If you are taking Lipitor, also known as atorvastatin, you should not stop taking it abruptly without consulting your doctor [2][3]. Lipitor is a type of statin, a medication that is used to lower cholesterol levels in the blood [1]. Stopping statins abruptly can cause a rapid increase in cholesterol levels, which can increase the risk of heart attacks and strokes [2][3].

It is important to note that if you experience any side effects from Lipitor, you should talk to your doctor before discontinuing the medication [3]. In some cases, your doctor may recommend that you switch to a different type of statin or adjust your dosage to minimize side effects [3].

In general, it is not recommended to stop taking statins unless there is a compelling reason to do so [2]. If you are considering stopping Lipitor, you should talk to your doctor first to discuss the risks and benefits of continuing the medication [2][3].
