Lipitor is a brand name for atorvastatin, a medication that is used to reduce high levels of cholesterol and triglycerides in the blood. As with any medication, there are potential side effects that patients should be aware of before taking Lipitor.

According to the NHS [2], some of the most common side effects of atorvastatin include headaches, nausea, diarrhea, and muscle and joint pain. These side effects are usually mild and go away on their own after a few days or weeks of taking the medication. However, if they persist or become more severe, patients should contact their doctor.

More serious side effects of atorvastatin can occur, although they are rare. These can include muscle weakness, liver problems, and an increased risk of developing type 2 diabetes [2]. Patients who experience any of these symptoms should contact their doctor immediately.

The Mayo Clinic [3] also notes that atorvastatin can interact with other medications, such as blood thinners, antibiotics, and antifungal medications. Patients should inform their doctor of all medications they are taking before starting Lipitor.

In addition, the Drug Patent Watch [1] lists a number of potential side effects of atorvastatin, including memory loss, confusion, and depression. However, it is important to note that these side effects are rare and may not occur in all patients.

In conclusion, while Lipitor (atorvastatin) is generally considered safe and effective for reducing cholesterol levels, patients should be aware of the potential side effects of the medication. Patients should also inform their doctor of all medications they are taking before starting Lipitor. If patients experience any side effects while taking Lipitor, they should contact their doctor immediately.
