Robaxin vs Valium
Introduction
For patients with muscle spasms or tension, certain medications that affect the nervous system can provide relief and manage symptoms. Robaxin and Valium are two such drugs prescribed for these conditions. They each impact different parts of the nervous system but both have muscle relaxing effects in patients.
Robaxin (methocarbamol) is classified as a central nervous system depressant and skeletal muscle relaxant, primarily working on the nerves that control muscular contraction to relieve spasms. It's often used as an adjunct treatment for acute painful musculoskeletal conditions.
Valium (diazepam), on the other hand, is classified as a benzodiazepine which works by enhancing the effects of GABA, a neurotransmitter that inhibits activity in the brain — thus reducing anxiety, relaxing muscles, stopping seizures, inducing sleepiness. As it affects more systems within the body than Robaxin does due to its broader spectrum of action; side-effects may be more pronounced.

What is Robaxin?
Methocarbamol (the generic name for Robaxin) is a muscle relaxant used to alleviate acute, painful musculoskeletal conditions and spasms. Unlike diazepam (Valium), which is part of the benzodiazepine class of drugs primarily known for their anxiety-reducing effects but also used as muscle relaxants due to their sedative properties. Methocarbamol was first approved by the FDA in 1957. It works by suppressing nerve impulses that cause pain sensation and possibly directly relaxing tense muscles, although its exact mechanism isn't fully understood yet.
On the other hand, Valium increases GABA levels—an inhibitory neurotransmitter—resulting in reduced neuronal excitation throughout your body and brain providing not only relaxation of skeletal muscles but also anxiolytic, anticonvulsant and sedative effects. While both medications can be effective, they have different side effect profiles; Diazepam has a potential risk for dependency with long-term use while Methocarbamol's side effects tend to be milder including dizziness and lightheadedness.
What conditions is Robaxin approved to treat?
Robaxin and Valium have been approved for different therapeutic uses:
- Robaxin is primarily used as a muscle relaxant to treat skeletal muscle spasms.
- Valium, on the other hand, is mainly used in the treatment of anxiety disorders. It can also be utilized for alcohol withdrawal symptoms, muscle spasms, seizures and to provide sedation before medical procedures.
How does Robaxin help with these illnesses?
Robaxin works to relieve muscle spasms by interacting with the central nervous system to produce a sedative effect and indirectly reduce muscle tension. It does this through its metabolites that have central muscle relaxant properties. Robaxin is particularly useful for patients who are experiencing acute, painful musculoskeletal conditions.
Valium also acts on the central nervous system but in a different way. Valium, known generically as diazepam, operates by augmenting the effects of GABA (Gamma-AminoButyric Acid), an inhibitory neurotransmitter in the brain. By enhancing GABA's effects, Valium leads to calming actions which can help manage anxiety disorders and symptoms of alcohol withdrawal along with relieving muscle spasms.
Both Robaxin and Valium exert their influence on neuronal activity within the brain albeit via different mechanisms to bring about muscular relaxation; however, their uses differ based upon their respective side-effect profiles and contraindications.
What is Valium?
Valium is a brand name for diazepam, which belongs to a class of drugs known as benzodiazepines. It increases the activity of gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter in the brain, leading to sedative, anti-anxiety and anticonvulsant effects. Diazepam was first approved by the FDA in 1963. As it is not a muscle relaxer like Robaxin (methocarbamol), its mechanism of action and side-effect profile are different. In particular, Valium can cause drowsiness and impaired coordination, unlike Robaxin which typically does not have these side effects but can cause stomach discomfort or blurred vision instead. The GABA-enhancing effect of Valium makes it useful in treating anxiety disorders and symptoms related to alcohol withdrawal; however, caution should be taken due to potential risk for dependency with long-term use.
What conditions is Valium approved to treat?
Valium, which is a medication that falls under the category of benzodiazepines, has been approved by the FDA for the treatment of:
- Anxiety disorders
- Symptoms caused by acute alcohol withdrawal
- Skeletal muscle spasm relief
- Adjunctive treatment for convulsive disorders such as epilepsy
How does Valium help with these illnesses?
Valium, also known as diazepam, is a powerful medication used to treat anxiety disorders and symptoms. It works by enhancing the effect of GABA, a neurotransmitter that inhibits activity in the brain. The boosted action of GABA results in reduced nerve cell activity, thereby calming the body and mind under stress or excitement. Unlike Robaxin which primarily focuses on muscle relaxation as a muscle relaxant, Valium has more widespread effects including reducing anxiety, easing agitation, inducing sleepiness and even suppressing seizures due to its influence over various processes in the central nervous system. Furthermore, it's often prescribed when patients do not respond effectively to less potent medications or may be combined with other drugs for greater efficacy. However, it should be noted that while effective for short-term use because of potential dependency issues associated with long-term use.
How effective are both Robaxin and Valium?
