and 2 hours and the plasma protein binding ranges between 46% and 50%.

Robaxin is metabolized through dealkylation and hydroxylation. Essentially all changed and unchanged Robaxin metabolites are eliminated in the urine.(See, S. and Ginzburg, R., 2008)

Factors That Influence Robaxin Stay in The System

Robaxin has a relatively short half-life. In healthy individuals, nearly all Robaxin metabolites are excreted in the urine within four hours of ingesting the drug. The metabolism of Robaxin in the body is influenced by patients’ age and the health of their kidneys and liver. Elderly people in the age range of 69 years take a slightly longer time to eliminate Robaxin in the urine. In other words, methocarbamol has a shorter half-life in elderly persons. Patients in the age range of 69 years take 1.5 hours to excrete Robaxin, while patients in the age range of 53 years take 1.1 hours to get rid of the drug.

Also, it is found that older patients display a decreased fraction of bound Robaxin in the blood, which means that the younger patients utilize the drug more effectively. Patients with kidney problems and are on hemodialysis utilize Robaxin less efficiently and eliminate only 40 percent compared to healthy patients; those who eliminate 46 to 50 percent. Patients with liver cirrhosis due to alcohol misuse have similar efficacy, with only 40 to 45 percent of Robaxin bounding to plasma protein. It is found that only 2 percent of Robaxin will remain in the blood for 24 hours following the final dose in most individuals.(Lu, Y. and Bertoncini, E., 2019)

How long Robaxin Stays in Urine, Hair and Blood

A considerable amount of Robaxin metabolites may be found in one or two hours of ingestion. Robaxin can remain in the urine for up to four hours from the time of ingestion. These ranges depend on the age and health of the patient. In most of the patients, only 2 percent of absorbed Robaxin will remain in the blood for 24 hours, while it could be tested via hair within 90 days, following the final dose.(Tagliaro, F., Carli, G., Cristofori, F., Campagnari, G. and Marigo, M., 1988)

How Long Robaxin takes to Respond

Robaxin starts working in about 30 minutes and its full effects are seen within 2 hours. It is relatively short-acting and needs to be taken three or four times a day, as prescribed by a doctor.

Possible Side effects Of Robaxin

Robaxin may cause serious side effects, that includes:
  •  Lightheadedness,
  • Slow heartbeats,
  • Fever,
  • Chills,
  • Flu symptoms,
  • Seizure(convulsions).
  • Yellowing of your skin or eyes (jaundice)

 These are not all the possible side effects of Robaxin, but there may be many more side effects that may not be severe. But for any side effects, you must consult your doctor.(Forsyth, H.F., 1958)

Who Should Avoid Robaxin

Robaxin is a prescription medicine and is not available over-the-counter. It could only be taken in consultation with a general practitioner. Patients under several conditions should avoid taking Robaxin, which are;(See, S. and Ginzburg, R., 2008).

  • Pregnant women should avoid taking Robaxin due to an increased likelihood of the infant being born with a physical abnormality.
  • Robaxin should be avoided by lactating mothers, too, as it is found in the milk of the mother receiving treatment with the drug. But it is not clear whether it affects the infant adversely on not. 
  • It should be avoided by elders also as it may increase the risk of falls. 
  • It is also not suitable for those who have an allergic reaction to Robaxin.
  • Sedation caused by Robaxin may affect driving or operating heavy machinery of a person.
  • An alcoholic person should also avoid taking this medicine.
  • Patients already on medication of opioids, benzodiazepines, and sedating antihistamines should avoid taking Robaxin.
  • Safety and effectiveness in children below 16 years of age are still to be established.  
  • People who have a history of narcotic abuse and addiction are more likely to abuse Robaxin and become psychologically addicted.
Can You Take Gabapentin And Robaxin Together?

Can You Take Gabapentin And Robaxin Together?

Gabapentin is an anti-epileptic drug called as anticonvulsant. Gabapentin affects chemicals in the body that cause seizures and some types of pain. It belongs to a drug class called Gamma-aminobutyric acid analogs.

Robaxin is a muscle-relaxing drug and belongs to a drug class called Skeletal muscle relaxants. It works by blocking nerve impulses and the pain signals sent to your brain.

No, typically, we won’t suggest you take Gabapentin and Robaxin together. Gabapentin is a pain killer, while Robaxin is a muscle relaxer. Taking these two medications together might increase the side effects caused by them. However, if the doctor feels the need to, there can be exceptions made to the use of Gabapentin and Robaxin together.


