Clinical Significance

Isopropyl alcohol has twice the CNS depressant action as ethanol. Severe intoxication can lead to coma or death. There is no endogenous isopropyl alcohol present in the body. Isopropyl alcohol metabolizes to acetone. If isopropyl swab is used to disinfect skin before drawing a specimen, isopropyl alcohol may be detected without any acetone.
