Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the blood. The dosage of Lipitor varies depending on the individual and their specific needs. However, it is important to note that any changes in dosage should be made under the guidance of a healthcare professional.

According to Drug Patent Watch [1], the patent for Lipitor expired in 2011, which means that generic versions of the drug are now available. This may result in a change in the cost of the medication for some individuals, as generic versions tend to be less expensive than brand-name drugs.

While Lipitor is generally considered safe and effective, it is not without potential side effects. The Mayo Clinic [2] notes that some of the common side effects of statins, including Lipitor, may include muscle pain, liver damage, and digestive problems. However, these side effects are rare and typically mild.

It is important to note that the benefits of taking Lipitor, or any statin medication, typically outweigh the risks for individuals with high cholesterol. According to the British Heart Foundation [3], statins have been shown to significantly reduce the risk of heart attacks and strokes in individuals with high cholesterol.

In conclusion, any changes in Lipitor dosage should be made under the guidance of a healthcare professional. While the medication may have potential side effects, it is generally considered safe and effective for lowering cholesterol levels. It is also important to note that the availability of generic versions of the drug may result in a change in cost for some individuals. Overall, the benefits of taking Lipitor typically outweigh the risks for individuals with high cholesterol.