A study conducted by The University of Texas Medical Branch studied multimodal pain pump groups with the added use of Gabapentin and Robaxin together for post-operative scoliosis surgery. We believe it is the first study that examined the use of Gabapentin and Robaxin together for pain management.

Gabapentin and Robaxin were both given orally. Gabapentin 3 times a day and Robaxin (Methocarbamol) every 6 hours if the patient weighed over 33 kg. The endpoints were analyzed for the length of stay in the hospital, post-operative gastrointestinal retention, and infection rate. The study concluded in showing improvements in pain management by the use of elastomeric pumps post-operation. The addition of Gabapentin and Robaxin showed a trend towards further improvements in the patients.(Carlson, J.D., Peloquin, J. and Falowski, S.M., 2016)

There is not much data on the use of Gabapentin and Robaxin when used together. It is typically advised not to use them together as there can be adverse side effects; however, it can be used under very specific circumstances if the doctor feels the need.(Lee, T.J., 2010)

What Happens When You Take Gabapentin And Robaxin Together?

Using Gabapentin and Robaxin together may increase the side effects such as dizziness, drowsiness, difficulty in concentration, and confusion. Some people may find a problem in judgment, motor coordination, and impairment in thinking, especially the elderly. 

Try to avoid or limit alcohol use during the treatment of these medications. Also, you must try to avoid activities that require mental alertness, such as using heavy machinery or driving a vehicle, until you understand how the medicine affects you. 

How Will You Manage The Side Effects?

Patients should be carefully monitored for excessive or prolonged CNS or respiratory depression. Proper dosage titration may be required during the time of the treatment. People who need help or support to walk should be counseled to avoid hazardous activities which require mental alertness and motor coordination.

If you have any concerns or facing side effects due to the medication, consult your doctor. It would help if you tried to tell your doctor of any pre-existing conditions or medications you are using.(Kriel, H.H. and Yngve, D., 2019)

What Combination Of Drugs Could You Take Instead?


Taking Gabapentin with some OTC medications that treat allergy and pain relief is considered safe. However, you must check with your doctor before taking any combination of medicines. 

Some common combinations with Gabapentin with OTC medicines can include:

You can use Antacids with Gabapentin, but it is recommended to take Gabapentin at least 2 hours before any Antacid. 

Gabapentin can be generally used with other anticonvulsants for duplicate therapy as they serve the same purpose.


Some common medications you can take with Robaxin include:

These combinations can help manage pain with the right dosage.

(Note: Always follow proper dosage and other guidelines prescribed by your doctor.)

Robaxin vs Baclofen Which is better?

Robaxin vs Baclofen Which is better?

Robaxin and Baclofen are the medication that is used for skeletal muscular relaxation. Robaxin and Baclofen are medications accustomed to healing any muscle pain or muscle injury. Therefore, to know which one of these drugs is better, let’s post-mortem both the drugs.

What is Robaxin and Baclofen?

Robaxin is a medication that belongs to the skeletal muscle class that is mainly used for treating muscular pain, muscle spasms, or any muscular injury and is also used for tetanus used primarily in or during the process of recovery, physical therapy, or any other treatment. (Sibrack, J. and Hammer, R., 2020. Methocarbamol)
Baclofen is another muscle-relaxing drug that comes under the brand Lioresal, which is primarily used for treating muscle pain due to injury or pain in general amongst people who suffer from spinal-related issues or multiple sclerosis. (Penn, R. and Kroin, J., 1985))Now that we are well versed in this drug let’s see how it works. Now that we are aware of the purpose of this medication let’s look further at how does both the muscle relaxer works?

How Both the Medication Works?

As previously mentioned, Robaxin is a muscle-relaxing medication used to tame muscular injuries and tetanus. This muscle relaxer medication blocks the nerve impulses or painful sensations that lead to almost nil feeling of the pain. Thus, it is useful when injured. (Forsyth, H.F., 1958. Methocarbamol) Therefore, this is how Robaxin works. Now, let’s scrutinize intake or the dosage of this medication.
Baclofen is the medication that can be consumed orally or directly injected into the spinal cord; this thus, acts on the spinal cord nerves and decreases the pain and number of muscle spasms or the pain in the spinal cord. (Merino, M., Peris‐Ribera, J.E.,1989)Now that we know about the working of both the medication, let’s look at other factors such as the dosage, side effects, etc.

