Is Cyclobenzaprine A Narcotic? Flexeril Drug Classification

Last Updated: June 3, 2020

Authored by Sharon Levy, MD, MPH

As Cyclobenzaprine is a drug which is regularly prescribed as a muscle relaxant, it is important to be aware of its classification. This type of drug is more specifically known as a tricyclic antidepressant and is used in the treatment of the pain associated with injuries of the muscle. Learn more about the Flexeril drug class.

Is Cyclobenzaprine a Narcotic?

The Cyclobenzaprine narcotic question is a great place to start when looking into the drug classifications of Flexeril. Due to the fact that it has not been classified as an addictive drug and because it is in a separate class of drugs, it is not considered to be a narcotic. The reason that there is even a Flexeril narcotic debate at all is that other similar muscle relaxing drugs have been classed as controlled substances.

Is Flexeril a Controlled Substance?

There are some other muscle relaxers that have been classified by the Department of Justice as a controlled substance. The answer to the question “Is Cyclobenzaprine a controlled substance?” however remains a firm “No.” Although there have been tests that show that the drug can cause withdrawal symptoms, any Flexeril controlled substance questions have been answered quite clearly in the Cyclobenzaprine classification. Because the term ‘narcotic’ only refers to drugs that have been classified as controlled substances, it cannot be classed as a narcotic.

Is Cyclobenzaprine a Benzo?

The question “Is Flexeril a benzo?” is asked much more common than people think. Both CNS depressants and benzos (or Benzodiazepines as they are known) are used to treat similar types of muscle related pain. Benzodiazepines are however not part of the Cyclobenzaprine drug class and is a member of a drug class known as Central Nervous System Depressants. If being treated with the Cyclobenzaprine muscle relaxant patients are advised not to use Benzodiazepines as the side effects of both drugs are similar, and use of the two together could greatly enhance these effects.

Is Cyclobenzaprine an Opiate?

The Flexeril classification makeswoman holding yellow pills in hands it easy to answer the question “Is Flexeril an opiate?”. Put simply the answer is that while Cyclobenzaprine is regularly used during treatment of opiate withdrawal, it is not itself an opiate. Although Cyclobenzaprine 10 mg can get a person high, It cannot be considered to be an opiate because it is not made using opium poppy. The reason that many might think that it is an opiate is due to the fact that it is used to treat opiate withdrawal. However, it is not used to replace the opiate that the patient is addicted to but rather to ease the muscle pain and anxiety that they suffer during the withdrawal process.

Is Flexeril an Opioid?

Opioid medication is used to treat many of the same symptoms and disorders as CNS depressants, so it is only natural that some people confuse the two drug types. However, Flexeril is not an opioid. So when it comes to using Cyclobenzaprine in combination with opioid-based drugs, it is not advised. The use of combinations such as Flexeril and Tramadol can be fairly dangerous due to both drug types having a similar effect on the body. The use of Muscle relaxers with any opioid can cause a higher probability of addiction.

Is Flexeril a NSAID?

When a patient that is suffering from the symptoms of acute muscular pain is in need of treatment, there are a number of routes that they can take. They could be prescribed Cyclobenzaprine 5mg, or they could be offered a NSAID-based treatment. Because two of these routes are muscle relaxers and NSAID or Non-steroidal anti-inflammatory drugs it is easy to believe that the two are indeed the same thing. NSAID drugs are however not in the Cyclobenzaprine class. Put simply, Flexeril is a muscle relaxer and not an NSAID.

Is Cyclobenzaprine a Muscle Relaxer?

Considering that the primary use of Flexeril when it comes to treatment is as a muscle relaxer, the answer to the question “Is Cyclobenzaprine a muscle relaxer?” should be quite clear. Yes, it is. Cyclobenzaprine HCL (hydrochloride) is considered amongst the best type of drug to use when treating the muscle pains and spasms that are associated with various musculoskeletal conditions.

Cyclobenzaprine Schedule and Classification

The classification of Flexeril states that it is considered to be a type of Central Nervous System or CNS muscle relaxer. This prescription-only drug is used in most cases to treat acute muscle pain, but it has also shown high levels of success when used to treat the various symptoms connected to addiction withdrawal. There is currently no Flexeril Schedule held by the Department of Justice as it is still considered by them to be a ‘non-scheduled’ muscle relaxant.
These are the clear classifications of Cyclobenzaprine showing that while it is a CNS muscle relaxer, it is neither an opioid or a benzo. It is also non-scheduled and therefore it is not a controlled substance. However, it does not mean that Flexeril is not addictive and the abuse of this substance does not require treatment. There are both inpatient and outpatient rehabs available for those willing to overcome the drug dependence.

