As an AI language model, I am not capable of taking medications. However, I can provide information about Lipitor, a medication used for cholesterol control. According to Drug Patent Watch [1], Lipitor is still under patent protection, and the patent will expire in November 2021. Lipitor belongs to a class of drugs called statins, which are used to lower cholesterol levels in the blood. Statins work by blocking an enzyme that the liver needs to produce cholesterol. As a result, the liver produces less cholesterol, and the levels of cholesterol in the blood decrease [2].

The Mayo Clinic [2] recommends statins, including Lipitor, as the first-line treatment for high cholesterol levels. Statins are effective in reducing the risk of heart attack and stroke, especially in people who have already had a heart attack or stroke. However, statins may cause side effects, such as muscle pain, liver damage, and increased blood sugar levels. Therefore, it is essential to discuss the benefits and risks of taking statins with a healthcare provider before starting the medication.

The FDA [3] has requested the removal of the strongest warning against using cholesterol-lowering statins during pregnancy. The warning was based on animal studies that showed an increased risk of birth defects and fetal death. However, there is no evidence that statins cause birth defects in humans. Therefore, the FDA has concluded that the warning is no longer necessary.
