Based on the available information, there is no explicit warning or interaction identified between avocado intake and Lipitor (atorvastatin) dosage. Lipitor is a statin medication used to treat high cholesterol levels, and avocados are a nutritious fruit known for their healthy fats [3].

According to the National Center for Biotechnology Information (NCBI) article, avocados contain monounsaturated fatty acids, fiber, and other bioactive components that may contribute to cardiovascular health [1]. However, the article does not discuss any specific interactions between avocados and cholesterol-lowering medications like Lipitor.

The drug patent watch and RxList websites for Lipitor do not mention avocados as having any interactions with the drug [2][3]. Nonetheless, it is crucial to consult a healthcare professional or pharmacist for personalized advice, as individual responses to medications and food interactions can vary [1].

In summary, there is no clear evidence or warning regarding avocado intake affecting Lipitor dosage based on the provided sources. However, it is always best to consult a healthcare professional for personalized advice.
