After reviewing the available information, I can estimate that Lipitor, a medication used to treat high cholesterol, typically reaches its full effectiveness within 2-4 weeks [1]. However, it is important to note that individual results may vary, and it is always best to consult with a healthcare professional for personalized advice.

Lipitor, also known as atorvastatin, is a type of drug called a statin, which works by reducing the amount of cholesterol produced by the liver [2]. This helps to lower the levels of "bad" cholesterol (low-density lipoprotein, or LDL) and triglycerides in the blood, while increasing the levels of "good" cholesterol (high-density lipoprotein, or HDL) [2].

According to DrugPatentWatch.com, Lipitor was first approved by the FDA in 1996 and its patent expired in 2011 [3]. Since then, generic versions of the drug have become available, which can help to make the medication more affordable for patients.

In summary, while the full effectiveness of Lipitor can vary from person to person, it typically takes 2-4 weeks for the medication to reach its full potential. It is important to consult with a healthcare professional for personalized advice and to monitor cholesterol levels regularly.
