Cyclobenzaprine: MedlinePlus Drug Information

Because of limited comparable effectiveness data, choice of agent should be based on side-effect profile, patient preference, abuse potential, and possible drug interactions. Cyclobenzaprine is a tricyclic dimethylpropanamine skeletal muscle relaxant, which is used clinically to decrease muscle spasm and hypercontractility, as well as acute musculoskeletal pain. Although the absolute mechanism of action of cyclobenzaprine remains elusive, it is known to mediate its effects centrally, via inhibition of tonic somatic motor function, likely through modulation of noradrenergic and serotonergic systems. While cyclobenzaprine is effective as a muscle relaxant, greater than 30% of patients experience drowsiness and sedative/hypnotic effects, yet, the mechanisms that cause this adverse effect is also undescribed. Here, for the first time, we present data that demonstrate that cyclobenzaprine exhibits low nanomolar affinity for the cloned human H1R, as well as that expressed in both rat and mouse brain.

Meditation and mindfulness are two great ways to destress, slow down racing thoughts, and reduce anxiety while also relieving muscle tension – especially in the neck, back, and shoulders. Meditate for 5 to 10 minutes each morning, before going to bed, or both. Journaling at night can also help purge anxious thoughts and better prepare you for sleep.

Drugs you should not take with cyclobenzaprine

Your doctor may decide not to treat you with this medication or change some of the other medicines you take. Analysis of the data from controlled studies shows that FLEXERIL produces clinical improvement whether or not sedation occurs. Other potential effects of overdosage include any of the symptoms listed under ADVERSE REACTIONS. It is not known whether this drug is excreted in human milk. Because cyclobenzaprine is closely related to the tricyclic antidepressants, some of which are known to be excreted in human milk, caution should be exercised when FLEXERIL is administered to a nursing woman. Tricyclic antidepressants have been reported to produce arrhythmias, sinus tachycardia, prolongation of the conduction time leading to myocardial infarction and stroke.

Cyclobenzaprine’s plasma concentrations average 40% higher in the elderly, making these patients more at risk of the drug’s harmful effects. The drug is also eliminated more slowly in this age group. If you’re taking Flexeril non-medically for a high—with or without other drugs—treatment for substance abuse can prevent you from suffering a dangerous flexeril weight gain overdose. Extreme stress can cause increased muscle tension and worsen your current pain or discomfort. Finding new ways to destress and relax can help ease muscle strain while also reducing anxiety and improving your mental health. The less stressed you are, the more relaxed you become and the easier you may find it to fall asleep at night.

Overdose symptoms may include severe drowsiness, vomiting, fast heartbeats, tremors, agitation, or hallucinations. Flexeril is a muscle relaxant and works by blocking the pathways of the neurotransmitters that signal pain. It is not an anti-inflammatory drug and does not reduce any inflammation to provide muscle relief. Both of them are used for pain relief but have different mechanisms. In most cases, it is advised not to take an anti-inflammatory drug and a muscle relaxant simultaneously, as they might be contra-indicated. Laguna Treatment Hospital—our rehab facility in Orange County, CA—utilizes effective, evidence-based approaches through a variety of levels of addiction treatment that can help you or your loved one get sober and remain in recovery.

I did drink some alcohol when it was offered to me, and the strangest thing happened. I was sitting on the sofa in the living room, and after some time, I couldn’t move my legs. They didn’t hurt at all, but it was like the connection between my legs and my brain had been severed. I slept there until the morning, at which point, I was still groggy, but at least I could move my legs.

This can help patients avoid the discomfort of withdrawing from cyclobenzaprine. Cyclobenzaprine is a drug prescribed to treat pain and discomfort. This page will go over its side effects, drug interactions, and treatment for misuse. Taking this drug with an MAOI or within 14 days of stopping an MAOI could increase your risk of serious side effects. Another telltale sign of Flexeril addiction is abusing the medication in combination with another substance to produce a greater sense of euphoria. Alcohol is commonly abused alongside muscle relaxers like Flexeril because the substances amplify each others’ effects, causing the individual to experience a more intense sedation or high.

The Hill slope was similar to that of diphenhydramine and characteristic of antagonist binding to a uniform population of sites of a GPCR (Hall and Langmead, 2010). Although diphenhydramine also fully displaced [3H]-mepyramine from the H1R, it did so with 2.3-fold less affinity (Ki 7.4 ± 0.8) (Fig. 1A; Table 1). This difference in affinity was also evident at both the mouse and rat cortical H1R, where cyclobenzaprine was 5-fold (9.2 ± 2.5 nM vs. 45.6 ± 8.6 nM) and 7-fold (7.1 ± 0.5 nM vs. 52.7 ± 13.4 nM) more potent than diphenhydramine, respectively (Fig. 1A; Table 1). Hill slopes for cyclobenzaprine were similar to diphenhydramine in both mouse (−0.93 ± 0.04 and −0.90 ± 0.03, respectively) and rat (−1.1 ± 0.02 and −0.96 ± 0.1, respectively) H1R (Table 1).

If it is, you can begin to take the necessary steps that you’ll need to recover.
Concomitant use of monoamine oxidase (MAO) inhibitors or within 14 days after their discontinuation.
Cyclobenzaprine also has some sedative effects which may result in sleepiness and fatigue.
Give your health care provider a list of all the medicines, herbs, non-prescription drugs, or dietary supplements you use.
Multiple drug ingestion (including alcohol) is common in deliberate cyclobenzaprine overdose.
The DEA found that nearly 25 million prescriptions were given out for cyclobenzaprine, the active ingredient in Flexeril.

To find out how this drug might interact with something else you’re taking, talk with your doctor or pharmacist. If these effects are mild, they may go away within a few days or a couple of weeks. If they’re more severe or don’t go away, talk with your doctor or pharmacist.

Flexeril High: Why This Muscle Relaxer is Creating Dependency

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. Since overdosage is often deliberate, patients may attempt suicide by other means during the recovery phase.
