Muscle Relaxers: What They Are, Uses, Side Effects & Types

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.

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 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.

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.

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.

What are the types of muscle relaxers?

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 what color are flexeril pills 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.

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.

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. Any missing drug warnings or information does not in any way guarantee the safety, effectiveness, or the lack of adverse effects of any drug. The drug information provided is intended for reference only and should not be used as a substitute for medical advice.

• Ask your doctor before using opioid medication, a sleeping pill, a muscle relaxer, or medicine for anxiety or seizures.
• Cyclobenzaprine caused slight to moderate increase in heart rate in animals.
• Intrathecal baclofen is generally considered if a patient demonstrates adverse effects or no response to oral delivery (2).
• Any issues with the delivery system can induce withdrawal from the drug in patients who have been using baclofen for more than two months (2).
• These drugs do not act directly on the muscles; rather they act centrally (in the brain) and are more of a total body relaxant.

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.

It is available in the form of tablets and extended-release capsules. Cyclobenzaprine is a centrally acting skeletal-muscle relaxant, claimed to be effective in providing relief of muscle spasm, pain and tenderness, and in reducing the limitations imposed thereby on normal daily activities. It is structurally similar to the tricyclic antidepressants and adverse effects similar to those seen with the tricyclic antidepressants are therefore to be expected.

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.
