According to Guthrie Health, it is recommended that individuals taking blood thinners or statins, such as Lipitor, avoid consuming large amounts of foods high in vitamin K, such as avocado. Vitamin K is known to interfere with the effectiveness of blood thinners. However, the amount of vitamin K in avocado is relatively low, and it is unlikely to cause any significant interactions with Lipitor.

It is important to note that certain medications, including Lipitor, can interact with grapefruit and grapefruit juice. Grapefruit can increase the levels of Lipitor in the blood, which can increase the risk of side effects. However, there is no evidence to suggest that avocado has a similar effect on Lipitor.

In general, it is important to speak with a healthcare provider before making any significant changes to your diet or medication regimen. They can provide personalized recommendations based on your individual health needs and medication regimen.