Dosages for Robaxin vs Baclofen

  • Robaxin Dosage in the form of Tablet– in the case of adults, this medication’s oral dosage can be from 500-750mg, depending upon the factors such as the extent of pain, injury, etc.
  • Injection for adults and pediatrics: In the case of injection, the dosage of this medication is about 100mg for both adults and pediatrics.
  • For Tetanus in Adults: The dosage of this medication is about 300mg which may or may not increase.
  • Pediatrics: The dosage in the case of pediatrics is 15mg for three days. (Ferslew, K.E., Hagardorn, A.N. and McCormick, W.F., 1990)
Thus, this was the dosage description. Do not consume more than what is recommended by the certified doctor or physician, or it can be hazardous.
This medication should be consumed only when prescribed and in the recommended amount by the doctor. Do not overdose or use it without any prescription. Baclofen in the case of adults: Baclofen tablet comes in about 10mg. However, the recommended dosage is about 60mg per day which can be increased according to the doctor’s consultation. This medication is started by providing 5 mg, which is then increased o 15 or 20 mg in one day. Pediatric: In the case of children above eight years, the daily dosage consumption orally is 40mg per day. (Lubsch, L., Habersang, R., Haase, M. and Luedtke, S., 2006) Now that we are well versed with dosage let’s see the side effects of consumption of both the medication.
For heavily discounted Robaxin and Baclofen

Side Effects of both the Medication

There are several common side effects of Robaxin Therefore, let’s have a look at them. 

Common Side effects

  • Drowsiness or feeling sleepy
  • Nausea or vomiting 
  • Blurred or doubled vision 
  • Insomnia 
  • Lack of brain functioning like; loss of memory, confusion, etc.

Thus, there are a few common symptoms that you need not worry about as it only lasts for a few days; either way, consult your doctor if you undergo any of these symptoms. However, there is a possibility of facing severe symptoms; however, it is a rare case. Thus, let’s have a look at them. 

Adverse Effects 

  • Fever or flu 
  • Light-headedness
  • Slower heartbeats
  • Jaundice 

These are a few adverse symptoms; if you undergo any, consult your doctor as quickly as possible. Now that we are conscious of all these symptoms, let’s look at a few key factors that are a few things to remember.


  • Do not consume this medication if suffering from any of these:
  • Kidney diseases 
  • Epilepsy or seizures 
  • Myasthenia gravis (a long-term condition that causes adverse muscle weakness)
  • In the case of Pregnancy, consult the doctor before consumption, as it can be unsafe for the unborn baby.
  • This medication can be interactive, and thus before consuming other medicines, consult your doctor, or it can be hazardous to health. 
  • Do not consume this medication if not prescribed by a certified doctor or physician. 
  • 16 years or younger are not suggested to consume this medication; however, consult the doctor before consumption. 

Baclofen, like every drug, has its side effects which can vary from being common or minor to extreme or adverse, and thus, one must consult the doctor in either of the cases.

Common Side effects

  • Headache 
  • Nausea 
  • Insomnia 
  • Increased urination 
  • Drowsiness 

Thus, these are the common symptoms of Baclofen with is similar to that of Robaxin. Therefore, let’s look at the extreme symptoms. 

Adverse Effects 

  • Severe fever 
  • Breathlessness 
  • Seizure 
  • Tingling sensation within the body 

Thus, these are some adverse symptoms. Therefore, in case you undergo any, do consult with your doctor or physician. Do not try to solve it on your own, and with this, we come to the next factor that is the key points that one must follow.


  • Do not consume this medication if you suffer from any of these 
  • Epilepsy or seizure might make it worse. 
  • Kidney diseases 
  • Mental disorder 
  • Stroke 
  • Blood clot 
  • Nerves system disorder

Strictly, do not indulge in taking this medication if you suffer from any of the issues mentioned above.

  • If pregnant or breastfeeding, consult your doctor before consuming this medication as it can lead to withdrawal symptoms. 
  • Do not consume this medication If not prescribed by a certified professional 
  • Children below 8 years are not recommended to consume the medication.

Thus, these are the key points to remember in any case, consult the doctor before taking any risk. Therefore, now that we are aware of both these medications, the main question arises which one is better? Let’s disclose the answer.

