What are the main differences between Robaxin and Flexeril?
Robaxin, known by its generic name methocarbamol, was released on the market in the 1960s. While its exact mechanism of action is unknown, Robaxin is believed to relieve discomfort through its sedative effects. It does not directly affect muscle contractions.
Robaxin is available as a brand name or generic medication. It comes as an injection as well as a 500 mg or 750 mg oral tablet. Those who are prescribed Robaxin tablets need to take two or three tablets four times per day, initially. Then, one or two tablets three to four times per day or more is recommended.
Flexeril was initially approved by the FDA in the 1970s. It primarily works on the brain stem and spinal cord in the CNS, which helps reduce motor activity. Flexeril is also structurally similar to tricyclic antidepressants and has similar side effects such as dry mouth and sedation.
Flexeril is commonly known by its generic name cyclobenzaprine. Brand-name Flexeril has been discontinued; however, cyclobenzaprine is available in two other brand names: Amrix (extended-release) and Fexmid (immediate-release). The extended-release tablet can be taken once per day.

Conditions treated by Robaxin and Flexeril
Robaxin and Flexeril are FDA approved to treat discomfort or muscle spasms from acute musculoskeletal conditions as well as tetanus.
Robaxin or Flexeril are usually prescribed to treat musculoskeletal pain such as neck pain. Both drugs are also often used to treat low back pain, a common problem in adults in the US. Up to 80% of adults experience low back pain at some point in their lives.
Flexeril has also been studied to treat fibromyalgia, a chronic condition characterized by muscle pain all over the body. Those with fibromyalgia may experience widespread muscle pain as well as problems with sleep, fatigue, and mood. According to a meta-analysis of five clinical trials, cyclobenzaprine was found to improve sleep and pain in patients with fibromyalgia over a period of up to 24 weeks.
Is Robaxin or Flexeril more effective?
Robaxin and Flexeril are effective treatments for treating musculoskeletal pain and muscle spasms. The more effective drug is the one that works best for your specific case.
Flexeril is one of the most studied muscle relaxants; thus, it has more supporting evidence for its effectiveness. In a systematic review, it was found that, in general, muscle relaxants are comparable in effectiveness. This review included other muscle relaxants such as metaxalone, baclofen, tizanidine, orphenadrine, and chlorzoxazone.
In a head-to-head trial between methocarbamol and cyclobenzaprine, there was no significant difference in muscle spasms or tenderness. However, patients experienced slightly better improvements in local pain with cyclobenzaprine (48% vs. 40%). Cyclobenzaprine was also found to produce more somnolence or drowsiness (58% vs. 10%).
Cyclobenzaprine has been compared to Valium (diazepam) and Soma (carisoprodol) in clinical trials. Cyclobenzaprine was similarly effective to these drugs for treating acute low back pain.
Consult a healthcare provider for medical advice to find the best treatment options for you. After a complete assessment from a doctor, one drug may be preferred depending on your overall medical history.
Common side effects of Robaxin vs. Flexeril
The most common side effects of Robaxin and Flexeril are drowsiness, dizziness, and headache. Flexeril may be associated with more drowsiness compared to Robaxin. Because of its anticholinergic properties, Flexeril can also cause dry mouth.
Both Robaxin and Flexeril can cause some degree of fatigue or nausea.
More serious side effects include hypersensitivity reactions. These allergic reactions can manifest as trouble breathing, severe rash, and swelling. Seek immediate medical attention if you experience these adverse effects.
