Flexeril Addiction And Abuse

The most common adverse reactions to cyclobenzaprine are somnolence, dry mucous membranes, dizziness, and confusion. Less commonly, tachycardia, dysarthria, disorientation, and hallucinations have been reported [2]. Significance Statement Cyclobenzaprine, a clinically used muscle relaxant that is strongly linked to sedation, demonstrates high affinity non-competitive antagonism at the histamine H1 receptor. This effect likely modulates the high degree of sedation patients experience.

Flexeril works on the central nervous system to reduce motor activity or muscle contractions, thus, relieving muscle spasms. Cyclobenzaprine is structurally and pharmacologically related to tricyclic antidepressants. Among the most dreaded toxicities linked with cyclical antidepressants, overdoses affect fast-acting sodium channels in the cardiac conduction system. Cyclical antidepressants block the cardiac sodium channel and cause prolongation of cardiac depolarization, which manifests as QRS widening on electrocardiograms. There is also evidence that cyclical antidepressants may decrease the seizure threshold by interfering with chloride conductance on the GABA receptor.

Adverse Effects

Concomitant use of monoamine oxidase (MAO) inhibitors or within 14 days after their discontinuation. Hyperpyretic crisis, seizures, and deaths have occurred in patients receiving cyclobenzaprine (or structurally similar tricyclic antidepressants) concomitantly with MAO inhibitor drugs. Acute recovery phase of myocardial infarction, and patients with arrhythmias, heart block or conduction disturbances, or congestive heart failure and hyperthyroidism. Skeletal muscle relaxants are prescription medications commonly used to treat muscle pain and muscle spasms.

Muscle relaxants account for approximately 18.5% of all prescriptions written for chronic back pain in the United States[2]. The drug Cyclobenzaprine, sold under the brand Flexeril, is structurally very similar to a class of Antidepressants called Tricyclic Antidepressants. Flexeril is commonly prescribed to induce pain relief from muscle spasms and improve motor skills, sleep, and energy levels by generating pain relief. These feelings may potentially be a cause for misuse of Flexeril and lead to addictive effects. Professionals generally consider Flexeril to be nonaddictive; however, there is evidence that Flexeril addiction is possible. Flexeril depresses the central nervous system, an effect some find desirable, which can lead to misuse.

Which is cheaper – cyclobenzaprine or methocarbamol?

In children 2 to 7 years old, the dose is 10 to 15 mg/day, divided in two to three doses. The dose can be escalated every 3 days by 5 mg to a maximum dose of 40 mg/day. In children older than 8 years of age, the maximum dose is 60 mg/day. Baclofen is one of a few medications approved for intrathecal administration via implanted pumps and is usually administered to children with spasticity (e.g., cerebral palsy, spinal cord injury).

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. Please continue reading to learn about the similarities and differences between methocarbamol and cyclobenzaprine, including how they work, their side effects, drug interactions, cost, and more. Elderly patients seem to tolerate cyclobenzaprine less and may develop hallucinations as well as significant anticholinergic side effects, such as sedation. The use of significant lower dosing schedules in elderly patients may be prudent. He was aggressively hydrated, cardiac monitoring showed tachycardia which resolved on day 3 of his admission.

  • In severe overdose, ventricular arrhythmias and seizures may require MICU-level of care under the supervision of a critical care physician.
  • Withdrawal symptoms have been noted with the discontinuation of chronic cyclobenzaprine use.
  • For best results, doctors recommend combining the use of Flexeril with rest and physical therapy.
  • A new, controlled-release formulation of the drug is now available and appears to have a more favorable side-effect profile when compared with the immediate-release formulation.
  • Cyclobenzaprine is a weak inhibitor of presynaptic norepinephrine and serotonin.

In two case reports, the authors described patients who quickly developed serotonin syndrome after initiating cyclobenzaprine in the short term. In both cases, the patients took serotonergic medications (phenelzine and duloxetine) before starting cyclobenzaprine.[21]Clinicians should also monitor for vital signs, as cyclobenzaprine can cause reflex tachycardia. Sometimes, cyclobenzaprine is prescribed off-label to treat fibromyalgia, although it is considered a second-line treatment for that condition.

Get Help for Cyclobenzaprine Abuse

There are anecdotal reports that cyclobenzaprine or Flexeril has been abused for recreational purposes, as it can potentially lead to an intense relaxation similar to narcotics. The drug can disrupt neurotransmitter action in the brain, which may increase the euphoric feeling on a short-term basis but can also cause brain damage and cognitive difficulties after long-term abuse. Cyclobenzaprine is believed to act on gamma and alpha neurons and their firing, to reduce muscle tension or spasms. Cyclobenzaprine is the is flexeril considered an nsaid generic name for a muscle relaxant, prescribed in the US under brand names like Amrix, Fexmid, FusePaq Tabradol, and, most popularly, Flexeril. The medication treats tense, sore, and stiff muscles after a strain, sprain, or other muscle injury; however, it is intended to work in combination with physical therapy, exercise, and rest to help the affected area heal. Another telltale sign of Flexeril addiction is abusing the medication in combination with another substance to produce a greater sense of euphoria.

Muscle relaxants such as Cyclobenzaprine (Flexeril) and Orphenadrine Citrate (Norflex) have also been studied in the treatment of fibromyalgia. In a study of 120 fibromyalgia patients, those receiving Cyclobenzaprine (10 to 40 mg) over a 12 week period had significantly improved quality of sleep and pain score. Interestingly, there was also a reduction in the total number of tender points and muscle tightness.

By slowing down neuron impulses, cyclobenzaprine stops skeletal muscle spasms, making it a good short-term treatment for minor, but painful, injuries to this system. Since the drug acts on the brain instead of the spinal cord or muscles, it is a good treatment for overall pain problems. Baclofen is one of the most powerful centrally acting muscle relaxants. It is usually indicated in patients with spasticity such as cerebral palsy or multiple sclerosis.
