Lipitor is a brand name for the drug atorvastatin, which is a type of statin used to lower cholesterol levels in the blood [1]. Statins work by blocking the enzyme responsible for producing cholesterol in the liver. As with any medication, stopping Lipitor can have both short-term and long-term effects on the body.

According to GoodRx, stopping statins like Lipitor abruptly can lead to an increased risk of heart attack and stroke, especially in people who have already had a cardiovascular event [2]. This is because the sudden discontinuation of statins can cause a rapid increase in cholesterol levels, which can lead to the formation of blood clots and plaque buildup in the arteries. Additionally, stopping statins can cause a rebound effect, where the body produces more cholesterol than it did before starting the medication.

A study published in the Journal of the American College of Cardiology found that people who stopped taking statins had a higher risk of dying from cardiovascular disease than those who continued taking the medication [3]. The study also found that people who stopped taking statins were more likely to be hospitalized for heart attacks and strokes.

Other potential long-term effects of stopping Lipitor include an increased risk of developing type 2 diabetes, as well as an increased risk of cognitive decline and dementia [2]. However, more research is needed to fully understand the relationship between statins and these conditions.

In summary, stopping Lipitor can have both short-term and long-term effects on the body. Abruptly discontinuing the medication can increase the risk of heart attack and stroke, and may also lead to a rebound effect where cholesterol levels increase rapidly. Long-term effects may include an increased risk of cardiovascular disease, type 2 diabetes, and cognitive decline. It is important to speak with a healthcare provider before stopping any medication, including Lipitor.