Which one is better? Robaxin or Baclofen

Now that we are well aware of the essential properties of both these medications, Both of these medications have similar properties but at the same time different uses. Yes, it is a muscle relaxer; however, Robaxin is mainly used for skeletal muscle tissues, and Baclofen is used primarily for the distress in the spinal cord and, thus, is beneficial and effective in both their separate cases. Therefore, remember to consult the doctor before consuming these drugs.

Is Robaxin Effective on Headaches?

Is Robaxin Effective on Headaches?

Although not proven that Robaxin is effective for headaches but, some clinical experiments suggest that Robaxin, when combined with other medications, can be effective on headaches. A seventy-five-year-old, 60 kg woman without significant medical history, presented to the Long Island College Hospital Emergency Department with an acute inferior wall MI in 1990. The patient was discharged from the hospital on day five with a regimen of isosorbide dinitrate, diltiazem, metoprolol, and aspirin. The patient remained well until November, 1990, when she began to experience headaches. By February, the patient felt well except for an occasional headache, which responded to acetaminophen. Isosorbide dinitrate was discontinued. In early June, the patient noticed an increase in frequency and intensity of the headache, and more disturbing was a charge in its character, which was described as a bitemporal squeezing with radiation to the sternocleidomastoid muscles bilaterally. Methocarbamol and acetaminophen were prescribed. By late June the headaches were intolerable, now associated with dizziness, and the patient underwent CT of the brain which disclosed a large left SDH. There was no history of head trauma, alcohol abuse, or seizure disorder. (Case Report)

How to consume Robaxin

how to administer Robaxin
Robaxin should be taken exactly as directed by your doctor. Read all drug guides or instruction sheets and follow all guidelines on your prescription label. Robaxin oral is a medication that is taken by mouth. After the first two or three days of treatment, you may need to reduce your dose. Follow your doctor’s dosing recommendations carefully. Robaxin injection is delivered as an infusion into a vein or as a muscle injection. This injection will be given to you by a healthcare provider. Before starting the oral form, the injection is normally administered as a single dosage. When the medicine is injected, tell your caretakers if you have any burning, pain, or swelling around the IV needle. (Uccellani, E.L., 1960)

Dosage in Different age groups

For the first 48 to 72 hours, adults with musculoskeletal discomfort should take three 500 mg capsules by mouth four times a day, then two tablets four times a day to keep spasms at bay. If using 750 mg tablets, take two pills by mouth four times a day for the first 48 to 72 hours, then one tablet every four hours or two tablets three times a day to keep spasms at bay. Injections are given every 8 hours at a dose of 1 gram intravenously or intramuscularly, with a maximum of 3 grams a day for three days. For Tetanus spasms in adults, inject 1 to 2 grams intravenously every 6 hours as needed, up to a maximum of 24 grams per day. In children, inject 15 mg/kg intravenously every 6 hours as needed. For three days, the cumulative dose should not exceed 1.8 g/m2. (Boakes, J., Peach, J.P. and McGill, S.M., 1998)

What are the Effects of Robaxin with Alcohol?

What are the Effects of Robaxin with Alcohol?

Robaxin or methocarbamol is a muscle relaxant medication that works by blocking nerve impulses or, in simple words, the pain sensations that are sent to your brain. Robaxin is used to treat medical cases that involve skeletal muscle conditions such as pain and injury. Robaxin is prescribed to patients to reduce involuntary muscle spasm and the pain associated with it.

Ingredients of Robaxin

Robaxin contains one active ingredient, methocarbamol, which is an effective muscle relaxant that reduces muscle spasms.

Along with Methocarbamol, Robaxin contains a few inactive ingredients as well, namely

  • corn-starch
  • magnesium stearate
  • povidone
  • sodium lauryl sulfate
  • sodium starch glycolate
  • stearic acid


The general dosage for adults suffering from muscle spasm is,

For moderate to low symptoms: 1g IV or IM once, then switch to oral administration.

For severe symptoms/ Post-operative conditions: 1g IV or IM every 8 hours.

The maximum dosage for an adult is 3g in a span of 24 hours. A higher dosage is recommended for post-operative conditions in the first 48 to 72 hours; the dosage shall be reduced gradually to 4000 mg once a day.

