Lipitor is a brand name for atorvastatin, which is a type of medication used to lower cholesterol levels in the blood. According to the Mayo Clinic [2], there are no specific types of nuts that need to be avoided when taking Lipitor. In fact, nuts are generally considered to be a heart-healthy food and can help to lower cholesterol levels. However, it is important to note that some nuts are high in calories and fat, so they should be consumed in moderation as part of a healthy diet.

The Guthrie Clinic [3] advises patients taking blood thinners or statins, including Lipitor, to avoid consuming large amounts of vitamin K-rich foods, such as leafy greens, broccoli, and Brussels sprouts, as these can interfere with the medication's effectiveness. However, nuts are not mentioned as a food to avoid in this context.

DrugPatentWatch [1] provides information about the patent status of Lipitor but does not provide any information about specific types of nuts to avoid while taking the medication.

In summary, there are no specific types of nuts to avoid when taking Lipitor, according to the Mayo Clinic [2]. However, it is important to consume nuts in moderation as part of a healthy diet. Patients taking blood thinners or statins, including Lipitor, should avoid consuming large amounts of vitamin K-rich foods, but nuts are not mentioned as a food to avoid in this context, according to the Guthrie Clinic [3].
