Can You Overdose on Flexeril? Side Effects & Symptoms

It was almost as if it would be too difficult for me to even move. About three hours in, I started having some visual hallucinations. I thought I saw someone standing in my bedroom, and it looked like a child. I kept seeing flexeril maximum daily dose bright flashes of light that were gone before I could even register that I had seen them. At that point, I needed it, and I slept for seven hours straight. I was still in a daze, and I didn’t take any more of the drug.

Flexeril works by acting on the central nervous system, blocking pain sensations that would otherwise travel from sore and spasming muscles to the brain. This pain-blocking mechanism can contribute to abuse of the medication and may result in Flexeril addiction. Skeletal muscle relaxants are prescription medications commonly used to treat muscle pain and muscle spasms. If you have back pain or have suffered a strain or sprain, your healthcare provider may offer you a skeletal muscle relaxant such as methocarbamol (Robaxin) or cyclobenzaprine (Fexmid, Amrix). The combination of Flexeril and alcohol can cause serious problems in the central nervous system, the consequences of which may end up being fatal.

Our Flexeril (cyclobenzaprine) Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication. Check the labels on all your medicines (such as allergy or cough-and-cold products) because they may contain ingredients that cause drowsiness. Older adults may be more sensitive to the side effects of this drug, especially drowsiness, confusion, constipation, or trouble urinating. Drowsiness and confusion can increase the risk of falling. Before taking cyclobenzaprine, tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems.

What other drugs will affect Flexeril?

Therefore, this drug should only be used in pregnancy if clearly needed. Talk with your doctor about other drug options that may work for you. Many insurance companies require prior authorization for this drug. This means your doctor will need to get approval from your insurance company before your insurance company will pay for the prescription. You should not need a new prescription for this medication to be refilled. Your doctor will write the number of refills authorized on your prescription.

• Your doctor may start you on a lowered dose or a different dosing schedule.
• The goals of treatment include managing muscle pain and improving functional status so the patient can return to work or resume previous activities.
• I thought I saw someone standing in my bedroom, and it looked like a child.
• As mentioned above, there is not a significant difference between Robaxin, Fexmid, Amrix, and other muscle relaxants in terms of efficacy in treating acute low back pain, other musculoskeletal pain, and muscle spasms.
• That means that both Flexeril and alcohol have a tendency to slow down the body’s natural processes.

Cyclobenzaprine is one of the most studied skeletal muscle relaxants, with solid evidence and systematic reviews supporting its effectiveness. Given the high affinity of cyclobenzaprine for H1R, it is somewhat surprising that only 30%–40% of patients on cyclobenzaprine experience significant drowsiness and sedative-hypnotic effects. This less-than-expected proportion agrees with effects seen with other first-generation antihistamines, including diphenhydramine, and may be a result of metabolites, which in that case can cause paradoxical stimulation (de Leon and Nikoloff, 2008). In the case of cyclobenzaprine, it is known that dosage, administration, and formulation can also play a role, given the relatively slow biotransformation and accumulation of the agent. Finally, since cyclobenzaprine acts in part via inhibition of NET and also exhibits α2-adrenoreceptor antagonism (Muramatsu et al., 1993), sedative effects may be offset by norepinephrine-mediated stimulation. The physical effects of Flexeril include relaxation to the muscles.

Cyclobenzaprine Overdose: Side Effects & Dangers of Abuse Flexeril

Do not take more or less of it or take it more often than prescribed by your doctor. 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. 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. For these reasons, in the elderly, cyclobenzaprine should be used only if clearly needed.

As such, our results demonstrate that the primary adverse effect encountered by patients, namely drowsiness and somnolence, is likely mediated by functional antagonism of central H1R. There is also a slight risk that abuse of Cyclobenzaprine or Flexeril can lead to serotonin syndrome. Serotonin syndrome occurs when you take medications that cause an excess of serotonin in your system. Since cyclobenzaprine is commonly prescribed for short term use to aid patients with muscle spasms or musculoskeletal conditions, those who are already using medication to manage separate conditions are at a higher risk of this condition.

Although the absolute mechanism of action of cyclobenzaprine remains elusive, it is known to act centrally within the brainstem to decrease efferent α and γ spinal motor neurons that regulate muscle reflex and activity (Barnes, 1976; Barnes and Adams, 1978). Drug interactions and side effects are always possible when taking a muscle relaxer or any other prescription drug. For that reason, you should consider a few risk factors before taking cyclobenzaprine, whether it’s for muscle pain and discomfort or to facilitate better sleep habits in the short term. 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.

They belong to two different drug classes – muscle relaxant and benzodiazepine, respectively. The only salient difference is that Valium has a higher potential to cause drug dependency than Flexeril. However, your physician can better decide which drug is better for your back pain. 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.

This is because cyclobenzaprine has a chemical structure like a tricyclic antidepressant. The 5-panel test is the general test used by employers and doctors. It includes meth, opiate, THC, Benzodiazepine, and cocaine. It has a half-life of 18 hours so it will stay in the body for about 90 hours. This means it will show up on drug tests for nearly 4 days.
