After reviewing the sources provided, there is no information suggesting any adverse effects of Lipitor on avocado. Lipitor is a medication used to lower cholesterol levels in the body [3]. It works by blocking an enzyme that is responsible for producing cholesterol in the liver [3]. While the medication can have potential side effects, such as muscle pain and weakness, liver problems, and digestive issues, there is no evidence that it interacts with avocado in any way [3].

The sources provided give no indication that there is any link between Lipitor and avocado. The first source is a drug patent watch website that provides information about Lipitor's patent status, and the second source is a study that discusses the potential benefits of avocado on cardiovascular health [1, 2]. The third source is a drug information website that provides information on the side effects and uses of Lipitor [3].

In conclusion, there is no evidence to suggest that Lipitor has any adverse effects on avocado. However, it is always advisable to speak with a healthcare provider or a registered dietitian before making any significant changes to your diet while taking any medication [3].
