Flexeril will stay for up to 10 days after the last intake of the drug. It starts being detectable in 3-4 hours after the oral ingestion. However, the other ways of intake (sniffing or smoking) can affect the speed of metabolizing the substance.

In any way, the hair test rarely applies for cyclobenzaprine testing.
How Long Flexeril Stays in Saliva
Being part of the body system, Flexeril can stay in saliva for 3 to 10 days depending on the rate of body excretion. A prominent variable that affects the duration of Flexeril in the system is a hepatic/renal function of an individual. Patients with the hepatic disorder tend to experience a reduction of CYP450 isoenzyme function, hence, a prolongation of metabolites excretion, thereby causing an increased duration of cyclobenzaprine in the body.
Does Flexeril Show Up on a 12-Panel Drug Test?
Flexeril won’t be detected on a 12-panel drug test. Flexeril isn’t visible on regular blood, saliva, or urine test. Instead, it can be detected as an antidepressant drug in the body, and only shows up if a specific test is carried out for that. In cases like this, the patient is subjected to a special toxicology test, and only then, would cyclobenzaprine show up as an antidepressant.
Variables That Affect How Long Flexeril Stays in System
How long does Flexeril stay in system? Variables such as age/sex, body mass, metabolic rate, genetic, dosage, the frequency of drug administration among others affect how long cyclobenzaprine stays in the system. Listed below are other factors that affect how long Flexeril stays in the body.
Oftentimes, two people may take a drug, but one will retain it longer in the body than the other. The question is why this experience? It is simply because of some individual peculiarities regarding age/sex, body mass, metabolic rate and so on. Cyclobenzaprine mechanism of action is to increase brainstem-mediated noradrenergic inhibition of spinal cord neurons.
The frequency/duration of drug administration
This is another variable aside individual differences that can lead to how long does Flexeril stay in the system. It can be expected to stay longer in the system of anyone who takes it at a higher frequency. For instance, this can either be taken 3 times/ day or once/day. It will stay longer in the body of the person that takes it 3 times daily than the one that takes it for just once daily. There are some important side effects of cyclobenzaprine to look out for before taking this drug.
The generally prescribed dosage is Flexeril 5mg, but sometimes doctors prescribe a higher dosage of 10mg for higher complications. The higher the dosage, the longer it takes generic Flexeril to be eliminated from the system after completion.
Other combined drugs
Either ignorant or according to doctor’s prescription, some drugs can be combined with cyclobenzaprine depending on the state of health of the individual involved. However, the combined drug tends to reduce the speed of this drug excretion. Some of these combined drugs that can hinder easy removal are chloramphenicol, Ritonavir, etc. Flexeril and Ibuprofen. are another drug interactions to know about.
How to Remove Flexeril From System Faster?
There are different methods of removing Flexeril from the body. They include:
- CYP450 inducers drugs
- Activated Charcoal
- Medical Detox
Cyclobenzaprine drug test can be carried out to determine the degree of concentration in the blood. At rehab centers, people are helped through proper monitoring to get the Cyclobenzaprine off their system faster. Variables like individual differences, frequency/duration of the drug, and other combined drugs are known to affect how long cyclobenzaprine stays in the system. Medical detox can also be prescribed as the fastest on how to flush Flexeril out of the system.
