The typical half-life of Lipitor, the brand name for the drug atorvastatin, is approximately 14 hours [1]. This information is based on the drug's official prescribing information provided by the Food and Drug Administration (FDA) [1]. The half-life of a drug refers to the amount of time it takes for the concentration of the drug in the body to decrease by half.

It is important to note that the half-life of a drug can be affected by various factors, such as age, liver and kidney function, and interactions with other medications [2]. Therefore, individual results may vary.
