Methocarbamol tablets are prescribed as an adjunct to rest, physical therapy, and other measures for the relief of discomfort associated with acute, painful musculoskeletal conditions.
Commonly reported side effects include:

- Blurry vision
- Moodiness/mental changes

Less common adverse effects involve low blood pressure, slow heart beat, intestinal blockage and fainting.
Signs of being allergic to Robaxin are mostly skin-related rashes, hives and intense itching. People receiving IV administration who were allergic to the drug have reported severe, potentially life-threatening allergic reactions requiring immediate counter methods.
500 mg and 750 mg
Standard adult oral dosage for this drug is three tablets (500 mg each) or two tablets (750 mg) each no more than four times daily.
Doctors prescribing 500 mg and 750 mg may adjust this dosage depending on patient needs and reactions to it.
This drug may be a general CNS depressant. patients taking tablets need to be cautioned about combined effects with alcohol and other CNS depressants.
- It can cause drowsiness or dizziness, which will impair the ability to operate motor vehicles or machinery.
No, it is not classified as a narcotic. Although it is a muscle relaxant and central nervous system depressant, it is not an opiate and does not target opioid receptors in the brain.
- Due to the dizziness and drowsiness caused by Robaxin, this drug has erroneously developed a reputation for giving users a feeling of being “high”.
In some cases, doctors may prescribe Robaxin as a supplement to opiate withdrawal medications such as Suboxone to relieve muscle spasms and muscle cramping.
Overdose of methocarbamol is often in conjunction with alcohol or other CNS depressants. Overdose symptoms may include some or all of the following:
- blurred vision
Deaths have been reported with an overdose of methocarbamol alone or in the presence of other CNS depressants, alcohol or psychotropic drugs.
Fexmid and Amrix are now the brand names for Flexeril in the U.S. Although both drugs are muscle relaxants, they cause different side effects. For example, Fexmid and Amrix cause dry mouth, abdominal pain, acid reflux and constipation. Robaxin does not cause these symptoms.
- Amrix and Fexmid are chemically related to tricyclics, an older class of antidepressants prescribed for depression, anxiety and panic disorder.
In addition, if you abruptly stop taking Amrix or Fexmid, you may experience withdrawal symptoms like weakness, nausea and headaches. Cessation of Robaxin will not cause withdrawal symptoms.
Soma is a strong muscle relaxant that is pharmacologically and structurally related to an addictive metabolite.
Once widely prescribed to reduce anxiety, Soma has been replaced by benzodiazepines such as Valium and Xanax due to these newer anxiolytics having a lower risk of side effects and toxicity.
Soma is listed as a Schedule IV controlled drug in the U.S. and presents an addiction risk similar to benzodiazepines.
This drug does have the potential for abuse and dependency. And, the fact that it is “uncontrolled” makes it more susceptible to misuse. Comparison studies involving diphenhydramine and lorazepam (a benzodiazepine) has shown that this drug induces an increased “liking” response from subjects due to its sedative effects. However, a higher than normal doses, this drug can cause depression, anxiety and agitation. The study went on to say “The results showed that both lorazepam and methocarbamol produced statistically significant dose-related increases in subjects’ ratings of drug effect and liking.
- Researchers consider this it to hold an abuse profile much weaker than most benzodiazepines.
When this drug is combined with acetaminophen, it is sold under the trade names “Tylenol Body Pain Night” and “Robaxacet”. Combining it with ibuprofen is called Robax Platinum and add to acetylsalicylic acid is known as Robaxisal.