    I am taking cyclobenzaprine 10 mg at night to relax terrible muscle spasms in my back, I’m on my second week and have found how much better my back feels, I’m scared to go off them is it safe to keep taking them for a while?
    • Kate
      As long as your doctor continues to prescribe them, and they continue to help, keep taking them. If they start giving you problems or side effects, then it’s time to talk to your doctor again.
  • Leslie
    My daughter has been taking them for 2 years. They were prescribed to her by her dentist due her extreme teeth clenching at night. She went off due to a heart condition and is suffering from withdrawal. Mostly she can’t not sleep because her muscle won’t relax. Be careful with it is all I can recommend, she’s miserable.and tired.
    • Allyn
      thank you for sharing your daughter’s experience. My Dr. prescribed it for a muscle spasm in my back…I wonder if it wouldn’t be better to have it massaged .
      • Mary pennington
        Can I safely take cyclobenzoprine if I have an irregular heart beat.
  • Losa
    I took cyclobenzaprine 10mg to help with muscle spasm on my left side and I have a drug screening (test panel 6) in 1 day, will this affect my drug screening?
    • Rhia
      Hey. I have muscle spasms on my left foot too, with my toes moving involuntarily. Did you have any specific kind of disease or anything regarding of your left foot spasm?
      • Allyn
        no, but I’m taking it for a muscle spasm in my back.
      • Amber Holly
        I’ve had RLS for years with nothing proving relief.
        • Linda Hamrick Moss
          I take Reguip.. Works great for. Me…. 2 mg. In morning and 2 mg. In the evening. Can’t live without it.
  • George Torres
    I am a addictions counselor and I need an answer to the question… Can cyclobenzapine create a false positive for benzodiazapines?
    • Aaron
      No, it cannot create a false positive for benzo’s. I do have some experience as I am a Medication Technician but, I also take Cyclobenazaprine 10 mg 3X/day. I’ve been taking it for several years now. I have had several drug tests done during this time. Twice for my Doctor and once for a job and have never failed for benzo’s. I would think someone may be trying to pull one on you. However, when it comes to urine dip tests, one can have a false positive for anything on the stick as they are not 100% accurate. Retest or send to an actual lab for accuracy. I have degenerative disc disease, bulging discs which pinch my nerve & cause major pain & numbness. I am anti-narcotic and will not take anything that can be addictive. Just a personal choice of mine. This medication was a lifesaver for me. It actually helps the pain. I would recommend to others who have lower back pain.

    I only have one kidney.Is it safe to take Flexeril?
  • JZ
    Cyclobenzaprine is NOT a tricyclic antidepressant. It is a skeletal muscle relaxant. Tricyclic antidepressants include medications such as amitriptyline and nortriptyline.
  • Rhia
    I have a muscle spasm on my left foot. My toes are moving involuntary and aches on the arch of my foot under.
  • Malvina Ann Schmitt
    At first I hated Cyclobenzaprine , I have a severe rotator cuff problem and it’s debil itaing and painful and I can’t sleep at night or day sometimes. I’ve had 3 strokes also and was not taking flexeril during that period. It hurt my right side. I’ve started taking them off & on when I’m desperate for sleep. They really help me sleep at night. It can make have a dry mouth on occasion but this side effect is so non significant compared to not having a good nights sleep!!
  • Lillian
    I just started taking cyclobenzaprine 10mg how long does it takes to start working.
  • Shandy Shea
    Flexeril is only effective for muscle spasms and muscle pain if you are stretching. The purpose of a muscle relaxer is to relax the muscle enough without pain in order to stretch it so it doesn’t revert back to that kinked up state that created the discomfort. It’s useless if you aren’t stretching!!!
  • Laurie
    I have found Cyclobenzaprine to be a tremendous relief. Since I prefer to take as little as possible, I discussed with my doctor and pharmacist if I could divide the tablet safely. I have found that one-fourth to half a 10 mg tablet (2.5 mg up to 5 mg) is sufficient to do the job. I find that less is often more when it comes to many drugs and side effects can be minimized. I’m thankful to have this option for pain relief combined with a neurostimulator by NEVRO. After having been disabled for over ten years, I’m even able to cook and make bread a couple of times a week. Yay for modern medicine.
