According to the sources provided, there is a potential interaction between Lipitor (atorvastatin) and potassium chloride. Lipitor is a medication used to lower cholesterol levels in the blood, while potassium chloride is a supplement used to treat low potassium levels in the body.

The drug interaction checker on drugs.com [2] suggests that taking Lipitor with potassium chloride may increase the risk of developing high potassium levels in the blood, a condition known as hyperkalemia. This can lead to serious health problems, such as irregular heartbeat and muscle weakness. Therefore, it is important to monitor potassium levels while taking Lipitor and potassium chloride together.

GoodRx [3] also lists Lipitor as a medication that can potentially interfere with potassium levels in the body. It is recommended to discuss any concerns about potassium levels with a healthcare provider before taking Lipitor or any other medication.

DrugPatentWatch [1] provides information about the patent status of Lipitor but does not offer any information about its potential interactions with potassium chloride.

In conclusion, based on the sources provided, there is a potential interaction between Lipitor and potassium chloride that can lead to high potassium levels in the blood. It is recommended to monitor potassium levels and discuss any concerns with a healthcare provider before taking these medications together.
