Warnings:
Warnings serious (including fatal) hepatocellular toxicity has been reported rarely in patients receiving chlorzoxazone. the mechanism is unknown but appears to be idiosyncratic and unpredictable. factors predisposing patients to this rare event are not known. patients should be instructed to report early signs and/or symptoms of hepatotoxicity such as fever, rash, anorexia, nausea, vomiting, fatigue, right upper quadrant pain, dark urine, or jaundice. chlorzoxazone should be discontinued immediately and a physician consulted if any of these signs or symptoms develop. chlorzoxazone use should also be discontinued if a patient develops abnormal liver enzymes (e.g., ast, alt, alkaline phosphatase and bilirubin). the concomitant use of alcohol or other central nervous system depressants may have an additive effect. usage in pregnancy: the safe use of chlorzoxazone has not been established with respect to the possible adverse effects upon fetal development. therefore, it should be used in

Overdosage:
Overdosage symptoms: initially, gastrointestinal disturbances such as nausea, vomiting, or diarrhea together with drowsiness, dizziness, lightheadedness or headache may occur. early in the course there may be malaise or sluggishness followed by marked loss of muscle tone, making voluntary movement impossible. the deep tendon reflexes may be decreased or absent. the sensorium remains intact, and there is no peripheral loss of sensation. respiratory depression may occur with rapid, irregular respiration and intercostals and substernal retraction. the blood pressure is lowered, but shock has not been observed. treatment: gastric lavage or induction of emesis should be carried out, followed by administration of activated charcoal. thereafter, treatment is entirely supportive. if respirations are depressed, oxygen and artificial respiration should be employed and a patent airway assured by use of an oropharyngeal airway or endotracheal tube. hypotension may be counteracted by use of dextran, plasma, concentrated albumin or a vasopressor agent such as norepinephrine. cholinergic drugs or analeptic drugs are of no value and should not be used.

Clinical Pharmacology:
Clinical pharmacology chlorzoxazone is a centrally-acting agent for painful musculoskeletal conditions. data available from animal experiments as well as human study indicate that chlorzoxazone acts primarily at the level of the spinal cord and subcortical areas of the brain where it inhibits multisynaptic reflex arcs involved in producing and maintaining skeletal muscle spasm of varied etiology. the clinical result is a reduction of the skeletal muscle spasm with relief of pain and increased mobility of the involved muscles. blood levels of chlorzoxazone can be detected in people during the first 30 minutes and peak levels may be reached, in the majority of the subjects, in about 1 to 2 hours after oral administration of chlorzoxazone. chlorzoxazone is rapidly metabolized and is excreted in the urine, primarily in a conjugated form as the glucuronide. less than one percent of a dose of chlorzoxazone is excreted unchanged in the urine in 24 hours.
