Cyclobenzaprine and Back Pain: A Meta-analysis Clinical Pharmacy and Pharmacology JAMA Internal Medicine

Some muscle relaxers start working within 30 minutes of taking them, and the effects can last anywhere from 4 to 6 hours. In patients with CNS depression, early intubation is advised because of the potential for abrupt deterioration. Seizures should be controlled with benzodiazepines or, if these are ineffective, other anticonvulsants (e.g. phenobarbital, phenytoin). Physostigmine is not recommended except to treat life-threatening symptoms flexeril cut in half that have been unresponsive to other therapies, and then only in close consultation with a poison control center. The plasma concentration of cyclobenzaprine is increased in the elderly (see CLINICAL PHARMACOLOGY, Pharmacokinetics, Elderly). The elderly may also be more at risk for CNS adverse events such as hallucinations and confusion, cardiac events resulting in falls or other sequelae, drug-drug and drug-disease interactions.

• Both of them are used for pain relief but have different mechanisms.
• Each type of prescription muscle relaxer has different possible side effects.
• Check with your doctor before taking any of the above while you are using this medicine.
• No matter what kind of muscle relaxer you take, it is common to have side effects.

Yes, prescription muscle relaxers can make you sleepy due to how they affect your central nervous system. Because of this, you should be cautious about operating heavy machinery, such as driving a car, or making important decisions while taking these medications. In general, antispastic medications act on your spinal cord or skeletal muscle directly to improve muscle tightness (hypertonicity) and involuntary spasms.

The perceived benefits of taking any medication should always outweigh the potential risks. RxList does not provide medical advice, diagnosis or treatment. You may also report negative side effects of prescription drugs to the FDA by visiting the FDA MedWatch website or calling FDA-1088. Ultram is contraindicated in patients receiving MAO inhibitors or who have used them within the previous 14 days.

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.

International Patients

Cyclobenzaprine is a tricyclic molecule discovered in 1956 that is structurally related to amitriptyline and imipramine. Since Flexeril is a muscle relaxant that shows the depressive activity of the CNS, it is not recommended to drive or do any dangerous activity under the influence of Flexeril. Combining this drug with alcohol may worsen the side effects you may observe. Modifying the drug dose without consulting a physician to amplify its impact is also not recommended.

Use of Flexeril for periods longer than two or three weeks is not recommended. Thirteen articles18,21,24,25,30-37 reported a global measure of symptom improvement. While articles reported this outcome at various time points, only global improvement at the end of the trials was present in a sufficient number of studies to be considered reliable enough for this analysis. Nine24,25,30,31,33-37 of these ratings of improvement were physician rated, and 118 was patient rated. Standardized mean differences in patient response to cyclobenzaprine hydrochloride compared with placebo on 5 different domains of back pain. Squares represent the sample size; horizontal lines, the respective 95% confidence intervals of the effect size.

Symptoms of overdose may include the following:

Flexeril (cyclobenzaprine) and Ultram (tramadol) are used to treat back pain. The easiest way to lookup drug information, identify pills, check interactions and set up your own personal medication records. Avoid driving or hazardous activity until you know how cyclobenzaprine will affect you.

Additional potential side effects of this drug include fatigue, headache, nervousness, dilated pupils, hallucinations, increased heart rate, and digestion issues (1, 8). Cyclobenzaprine (sometimes branded as Flexeril) is an antispasmodic, FDA-approved medication for the treatment of acute musculoskeletal pain (8). It belongs to a group of medications called tricyclic antidepressants. Cyclobenzaprine should be combined with rest and other conservative interventions in the treatment of acute muscle spasm. Conclusions Cyclobenzaprine is more effective than placebo in the management of back pain; the effect is modest and comes at the price of greater adverse effects. The effect is greatest in the first 4 days of treatment, suggesting that shorter courses may be better.

Muscle Relaxant Medications List

When you are taking this medicine, it is especially important that your healthcare professional know if you are taking any of the medicines listed below. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive. Analysis of the data from controlled studies shows that FLEXERIL produces clinical improvement whether or not sedation occurs. In a pharmacokinetic study of sixteen subjects with hepatic impairment (15 mild, 1 moderate per Child-Pugh score), both AUC and Cmax were approximately double the values seen in the healthy control group. Based on the findings, FLEXERIL should be used with caution in subjects with mild hepatic impairment starting with the 5 mg dose and titrating slowly upward. Due to the lack of data in subjects with more severe hepatic insufficiency, the use of FLEXERIL in subjects with moderate to severe impairment is not recommended.

Baclofen can be administered orally or intrathecally through a surgically inserted spinal cord pump. Intrathecal baclofen is generally considered if a patient demonstrates adverse effects or no response to oral delivery (2). In this article, we’ll explore how muscle relaxants work, compare two specific relaxants (cyclobenzaprine, sold under the brand Flexeril, versus baclofen), and offer advice for how to decide which one would be better for your pain.
