As one of the most widely prescribed cholesterol-lowering medications, Lipitor (atorvastatin) has been a staple in the treatment of high cholesterol and heart disease for over two decades. However, like all medications, Lipitor can interact with other medications, which may lead to adverse effects or reduce its effectiveness.

Drug interactions can have serious consequences, including:

* Reduced effectiveness of medications
* Increased risk of adverse effects
* Increased risk of toxicity
* Changes in medication dosages or frequencies
