A drug overdose occurs when a toxin is unable to be successfully metabolized and removed from the body, and certain bodily functions are negatively affected. In the case of cyclobenzaprine, the Journal of Occupational Medicine and Toxicology reports that more than 100 mg of the drug taken in one dose can cause a toxic overdose.