Both methocarbamol (Robaxin) and diazepam (Valium) have long-standing histories of success in treating patients with muscle spasms, tension, and acute pain. Initially approved by the FDA several decades ago, they function via different mechanisms to produce muscle relaxation. Methocarbamol's precise mechanism isn't fully understood but is believed to work centrally in the brain rather than directly on the muscles. Diazepam enhances inhibitory neurotransmission through its action on gamma-aminobutyric acid receptors.
In a double-blind clinical trial conducted in 1981, methocarbamol and diazepam demonstrated similar efficacy in managing symptoms of musculoskeletal conditions as well as comparable safety profiles. According to this study, there was no significant difference between patients receiving Robaxin or Valium regarding their symptom relief from painful muscular conditions.
A review published in 2007 highlights that methocarbamol has been effective since the initial days of treatment for relieving skeletal muscle spasms associated with acute painful musculoskeletal conditions. Its side-effect profile seems favorable over many other drugs used for these conditions; it shows minimal sedation compared to others like benzodiazepines.
However, while a 2012 review indicated that diazepam appears more effective than placebo at reducing spasticity-related pain and sudden onset spasms due to multiple sclerosis or spinal cord injury, use caution because dependency can occur if taken at larger doses or over an extended period.
Nonetheless, both medications are often considered first-line treatments when muscle relaxants are needed. They may be co-prescribed alongside other therapeutic interventions such as physical therapy depending on each individual case's needs. Due to its potential dependency issues and sedative effects including drowsiness & impaired motor function which might affect driving ability or operation heavy machinery , valium should be cautiously prescribed especially those prone addiction history or required maintain alertness during day time .

At what dose is Robaxin typically prescribed?
Oral dosages of Robaxin range from 1500-7500 mg/day, divided into several doses. However, studies have indicated that a starting dose of 1500 mg four times per day is usually enough to manage most muscle spasms in adults. Dosage can be increased after a few days if the response is insufficient but should not exceed 7500 mg/day. For Valium, the standard oral dosage ranges from 2–10 mg two to four times daily for adults depending on the severity of symptoms. The maximum recommended dosage is typically no more than 40 mg/day.
At what dose is Valium typically prescribed?
Valium treatment is typically initiated at a dose of 2–10 mg/day. This can be increased to 20 mg/day, divided into two doses and administered approximately 12 hours apart. The maximum dose is generally around 40 mg/day which can be split into three or four doses throughout the day depending on the patient's response to therapy and clinical condition. If there is no significant improvement after several weeks of administering Valium at a daily dosage of 20mg, an increase in dosage may be considered under close medical supervision. Please bear in mind that all dosages must strictly follow your doctor's instructions due to potential risks associated with this medication like dependence.
What are the most common side effects for Robaxin?
Some of the most common side effects associated with Robaxin include:
- Dizziness or lightheadedness
- Drowsiness or sleepiness (somnolence)
- Nausea or vomiting
- Stomach upset or pain (dyspepsia)
- Blurred vision
- Fever and flu-like symptoms
- Rash, itching, hives
On the other hand, Valium's frequent side effects include:
- Fatigue/weakness (asthenia)
- Dry mouth
- Constipation
- Shakiness/tremor
- Slowed speech -Drowsiness/sleepiness (somnolence) -Nausea/vomiting.
Both medications can cause drowsiness and nausea. However, some unique aspects such as rash for Robaxin and constipation for Valium may influence your choice between these two drugs.
Are there any potential serious side effects for Robaxin?
While both Robaxin and Valium are medications used to relieve muscle spasms, they have different potential side effects. For Robaxin users:
- There may be instances of severe allergic reactions which include symptoms such as hives, difficulty breathing, swelling of your face or throat
- In rare cases, individuals might experience blurred vision and eye problems
- Some patients reported having fast or irregular heartbeats accompanied by shortness of breath and sudden dizziness
- A small number noted low sodium levels in the body causing headache, confusion, slurred speech, severe weakness and loss of coordination
- Severe nervous system reaction may occur characterized by rigid muscles, high fever, sweating confusion etc.
As for Valium use:
- It can lead to increased thoughts about suicide or self-harm; if this happens it is important to seek immediate medical attention.
- Signs of serotonin syndrome like agitation hallucinations fever sweating shivering fast heart rate muscle stiffness twitching loss of coordination nausea vomiting diarrhea could also manifest though these are quite rare
Remember that not everyone experiences these side effects but if you do notice any unusual changes while using either medication consult with a physician immediately.
What are the most common side effects for Valium?
Valium, a commonly prescribed medication for anxiety and muscle spasms, can have several side effects that potential users should be aware of:
- Dry mouth
- Drowsiness or fatigue
- Blurred vision
- Nausea, stomach upset or constipation
- Sleep disturbances (insomnia)
- Feelings of restlessness or nervousness
- Slowed heart rate
- Mental confusion or forgetfulness

Are there any potential serious side effects for Valium?
