It is used as a CNS and muscle depressant. Cyclobenzaprine is available as tablets as well as extended-release capsules and is taken orally. It falls under the class of drugs known as tricyclic antidepressants. The molecular structure of cyclobenzaprine is very similar to that of Amitriptyline. In fact, the two differ from each other only through a single double bond. The drug was first approved for consumption in 1977 by the FDA when it was manufactured and sold as Flexeril.
Cyclobenzaprine is generally used a part of overall recovery plan wherein the patients are recommended to take physical therapies and sufficient rest during the treatment. The drug is only used for 2 to 3 weeks at most. It works by blocking the pain impulses that are sent to the brain by the damaged muscles.

The general adult dosage is 10 mg taken three times a day. This dosage can also vary from 20 mg to 40 mg per day, divided into multiple doses. However, the daily dosage should not exceed the maximum limit of 60 mg per day. Furthermore, the drug is not recommended to be used any longer than 3 weeks. For spasms and musculoskeletal pains, the general prescription is 10 mg taken two to three times per day. Only in severe cases of pain is the dosage increased to 60 mg per day. Elderly patients and people suffering from liver issues can start with a lower dosage and increase it later if required. The medicine should always be swallowed whole with a glass of water.
If you are using an extended-release tablet, you are only required to take one tablet per day. However, if the dosage seems to be ineffective, you can have it increased after consulting the doctor. It is seen that cyclobenzaprine can be highly effective in reducing pain with peak results within the first two weeks. However, there seems to be no apparent benefit after this phase, which is also the reason why it is not recommended for long-term use. The prescriptions are also limited to a short period of time owing to the potential risk for abuse associated with the drug. First time users are also likely to experience a cyclobenzaprine 10 mg high owing to the sedative effects of the drug. However, this will eventually go away after the body has developed a tolerance to the drug.

Recreational Use of Flexeril (Cyclobenzaprine)
Although cyclobenzaprine is not as potent as many other painkillers in giving a high, it does has a propensity to give effect to an altered state.

The common street names for cyclobenzaprine are “yellow mellow” and “cyclone”. If taken in very high quantities, it can even make you feel euphoric.
Although cyclobenzaprine is not classified as a narcotic in itself, it can still be quite potent when mixed with other drugs. The most common ways of taking the drug are crushing and snorting or dissolving it in alcohol. This way, it tends to be much more intense as compared to when taken orally. Although cyclobenzaprine is used for recreational purposes, it is definitely not as mainstream as other drugs.
When used for recreational purposes, it is usually taken at dosages between 20 and 80 mg. At this dosage, it can create a feeling of relaxation and drowsiness. It can also make you feel as though you are floating. However, the more pleasurable side effects are only experienced when cyclobenzaprine is mixed with other drugs. The common substances that are taken together with cyclobenzaprine include Barbiturates, Opioid painkillers, Alcohol, and Benzodiazepines.
Can Cyclobenzaprine 10 mg Cause High?
The main purpose of cyclobenzaprine is to provide muscle relaxation. It can help in reducing pain and controlling muscle spasms after an injury. However, the relaxing effect produced by the drug may also be comparable to a high. The cyclobenzaprine 10 mg high is even more intense especially when it is taken at higher dosages or mixed with other drugs. However, it should be noted that a cyclobenzaprine 10 mg high is only experienced if the patient is new to the prescription or if it is abused by someone who is not using the drug. As the body begins to adjust itself to the drug, this high is not experienced and greater doses will be required to produce the same effects.
Cyclobenzaprine 10 mg high can be quite enjoyable. However, if the doses are being tampered on a regular basis for recreational purposes, it can also lead to some severe health problems. Dangerous fluctuations in the blood pressure, seizures, and cardiac arrest are known to occur with cyclobenzaprine. In some cases, it can also lead to a depression of the central nervous system. In any case, opting for higher doses in order to experience a high can have more negative consequences than the rewards.
How does Cyclobenzaprine 10 mg high feel like?
It is entirely natural for people who have never taken cyclobenzaprine to wonder what the high would feel like. As related by the people who have used the drug for recreational purposes, the high is not as euphoric as it tends to get with other drugs. It only induces a feeling of calmness and relaxation. Even then, the cyclobenzaprine 10 mg high is quite appealing which is why people are often tempted to continue with the abuse.
However, studies have shown that most people who actually use the drug for recreational purposes often use it with other drugs, often in an illegal manner. In some cases, people have also known it in place of sleeping pills. After taking the drug, the person feels as if he/she is floating out of her body. Some people have also experienced euphoria and hallucinations. However, the cyclobenzaprine high is definitely not as intense or good as compared to that achieved by taking other harder drugs.
The Ramification of cyclobenzaprine 10 mg high by Alcohol
Many people also use alcohol in order to enhance the cyclobenzaprine 10 mg high. However, this combination is deemed to be highly dangerous as it can have a direct consequence on the central nervous system. If it gets serious enough, the combination can even be fatal. This is because both of these substances act as central nervous system depressants. So when taken together, the natural processes in the body are slowed down by quite a significant degree. Respiration is one of the most important processes that are directly controlled by the central nervous system. So when this slows down to a dangerous degree, it can lead to alcohol poisoning, resulting in death.
Alcohol also magnifies the negative side effects that are associated with cyclobenzaprine. As a result, the person taking the two substances together can experience extreme drowsiness, dizziness, and hazy thinking. When this happens, the person is more susceptible to endure physical injuries. It can also drive the user to make bad decision resulting in self-harm. Even normal activities such as driving or walking can put the person in a high level of danger. Therefore, it is advised not to mix alcohol and cyclobenzaprine.
Due to a heightened sedation, the functioning of the brain is severely impaired. At the same time, breathing and heart rates are reduced in a dangerous manner. A number of heart failures, as well as fatalities, have been reported as a result of taking the two substances together. Cyclobenzaprine can also be equally dangerous when mixed with MAO inhibitors such as Parnate, Nardil, and Marplan. Patients who have been using these drugs should keep a gap at least two weeks before using cyclobenzaprine. Also, if the patient is having difficulties in controlling the alcohol intake and has already mixed it with cyclobenzaprine a couple of times, it is important to bring this to the doctor’s notice.

As per the U.S. Drug Enforcement Agency, cyclobenzaprine is not associated with any risk of addiction. However, many people tend to continuously abuse it, mainly owing to the cyclobenzaprine 10 mg high.
