How it works

From the US prescribing label for the same active substance (Cyclobenzaprine Hydrochloride). It describes the substance, not this exact product.

Cyclobenzaprine HCl relieves skeletal muscle spasm of local origin without interfering with muscle function.

It is ineffective in muscle spasm due to central nervous system disease.

Half-life18 h

How the body breaks it down

Cyclobenzaprine is extensively metabolized, and is excreted primarily as glucuronides via the kidney.