While Valium is generally well-tolerated, it can occasionally cause severe side effects. If you experience any of the following symptoms while taking Valium, seek immediate medical attention:
- Signs of a serious allergic reaction: hives or skin rash; swelling of your face, lips, tongue or throat; difficulty breathing.
- Altered mental status: confusion, hallucinations or unusual thoughts/behaviors.
- New-onset seizures or increased frequency in patients with pre-existing seizure disorders.
- Symptoms suggestive of dependency development like cravings or withdrawal symptoms on discontinuation.
- Vision changes such as blurred vision or seeing halos around lights.
- Changes in heartbeat rhythms (too fast/slow/irregular).
- Mood alterations including signs indicative of hyperactivity disorder such as excessive talking, decreased need for sleep and feelings unusually energetic. Remember to always take medications under the supervision and guidance of a healthcare professional.
Contraindications for Robaxin and Valium?
Both Robaxin and Valium, along with most other muscle relaxant or anti-anxiety medications, can cause sedation or drowsiness in some people. If you notice an increase in these effects, please seek immediate medical attention.
Neither Robaxin nor Valium should be taken if you are using, or have recently used opioids. Always inform your physician about any medications you're taking; opioids will need to clear from the system for a period of time before starting either Robaxin or Valium to avoid dangerous interactions such as severe respiratory depression.
Additionally, both drugs need careful consideration when prescribed for elderly patients due to increased sensitivity and risk of falls caused by sedation or loss of motor coordination. Both drugs may also lead to physical dependence over long-term use and abrupt discontinuation can lead to withdrawal symptoms like anxiety, restlessness and insomnia.
How much do Robaxin and Valium cost?
For the brand name versions of these drugs:
- The price of 60 tablets of Robaxin (500 mg) averages around $140, which works out to $2.33–$4.67/day, depending on your dose.
- The price of 60 tablets of Valium (5 mg) averages about $220, working out to approximately $3.66/day.
Thus, if you are in the higher dosage range for Robaxin (i.e., 1500 mg/day or higher), then brand-name Valium is less expensive on a per-day treatment basis. Please note that cost should not be a primary consideration in determining which of these drugs is right for you.
For the generic versions of Robaxin (methocarbamol) and Valium (diazepam), costs are significantly lower:
-
Methocarbamol (500mg tablets) is available in packs ranging from 20 up to several hundred capsules with approximate costs starting as low as $0.15 per day and going up to roughly $1 per day for dosages between 1000 and 3000mg per day.
-
Diazepam is available in packs ranging from few dozen up to hundreds capsules (5mg), with the cost starting from as low as about $0.40/day and not exceeding about $2/day depending on dosage strength and quantity bought at once.
Remember: Always consult with your healthcare provider before making any decisions regarding medication choices or changes; this information serves only as a guideline rather than definitive advice.
Popularity of Robaxin and Valium
Methocarbamol, available in generic form and under the brand name Robaxin, is a muscle relaxant used to treat muscle spasms. In 2020, approximately 1 million prescriptions for methocarbamol were filled in the United States. Methocarbamol accounted for around 2% of all muscle relaxant prescriptions in the US.
On the other hand, Diazepam, including brand versions such as Valium, is a benzodiazepine used to treat anxiety disorders and symptoms of alcohol withdrawal. It can also be prescribed for muscle spasms when they are due to neurological diseases like cerebral palsy or paraplegia. Diazepam was prescribed to about 14 million people in the USA in 2020. It accounts for just under 25% of all benzodiazepine prescriptions and around .3% of overall medication prescriptions written annually across all categories. The prevalence of diazepam has been on a general decline over recent years owing to concerns about dependency and potential misuse.
Conclusion
Both Robaxin (methocarbamol) and Valium (diazepam) have a long-standing record of usage in patients with muscle spasms, supported by numerous clinical studies indicating that they are more effective than placebo treatments. In some instances, the drugs may be used together but this is subject to careful consideration by a physician as there are also contraindications between them. Due to their different mechanisms of action - with Robaxin primarily working as a muscle relaxant and Valium acting as an anxiety reducing benzodiazepine - they tend to be prescribed under differing circumstances.
Robaxin is commonly considered for acute musculoskeletal pain or injury, whereas Valium would typically be prescribed for chronic conditions causing muscle spasm or in patients who also suffer from accompanying anxiety disorders.
Both medications are available in generic form which can represent significant cost savings especially for those paying out-of-pocket. Both Robaxin and Valium may require an adjustment period; hence effects might not be noticeable right away.
The side-effect profile does differ somewhat between these two drugs: both being generally well-tolerated but with Valium having potential serious side-effects including dependency due its classification as a controlled substance. For both medications, patients must closely monitor their symptoms when starting treatment and should seek medical help immediately if they notice any severe reactions or worsening condition.
