Lipitor is a medication used to lower cholesterol levels in the blood. According to Drug Patent Watch [1], the active ingredient in Lipitor is atorvastatin calcium. It is important to note that some foods, including guacamole, can interact with Lipitor, affecting its effectiveness and causing potential side effects.

Stat News [2] suggests that consuming grapefruit or grapefruit juice while taking Lipitor can increase the drug's concentration in the blood, leading to an increased risk of side effects. However, there is no direct evidence that guacamole has a similar effect.

Prevention [3] recommends consuming a diet low in saturated and trans fats while taking Lipitor. Guacamole is a good source of healthy fats, but it should be consumed in moderation, along with other sources of healthy fats such as nuts and olive oil.

In conclusion, there is no specific information available regarding the safe amount of guacamole to consume while taking Lipitor. However, it is important to maintain a balanced diet and avoid consuming large amounts of grapefruit or grapefruit juice while taking this medication. It is recommended to consult with a healthcare provider or a registered dietitian for personalized advice on diet and medication interactions.
