Muscle Relaxers: How They Work, Common Types, Side-Effects, Abuse
They belong to two different drug classes – muscle relaxant and benzodiazepine, respectively. The only salient difference is that Valium has a higher potential to cause drug dependency than Flexeril. However, your physician can better decide which drug is better for your back pain. The drug Cyclobenzaprine, sold under the brand Flexeril, is structurally very similar to a class of Antidepressants called Tricyclic Antidepressants.
A long-acting formulation of cyclobenzaprine has been introduced and is believed by some clinicians to have a lower side effect profile than the immediate-release formulation of this drug. If you are not able to swallow the extended-release capsule whole, mix the contents of the capsule with applesauce. After you eat the mixture, take a drink, and swish and swallow to make sure that you have received all the medication.
A test for the relative influence of each individual study on the results was determined by sequentially dropping individual studies and calculating summary measures. We explored several sources of heterogeneity, including year of publication, type of syndrome (acute vs chronic back pain), study quality scores, and duration and dose of therapy using metaregression. Likelihood of experiencing overall improvement in back pain by the end of the study among patients treated with cyclobenzaprine hydrochloride compared with placebo. Squares represent the sample size; horizontal lines, the respective 95% confidence intervals of the odd ratios. Further research is needed to conclusively address this question.

By inhibiting these signals, cyclobenzaprine reduces or even eliminates muscle spasms. Take your prescribed dose as indicated by your health care provider. The maximum dosage is 1 or 2 tablets every 4 to 6 hours, as needed for pain relief. Do not take more than your prescribed dose and do not take more than 8 tablets per day. For most patients, the recommended dose of Flexeril is 5 mg three times a day. Based on individual patient response, the dose may be increased to 10 mg three times a day.
- Short duration studies show that cyclobenzaprine is also effective in reducing pain from fibromyalgia (10).
- However, more severe cases, these primary treatments may prove insufficient.
- The acute oral LD50 of FLEXERIL is approximately 338 and 425 mg/kg in mice and rats, respectively.
- It works by blocking nerve impulses (or pain sensations) that are sent to your brain.
- These patients are generally more susceptible to drugs with potentially sedating effects, including cyclobenzaprine.
This should include large volume gastric lavage followed by activated charcoal. If consciousness is impaired, the airway should be secured prior to lavage and emesis is contraindicated. why is flexeril discontinued In order to protect against the rare but potentially critical manifestations described above, obtain an ECG and immediately initiate cardiac monitoring.
Before taking this medicine
These medications make it hard to think and function normally, even if you take a low dose, so combining them with alcohol can increase your risk of an accident. No matter what kind of muscle relaxer you take, it is common to have side effects. Some muscle relaxants, however, can have potentially serious side effects, like liver damage. Your doctor will work with you to find the medication that makes the most sense for your situation.
The most common side effects of baclofen are muscle weakness, confusion, vertigo, nausea, and momentary sedation or drowsiness (2, 4, 11). Additional potential side effects of this drug include low blood pressure, swelling, shortness of breath, and insomnia among many other reported adverse effects (2). These side effects are most common with oral baclofen and less common with intrathecal baclofen because the drug is injected directly into the fluid surrounding the brain and spinal cord (11). The most common adverse effects of cyclobenzaprine are drowsiness, dry mouth, dizziness, and confusion (8).
Adverse effects will be common, experienced in more than half of the patients, with 20% experiencing drowsiness. The treatment effect is greatest early, suggesting that a short course may be preferable, although even at 2 weeks patients given cyclobenzaprine had slightly better results on all 5 domains of back pain. Studies to determine the optimum combination and duration of treatment in the management of acute back pain are needed.
We found that there would have to be 947 studies finding no global improvement with the use of cyclobenzaprine and between 201 and 786 studies (Table 2) finding no benefit in our 5 specific back pain measures to negate our results. The medicine treats the condition by providing intermittent relief to the pain caused due to the spasms. It blocks the pathway of neurotransmitters that are responsible for the sensation of pain. It relaxes only the muscles and not the actual causative nerves behind the pain. For best results, doctors recommend combining the use of Flexeril with rest and physical therapy. Although antispastics and antispasmodics are both types of skeletal muscle relaxants, they have specific and different uses.
