Lipitor is a medication used to lower cholesterol levels in the body [1]. According to the sources provided, there is no evidence to suggest that Lipitor interacts negatively with salt substitutes specifically. However, it is important to note that Lipitor can interact with certain minerals, such as magnesium and calcium, which are often found in salt substitutes [2][3].

According to the US Pharmacist article, taking Lipitor with magnesium-containing antacids may decrease the effectiveness of the medication [2]. Additionally, the Heart Association warns that calcium supplements may interfere with the absorption of Lipitor [3]. Therefore, it is recommended to avoid taking Lipitor with supplements that contain magnesium or calcium.

It is always important to consult with a healthcare provider or pharmacist before taking any new medication or supplement, as they can provide personalized advice based on individual health conditions and medications.
