Lipitor (atorvastatin) is a medication used to lower cholesterol levels in the blood. Like any other medication, it can interact with other drugs, causing side effects.

According to GoodRx [2], Lipitor can interact with over 300 drugs, including antifungal medications, antibiotics, and heart medications. Some of these interactions can increase the risk of muscle damage, kidney problems, and liver problems. Patients should inform their healthcare provider of all the medications they are taking before starting Lipitor.

WebMD [3] states that Lipitor can cause side effects such as muscle pain, weakness, and tenderness. These symptoms can be a sign of a rare but serious side effect called rhabdomyolysis, which can cause kidney damage. Patients should contact their healthcare provider immediately if they experience any of these symptoms.

DrugPatentWatch [1] notes that Lipitor can also cause digestive problems, such as constipation, diarrhea, and nausea. Some patients may experience headaches, insomnia, or skin rash.
