Flexeril Oral: Uses, Side Effects, Interactions, Pictures, Warnings & Dosing

Modifying the drug dose without consulting a physician to amplify its impact is also not recommended. When certain drugs are used with cyclobenzaprine, they may cause more severe side effects such as increased drowsiness or sedation. A person should ask their doctor whether it is safe to combine another medication with cyclobenzaprine and take care not to operate any machinery while taking it. Sometimes people will even have a heart attack or develop seizures.

  • Cyclobenzaprine medications are not DEA Scheduled drugs and, therefore, the potential for misuse and dependence with Flexeril is considered to be relatively low.
  • The technical name of the active compound in Flexeril is cyclobenzaprine which can be found in a variety of different products.
  • In order to protect against the rare but potentially critical manifestations described above, obtain an ECG and immediately initiate cardiac monitoring.
  • The only salient difference is that Valium has a higher potential to cause drug dependency than Flexeril.

Pharmacologic similarities among the tricyclic drugs require that certain withdrawal symptoms be considered when FLEXERIL is administered, even though they have not been reported to occur with this drug. Abrupt cessation of treatment after prolonged administration rarely may produce nausea, headache, and malaise. The following list of adverse reactions is based on the experience in 473 patients treated with FLEXERIL 10 mg in additional controlled clinical studies, 7607 patients in the post-marketing surveillance program, and reports received since the drug was marketed. The overall incidence of adverse reactions among patients in the surveillance program was less than the incidence in the controlled clinical studies. For most patients, the recommended dose of FLEXERIL is 5 mg three times a day.

Side Effects

An overlay of cyclobenzaprine with a member of each is at right. Do not drive, use machinery, or do anything that needs mental alertness until you know how this medication affects you. Do not stand or sit up quickly, especially if you are an older patient. This medicine may be used for other purposes; ask your health care provider or pharmacist if you have questions. Along with its needed effects, a medicine may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention.

Flexeril abuse can also end up leading to dangerously slow respiration. When Flexeril and alcohol are mixed, however, these qualities can actually end up overlapping, making the potentially fatal risk of low respiration even more likely to occur. The alcohol also increases the side effects of cyclobenzaprine. This includes dizziness, difficulty thinking, and drowsiness.

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. Using saturation radioligand binding, we also demonstrate that cyclobenzaprine binds to the H1R in a noncompetitive manner. 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. Using saturation radioligand binding, we also demonstrate that cyclobenzaprine binds to the H1R in a non-competitive manner. Whether cyclobenzaprine is superior to other drugs for the management of acute myofascial strain is unclear and it usually adds more side effects with little therapeutic gain (Turturro et al 2003).

Drug Abuse

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. Other drugs may interact with cyclobenzaprine, including prescription and over-the-counter medicines, vitamins, and herbal products.

Methocarbamol typically needs to be taken up to 4 times a day, whereas cyclobenzaprine extended-release capsules offer the convenience of once-a-day dosing. Keep in mind that regular cyclobenzaprine https://flexeril.live tablets may require dosing of up to 3 times a day. The combination of Flexeril and alcohol can cause serious problems in the central nervous system, the consequences of which may end up being fatal.

This timeline is appropriate for an immediate-release formulation. In the case of an extended-release formulation, the effects last for up to 24 hours. It is not controlled under the Controlled Substances Act (CSA), either.

In preclinical research, cyclobenzaprine reduced skeletal muscle hyperactivity. Research indicates that it primarily acts within the central nervous system in the brain stem. Cyclobenzaprine is a centrally acting skeletal muscle relaxant structurally related to tricyclic antidepressants. Cyclobenzaprine is a tricyclic amine salt that works in the central nervous system (CNS) as a depressant that reduces muscle hyperactivity. Clinical indications for cyclobenzaprine are described below. Concomitant use of monoamine oxidase (MAO) inhibitors or within 14 days after their discontinuation.

Other uses for this medicine

Your doctor may choose to speak to you about Flexeril, a commonly used muscle relaxant in cases of persistent pain. Cyclobenzaprine can increase the effects of CNS depressants, such as alcohol, opioids, allergy medications, and sleeping pills. If a person is prescribed cyclobenzaprine, they should make sure their health care provider knows all medications they are taking (including over-the-counter medications), as well as if they drink alcohol or use other drugs. This enables the provider to evaluate for any potential interactions and helps them keep the patient safe.
