Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the blood. According to drugpatentwatch.com [1], Lipitor's half-life is approximately 14 hours, meaning that half of the drug will be eliminated from the body in that time. However, it can take up to 5 half-lives for a drug to be completely eliminated from the body. Therefore, it can take up to 70 hours or approximately 3 days for Lipitor to be eliminated from the body after stopping the medication [2].

While Lipitor is generally well-tolerated, it can cause some side effects. The most common side effects include muscle pain and weakness, headache, and nausea [3]. It is important to consult with a healthcare provider if any side effects are experienced.

In conclusion, Lipitor has a half-life of approximately 14 hours, and it can take up to 70 hours or approximately 3 days for the drug to be completely eliminated from the body after stopping the medication. It is important to consult with a healthcare provider if any side effects are experienced while taking Lipitor.