Why Shouldn’t you Mix Alcohol and Robaxin?

effects of mixing alcohol with robaxin
Robaxin or methocarbamol is a muscle relaxer medication. Consuming alcohol with a muscle relaxant is discouraged by medical experts because both muscle relaxants and alcohol depress your central nervous system. They slow down your brain activity which further slows down your heart rate and your breathing as well. Since both Robaxin and alcohol have a depressing effect on your body, consuming both will create a compound and intensify the side effects it possesses. Meaning the side effects like dizziness and drowsiness will be doubled. (Ferslew, K.E., Hagardorn, A.N. and McCormick, W.F., 1990)

Effects of Alcohol on Intake of Robaxin

Consuming alcohol along with Robaxin and Soma is not advisable. Alcohol can cause severe effects on your body if taken along with Robaxin. As mentioned earlier, Robaxin alone can make you lightheaded, dizzy, and drowsy; if you consume alcohol over Robaxin, it will act as a catalyst and intensify all the side effects Robaxin, as well as alcohol, has on the central nervous system. Patients taking high dosages of Robaxin are at an increased risk of the side effects Robaxin possesses. The side effects range from normal dizziness and drowsiness to potentially fatal heart rate fluctuation and suicidal ideation. If you have been experiencing such side effects, you must speak with your doctor immediately. Alcohol can intensify such side effects and cause a serious threat to your life. Mixing alcohol with Robaxin can lead to unmanageable drowsiness and poor coordination. (Lee, W.S., Lee, J.Y., Sung, W.Y. and Seo, S.W., 2014) Mixing alcohol with Robaxin can have some severe side effects like,
  • increased drowsiness or tiredness
  • dizziness or light-headedness
  • slowed breathing
  • reduced motor control or coordination.
  • Problems with memory.
  • Increased risk of seizure
  • Increased risk of overdose
Both alcohol and muscle relaxants are addictive substances. Long-term use of Robaxin can increase the risk of being addicted to it.

Things to do if you have Already Mixed Alcohol With Robaxin

If you have already mixed alcohol with Robaxin, stop drinking immediately. This might help you not to increase the side effects. It is advised to seek help from a medical professional if you have had more than one drink.

Get help from a medical professional if you notice these symptoms,

  • Vomiting or nausea
  • slowed breathing
  • feeling weak
  • impaired movement/ lack of coordination
  • palpitation or arrhythmias
  • low blood pressure
  • seizures

Side effects of Robaxin

Side effects of Robaxin

Common Robaxin side effects may include:

  • Headache, dizziness, drowsiness.
  • Fever
  • Confusion, problems with memory.
  • Nausea, vomiting, upset stomach.
  • Blurred vision, double vision
  • Insomnia
  • Lack of coordination.

Robaxin can have some serious side effects on some patients, such as lightheaded feeling like you may pass out, slow heartbeat, seizure jaundice, pain/bruising/ swelling, or skin changes. Consult a doctor immediately if you start seeing these side effects.


It is not advisable to consume alcohol over Robaxin. Robaxin being a muscle relaxant, can cause depressive impacts on your body, and mixing alcohol with it will not only double the side effects but also prove to be fatal for your life. If you find yourself consuming alcohol along with Robaxin, get immediate medical help as soon as possible.

Zanaflex vs Robaxin

Zanaflex vs Robaxin

The generic name for Zanaflex is tizanidine, and it acts as a short-acting muscle relaxer. It mainly works by blocking the pain sensations, i.e., nerve impulses directed to your brain. 

Conditions like cerebral palsy or other neurological disorders are treated by Zanaflex, which is a prescription medicine. The symptoms like muscle stiffness (spasticity) are associated with the neurological disorder is treated by this drug. Zanaflex may be safe and effective for children, but it’s not known if they work because there has never been a clinical trial on them before. The safety and effectiveness data explicitly related to children under 18 has not yet been published; however, this does not mean you shouldn’t give them one chance if your child falls.

The generic name of Robaxin is methocarbamol which is also a muscle relaxer to treat skeletal muscle conditions such as injury.mRobaxin is a prescription medicine used to treat the symptoms of muscle spasms caused by pain or injury and Tetanus. 

They belong in a group known as Skeletal Muscle Relaxants, which includes Valium, among others; not only does it help relieve your discomfort, there has been some evidence suggesting these drugs can actually decrease seizures from epilepsy conditions such as Lennox Gas taut Syndrome.

Are Robaxin and Zanaflex the same thing?

Zanaflex and Robaxin are both muscle relaxants which is used for relaxing the muscles in slightly different ways. Robaxin can be used with therapy and rest to treat skeletal muscle conditions such as injury and pain.

If your muscles suffer cramping after a workout or swimming, then you could use Zanaflex to treat them. It also uses for muscle tightness, the condition like spasm is caused by conditions such as spinal injury.

