Lipitor is a medication used to lower cholesterol levels in the body. According to Drug Patent Watch [1], Lipitor's active ingredient is atorvastatin calcium, which is an HMG-CoA reductase inhibitor. Salt substitutes, on the other hand, are products that contain potassium chloride instead of sodium chloride. These substitutes are commonly used by people with high blood pressure or heart disease who need to reduce their sodium intake.

However, mixing Lipitor with salt substitutes can be dangerous. According to NKCH [2], potassium chloride can increase the level of potassium in the body, which can be harmful to people with kidney disease or those taking certain medications. Potassium levels can also increase if a person is taking potassium supplements, ACE inhibitors, or potassium-sparing diuretics.

Furthermore, according to US Pharmacist [3], high levels of potassium in the body can lead to heart rhythm problems, muscle weakness, and even paralysis. These effects can be severe and can lead to hospitalization or even death.

In conclusion, mixing Lipitor with salt substitutes can be dangerous, especially for people with kidney disease or those taking certain medications. It is important to talk to a healthcare provider before taking any new medication or supplement to avoid potential interactions.
