Based on the information provided, there is no evidence to suggest that patients taking Lipitor, a medication used to treat high cholesterol, should avoid yogurts with specific additives. Lipitor's patent information [${1}], drug details [${2}], and a resource on foods to avoid for adults with asthma [${3}] do not mention any interactions or concerns with yogurt or its additives.

However, it is essential to note that individual food intolerances or allergies may cause adverse reactions in some people. If a particular yogurt additive negatively affects a Lipitor patient, they should consult their healthcare provider for personalized advice.

It is always recommended that patients consult their healthcare providers for personalized advice on dietary concerns while taking medications.
