Does Cyclobenzaprine Show Up on a Drug Test

Cyclobenzaprine is a muscle relaxant often given for back pain, sprains, or muscle spasms. Many people ask: does cyclobenzaprine show up on a drug test? The answer depends on the type of test, the dose, and the person’s body.

At Lynk Diagnostics, a trusted drug testing center dedicated to rehab facilities, we provide accurate information about how drugs are detected in the body. This article will explain how cyclobenzaprine is tested, how long it stays in the system, and what factors—like metabolism, liver function, and genetics—can affect detection.

Cyclobenzaprine is a prescription skeletal muscle relaxant. Doctors often use it for short-term therapy after an injury, sprain, or back pain. It works on the central nervous system to reduce spasm and pain.

Cyclobenzaprine is not an opioid, benzodiazepine, or controlled substance, but it does act as a depressant on the nervous system. The Food and Drug Administration (FDA) approved it as an antispasmodic medicine.

• Medical monitoring by a health care provider
• Sports programs concerned with addiction or misuse

At Lynk Diagnostics, we use drug test cups and advanced lab testing to provide accurate data for rehab programs.

Most standard urine tests and workplace panels do not screen for cyclobenzaprine. Instead, they focus on:

Yes. Cyclobenzaprine is chemically close to a tricyclic antidepressant. Because of this, some tests may confuse it with an antidepressant or give a false positive.

When this happens, advanced testing such as gas chromatography-mass spectrometry (GC-MS) or liquid chromatography-tandem mass spectrometry (LC-MS/MS) is used to check the result. Lynk Diagnostics uses these confirmatory methods to ensure accurate answers.

These drugs may appear on some tests, depending on lab requests and medical need.
