Cyclobenzaprine and back pain: a meta-analysis
Methocarbamol typically needs to be taken up to 4 times a day, whereas cyclobenzaprine extended-release capsules offer the convenience of once-a-day dosing. Keep in mind that regular cyclobenzaprine tablets may require dosing of up to 3 times a day. Stopping muscle relaxants suddenly can lead to withdrawal symptoms. Anyone with a history of substance abuse should mention this medical history to their doctor.
- Zanaflex and Flexeril can enhance their effects and lead to increased dizziness and sedation.
- Generic Zanaflex is typically covered by most Medicare and insurance plans.
- Muscle relaxants with CNS depressant effects can increase the risk of dizziness, falls, and serious injury in the elderly.
- In patients with mild to moderate hepatic impairment, peak plasma concentration and AUC following administration of immediate-release tablets are twice the values in healthy individuals.
Zanaflex is a newer drug FDA-approved for muscle spasticity due to multiple sclerosis and spinal cord injuries. Flexeril is an older drug that has been more heavily studied for musculoskeletal pain and spasms. The better drug is the one that works best for your specific condition. Zanaflex, or tizanidine, is a muscle relaxant used to treat muscle spasticity due to multiple sclerosis and spinal cord injury. It works by blocking signals between motor nerves to relax muscle tone.
The most common side effects of Zanaflex include dry mouth, drowsiness, dizziness, muscle weakness or fatigue, and constipation. Other reported side effects include urinary tract infections (UTIs) and involuntary movements (dyskinesia). Zanaflex and Flexeril are both effective drugs for muscle spasms and muscle pain. Their use depends on which one is more suitable on a case-by-case basis.
Frequently asked questions about Robaxin vs. Flexeril
Consult a healthcare provider to determine the best treatment option for you. Flexeril (What is Flexeril?) is a brand-name drug originally FDA-approved in 1977. The generic version of Flexeril, cyclobenzaprine, is widely available. Flexeril is structurally similar to tricyclic antidepressants and primarily works in the central nervous system (CNS). It helps reduce muscle hyperactivity through actions on the gamma- and alpha-motor systems.
Further classified as antispasmodic agents, Robaxin and Flexeril are effective for treating acute, painful musculoskeletal conditions that cause discomfort and muscle spasms. They also have similar side effects such as drowsiness and dizziness. Taking muscle relaxants with these drugs can cause increased side effects like drowsiness and dizziness. Tizanidine may be preferred for muscle spasms caused by multiple sclerosis, cerebral palsy, and spinal cord injury. Cyclobenzaprine is used along with physical therapy and rest to relieve pain and muscle spasms. It is a muscle relaxant indicated for acute, painful musculoskeletal conditions such as neck or back pain.

In fact, Flexeril is detectable in a urine sample for several days after consumption. Following administration of a single 15- or 30-mg dose (as extended-release capsules), peak plasma concentrations achieved in 7–8 hours. Following multiple-dose administration (30 mg once daily for 7 days as extended-release capsules), 2-5-fold accumulation in steady-state plasma concentrations observed. Insufficient evidence to indicate whether cyclobenzaprine enhances the effects of aspirin or other analgesics, or vice versa, in the management of painful musculoskeletal conditions. When butalbital is used for a long time, it may become habit-forming, causing mental or physical dependence. However, people who have continuing pain should not let the fear of dependence keep them from using narcotics to relieve their pain.
What is Robaxin?
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. 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 can interact with serotonergic drugs like antidepressants and MAO inhibitors.
The other dosage form of this medicine is an injection solution into a muscle or into a vein. Robaxin needs to be taken three to four times a day to provide relief from muscle pain and muscle spasms. Flexeril is also covered by most Medicare and insurance plans when it’s prescribed as a generic. Immediate-release tablets are commonly prescribed to be taken multiple times per day.
It’s critical that patients follow the dosage prescribed by their physician because there’s a risk of overdose if cyclobenzaprine is taken in excess. The drug resulted in four deaths in the United States in 2016, according to the American Association of Poison Control Centers. Skeletal muscle relaxants like cyclobenzaprine and methocarbamol can cause dizziness and drowsiness. Therefore, you should wait and see how these medications affect you before driving a motor vehicle or operating machinery. Some people prefer Fexmid and Amrix over Robaxin because it is dosed once a day rather than 3 to 4 times a day. On the other hand, they can cause more adverse effects such as dry mouth and drowsiness.
In fact, approximately 11.5 million Americans reported abusing prescription pain relievers at least once in a 12-month period. Increased frequency and severity of adverse effects (with or without concomitant drug therapy). Cyclobenzaprine is structurally and pharmacologically related to tricyclic antidepressants. Among the most dreaded toxicities linked with cyclical antidepressants, overdoses buy flexeril with no perscription affect fast-acting sodium channels in the cardiac conduction system. Cyclical antidepressants block the cardiac sodium channel and cause prolongation of cardiac depolarization, which manifests as QRS widening on electrocardiograms. There is also evidence that cyclical antidepressants may decrease the seizure threshold by interfering with chloride conductance on the GABA receptor.
