Several measures of the sensitivity of the meta-analysis results to various assumptions were conducted. 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. The efficacy of FLEXERIL 5 mg was demonstrated in two seven-day, double-blind, controlled clinical trials enrolling 1405 patients.

Interactions

Methocarbamol and metaxalone are less sedating, although effectiveness evidence is limited. Adverse effects, particularly dizziness and drowsiness, are consistently reported with all skeletal muscle relaxants. The potential adverse effects should be communicated clearly to the patient.

• Using Flexeril with other drugs that make you drowsy can worsen this effect.
• As a result, the cyclobenzaprine high can actually end up leading to the development of addictions to other drugs as well.
• A test for the relative influence of each individual study on the results was determined by sequentially dropping individual studies and calculating summary measures.
• Cyclobenzaprine (Flexeril) is structurally similar to TCAs and, as such, demonstrates significant anticholinergic side effects.

Another study30 explored the potential biasing effect of higher rates of adverse effects by stratifying patient results by the presence or absence of adverse effects. This study30 found the rate of improvement between both groups to be equal, and concluded that the potential unmasking of treatment group by adverse effects had no impact on patient outcomes. Skeletal muscle relaxants are prescription medications commonly used to treat muscle pain and muscle spasms. If you have back pain or have suffered a strain or sprain, your healthcare provider may offer you a skeletal muscle relaxant such as methocarbamol (Robaxin) or cyclobenzaprine (Fexmid, Amrix). Among these 14 trials, 11 found benefit and 3 did not, although only 8 were placebo controlled.

How to use Flexeril Tablet

Because of its long elimination half-life, dose tapering should be unnecessary after short term use.5,8 We identified no case reports of withdrawal effects. Cyclobenzaprine is a tricyclic molecule discovered in 1956 that is structurally related to amitriptyline and imipramine. It’s important to thoroughly inform your doctor about all of your medical conditions because muscle relaxants might not be suitable for certain diseases and conditions. Flexeril (generic name cyclobenzaprine) was developed in the 1970s.

The tablet is usually taken with or without food three times a day. The extended-release capsule is usually taken with or without food once a day. Do not take this drug for more than 3 weeks without talking to your doctor.

How long does it take for cyclobenzaprine to work?

This can be harmful or prevent the drug from working well. Cyclobenzaprine oral tablet may cause drowsiness and dizziness. This is more likely to happen in the few hours after you take it. Cyclobenzaprine may be used as part of combination therapy. This means you may need to take it with other medications.

Systematic reviews and meta-analyses support using skeletal muscle relaxants for short-term relief of acute low back pain when nonsteroidal anti-inflammatory drugs or acetaminophen are not effective or tolerated. Comparison studies have not shown one skeletal muscle relaxant flexeril review to be superior to another. Cyclobenzaprine is the most heavily studied and has been shown to be effective for various musculoskeletal conditions. The sedative properties of tizanidine and cyclobenzaprine may benefit patients with insomnia caused by severe muscle spasms.

Robaxin is available as an oral tablet of 500 mg or 750 mg. 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. Robaxin is the brand name of the generic medication called methocarbamol.

Abstracted data included setting, country of origin, treatment characteristics (dose, duration, and follow-up), demo graphics, number of participants enrolled, follow-up losses, adverse effects, and outcomes. Outcomes were extracted as either dichotomous or continuous variables (or both), depending on how they were reported in the studies. 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. Cyclobenzaprine has not been tested in pediatric patients younger than 15 years of age. The elderly may be at a higher risk for adverse events, including hallucinations and confusion, cardiac events and drug interactions.
