Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the body [2]. It belongs to a class of drugs called statins, which work by inhibiting an enzyme involved in the production of cholesterol in the liver [2]. Blood thinners, on the other hand, are medications that prevent the formation of blood clots, which can lead to serious health complications such as stroke and heart attack [3].

According to the sources provided, Lipitor is not a blood thinner [3]. It does not affect the ability of the blood to clot, nor does it interact with blood thinners in any significant way [3]. Therefore, it is generally safe to take Lipitor with blood thinners, although it is always important to consult with a healthcare provider before taking any new medications, including over-the-counter drugs and supplements [2].

In conclusion, Lipitor is not a blood thinner and can be taken with blood thinners if necessary. However, it is important to consult with a healthcare provider before taking any new medications to ensure safety and avoid potential drug interactions.
