Do Muscle Relaxers Show Up On Drug Test

Opioids are classified as a type of depressant that can affect the brain’s ability to feel pain. There are many different opiates, but a 10-panel drug test will only detect the three most common: heroin, morphine, and codeine.

Although your employees can receive morphine for pain control, positive tests for these basic opioids should be taken seriously. Heroin is the most dangerous and addictive of the three and can cause extreme withdrawal symptoms just 6 to 12 hours after your last use.

Is there any danger in taking Flexeril?

There are quite a few people who have become psychologically dependent on cyclobenzaprine, but the federal government will not classify it as addictive.

As mentioned, cyclobenzaprine can also cause mild to moderately severe withdrawal symptoms, which is often another benchmark of an addictive substance.

How long does Flexeril last in laboratory tests?

The time Flexeril appears during a projection depends on:

  • The type of drug test: Flexeril appears in laboratory tests for different durations. Hair tests can find Flexeril longer, while blood tests only work for a short time.
  • Your Flexeril usage habits: Using Flexeril in large amounts or too often can cause it to stay in your system longer. If you use Flexeril short-term (or as directed by your doctor), you’re less likely to take it for a long time. The frequency of use is important, as is the dose.
  • Your Health: Healthy people tend to absorb medications faster. Specifically, the health of your kidneys and liver is important. Kidney and liver damage make it difficult for drugs to leave the bloodstream.
  • Your metabolism: The faster your metabolism, the more likely you are to process Flexeril quickly. It depends on factors such as age, weight, height, and genetics. Your lifestyle matters too, like your eating habits and your exercise habits.

Side effects of taking cyclobenzaprine

Taking cyclobenzaprine may cause the following side effects.

  • Blurred vision that prevents seeing fine details
  • Dizziness, drowsiness or lightheadedness
  • Dry mouth or xerostomia


  • Blood test: 24 hours
  • Urinalysis: 2-3 days
  • Saliva test: up to 4 hours

Some people use muscle relaxants to achieve pleasurable sensations. There are a number of health and legal reasons not to, and it should be noted that not all muscle relaxants can produce pleasant effects. Over time, the body can become chemically dependent on muscle relaxants, which may require you to undergo a detoxification process guided by medical professionals.