You may see similar side effects of Zanaflex and Robaxin, including dizziness, skin rash, drowsiness, vomiting, and constipation. It’s not like there are only similar side effects of Robaxin and Zanaflex; some side effects of Robaxin are different from Zanaflex that includes:

  • Nausea
  • Stomach upset
  • Confusion
  • Loss of balance or co-ordination
  • Headache
  • Blurred vision
  • Memory problems
  • Eye redness
  • Spinning sensation
  • Stuffy nose
  • Itching
  • Sleep problems
  • Double vision
  • Diarrhea
  • Dry mouth
  • Fever
  • Muscle weakness
  • Sweating
  • Fatigue
  • Numbness or tingling
  • Back pain
  • Increased muscle tone or spasms
  • Nervousness
  • Anxiousness

Studies have shown that both drugs Zanaflex and Robaxin may interact with some other medicines that can make your breathing slow and could make you dizzy and sleepy. Other drugs may include prescription cough medicines, anxiety, sleeping pills, and depression, narcotics, and muscle relaxers. It is seen that if consumption of Zanaflex stops suddenly after long-term use, then you may have some withdrawal symptoms like anxiety, fast heartbeats, tremors, and dizziness.

For both, Robaxin and Zanaflex at a reduced cost

Robaxin vs. Flexeril: who is more Effective?

Flexeril is the most studied drug and hence has more supporting proof of its effectiveness. According to the experiment done on patients, they felt slightly sounder improvements in local pain with Cyclobenzaprine (48% vs. 40%).

Methocarbamol is the best-known brand, while Roboxin is an effective muscle relaxant recommended as a pain reliever for short-term muscle pain and muscle spasms. Methocarbamol is helpful in the treatment of seizures and muscle spasms as a result of the ingestion of toxic substances in cats and dogs.


Robaxin is for short-term treatment as prescribed by your physician. Similarly, Flexeril is not used for more than 2-3 weeks. Both Flexeril and Robaxin are used as muscle relaxants. It depends on your condition and medical history, which will be more effective for you. Take guidance from your health provider; they will direct the best suitable drug for you after examining your condition.

Another option is to select a specific muscle relaxant (such as methocarbamol or other drugs of the same class) based on the quality of the drug and the condition of the patient. When considering skeletal muscle relaxants for use in the elderly, as an aid to treat chronic pain, or in patients with multiple comorbidities who receive polypharmaceutical therapy that includes opioids and skeletal muscle medications, the medication selection for each patient needs careful consideration of these factors.


Robaxin is a CNS depressant with sedative and musculoskeletal relaxant properties.

Methocarbamol is mistaken as a narcotic due to its side effects of drowsiness, but it isn’t a narcotic. It is a CNS depressant and muscle relaxant to treat pain.

Both Robaxin and Flexeril drugs are muscle relaxants utilized to manage skeletal muscle conditions such as injury or pain. They are used mutually with rest and physical therapy.

According to the list released, Robaxin is the best muscle relaxant.

Is Robaxin (Methocarbamol) a Controlled Substance?

Is Robaxin (Methocarbamol) a Controlled Substance?

Robaxin was approved on 6th October 1959 by the FDA (Food and Drug Administration). The effect of the drug generally begins within half an hour after consumption. One can take it by mouth or by injection. Geriatric patients should not take the drug. FDA labels the medication as a pregnancy C category.

Methocarbamol interacts with other central nervous system depressants (prescription painkillers, cough and cold medications, sedatives, sleeping pills, and anxiety medications) to enhance their effect when taken orally. Methocarbamol is not an opioid, benzodiazepine, or other prescription medicines used to treat pain or convulsions. Methocarbamol is not a controlled substance in the United States, so its potential for abuse or addiction is low. Like any substance, however, it can be misused and used in ways that are not intended.

Diseases such as kidney or liver disease can also influence the metabolic processes of methocarbamol. A 2014 review of skeletal muscle relaxants found that the first-line drugs were not as effective as muscle relaxants at first. Muscle relaxants were more effective than placebos for short-term relief, but the risk of side effects was 50%.
In 2018, it was the 120th most commonly directed medicine in the United States, with higher than 5 million prescriptions.

Robaxin and Carisoprodol is schedule IV drug used to relieve pain in muscles and relax them. Robaxin got approval in the year 1959 by FDA (Food and Drug Administration).
