Robaxin vs. Valium

Robaxin vs. Valium

Robaxin (methocarbamol) belongs to the Skeletal Muscle Relaxant class of medicines. It is a prescription drug used to treat muscle cramps caused by pain or injury and Tetanus symptoms. Robaxin can be taken alone or in combination with other medications.

Valium (Diazepam) belongs to the benzodiazepine class of medicines. It’s used to treat anxiety, withdrawal from alcohol, and seizures. It’s also used to treat muscle spasms and sedatives before medical procedures. This medicine calms the brain and nerves.

Differences Between Robaxin And Valium

Different skeletal muscle disorders are treated with Robaxin (methocarbamol) and Valium (diazepam). Robaxin is used to treat skeletal muscle conditions, including pain or damage combined with rest and physical therapy, while Valium is used to treat muscle spasms. Valium is also used to treat anxiety, convulsions, and alcohol withdrawal symptoms(Wei, S.U.N., Chong-hui, L.I., Liang-sheng, W.A.N.G. and Si-lan, D.A.I., 2010).

Robaxin and Valium are two different types of drugs. Valium is a benzodiazepine, while Robaxin is a muscle relaxant.

While they may have similar side effects like nausea, constipation, memory issues, loss of balance or coordination, blurred or double vision, dizziness, some side effects might differ between Robaxin and Valium. Side effects of Robaxin that are different from Valium include stomach upset, vomiting, flushing (warmth, redness, or tingly feeling), sleep problems. In contrast, Side effects of Valium that are different from Robaxin include drooling, dry mouth, slurred speech, or loss of interest in sex.


For Robaxin: Except in the case of tetanus, the total adult dosage should not exceed 30 mL (3 vials) each day for more than three days. A similar course may be followed following a 48-hour drug-free gap if the problem persists. 

One dose of 1 gram may be sufficient to alleviate mild symptoms. Additional doses of 1 gram may be repeated every 8 hours up to a maximum of 3 g/day for no more than three days in the most severe cases or in postoperative settings where oral administration is not possible.

Taking Valium alongside other sleep aids or medications that restrict your breathing can result in serious side effects or death. Consult your doctor before using opioid medication, a sleeping pill, a muscle relaxant, prescription cough medicine, or anything for depression or seizures. 

Drug Interactions

Patients should be aware that Robaxin might produce drowsiness or dizziness, making it difficult for them to drive. Because Robaxin has a general CNS-depressant impact, patients should be mindful of the potential for adverse interactions with alcohol and other CNS depressants. 

Notify your healthcare professional if you are taking other products that cause drowsiness, such as opioid pain or cough relievers, alcohol, marijuana, drugs for sleep or anxiety, other muscle relaxants, or antihistamines.

Taking Valium alongside other sleep aids or medications that restrict your breathing can result in serious side effects or death. Consult your doctor before using opioid medication, a sleeping pill, a muscle relaxant, prescription cough medicine, or anything for depression or seizures.

Other pharmaceuticals, such as prescription and over-the-counter medications, vitamins, and herbal items, may interact with diazepam. Concomitant use with alcohol is not suggested due to the amplified sedative impact.

What Happens If You Take Robaxin And Valium Together?

When Valium is used with Robaxin, side effects like dizziness, drowsiness, disorientation, and difficulties concentrating may be increased. Some people, especially the elderly, may have difficulty thinking, judging, and physical coordination. While using these medications, you should avoid or limit your alcohol use. Also, until you know how the prescriptions affect you, avoid tasks that need mental attention.

Which One Is Better - Robaxin or Valium?

Many healthcare professionals prefer Robaxin over Valium because it has been thoroughly researched. It’s also less expensive and sedating than some other solutions. In recent studies, 44 percent of people who took methocarbamol for up to 8 days experienced total pain relief (compared to 18 percent who did nothing) – and this was without any significant side effects.

Benzodiazepine drugs such as Valium are often prescribed as muscle relaxants. However, these aren’t really preferred because they don’t function as effectively as they should, are sedating, and can lead to addiction.(Simpson, M.H., Managing Cancer Pain.)
Can You Take Ibuprofen And Naproxen Together?

Can You Take Ibuprofen And Naproxen Together?

Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that reduces certain chemicals that cause pain and inflammation in the body. It reduces fever and treats pain or inflammation caused by headache, back pain, toothache, arthritis, or minor injury. It is safe for use in adults or children six months or older.

Naproxen is also a nonsteroidal anti-inflammatory drug. Like Ibuprofen, it works by blocking the chemicals that cause pain and inflammation in the body. It is used to treat inflammation or pain caused by arthritis, tendinitis, bursitis, gout, or menstrual cramps. It is safe for use in children 12 years and older.

Ibuprofen is a short-acting drug, while naproxen is a long-acting drug. Naproxen is more likely to cause an upset stomach. Both these drugs are NSAIDs and are similar in many ways, but there are some differences. It is generally not advised to take Ibuprofen with Naproxen or with any other NSAIDs.

What Happens When You Take Ibuprofen And Naproxen Together?

Combining these two medications may increase the risk of side effects. It can affect the gastrointestinal tract and cause bleeding, inflammation, ulcer, and in some rare cases, can also cause perforation. Gastrointestinal perforation can be fatal, which causes holes in your stomach and intestine. We suggest you take these drugs with food to reduce any risks. You can always talk to your doctor if you have any questions or concerns. Your doctor may prescribe other medications that may not interact with these medications. Seek immediate medical attention if you experience any symptoms of bleeding such as dizziness, lightheadedness, red or black stools, coughing or vomiting blood that looks like coffee grounds, or a severe headache and weakness. Do not stop using any medications without consulting your doctor first. Avoid taking Aspirin, Ibuprofen, or Naproxen within 8 to 12 hours of each other. These NSAIDs may be taken in combination with acetaminophen for additional pain relief. If you have pre-existing medical conditions, tell your doctor.(Polat, O., Karaman, A.I. and Durmus, E., 2005)


A study published by the department of pharmacology at the University of Bordeaux, France, studied NSAID drugs, their safe and effective use, and adverse side effects due to drug-drug reactions. The study reported adverse drug reactions (ADRs), including gastrointestinal bleeding and cardiovascular and renal effects due to NSAID use. In many cases, ADRs may occur due to drug-drug interaction between the NSAID and other medications. When assessing potential risks of ADRs, it is crucial to consider the dose and duration of NSAID use and the type or class of comedication administered (Pacheco, D.P., Manrique, Y.J. and Martinez, F., 2007). Health care professionals can be crucial in educating patients to use the lowest effective dose for the shortest required duration for good balance and safety.

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)

Do consult the medical practitioner if detected any side effects and consume the medication under proper guidance.(Winocur, E., Gavish, A., Volfin, G., Halachmi, M. and Gazit, E., 2001)
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.)
