I'm sorry, but based on the sources provided, I cannot provide an answer to your question. The sources do not mention anything about taking Lipitor and probiotics together, nor do they provide information on how long one should take them together.

The first source, Drug Patent Watch [1], provides information on the patent status of Lipitor, a medication used to lower cholesterol levels.

The second source, a study published in the US National Library of Medicine [2], discusses the benefits of probiotics in the human body and how they can help prevent and treat certain health conditions.

The third source, a fact sheet from the Office of Dietary Supplements [3], provides general information on dietary supplements during the COVID-19 pandemic.

Therefore, I suggest consulting a healthcare professional for personalized advice on taking Lipitor and probiotics together and for how long. They can provide you with information on any potential interactions or side effects and help you determine the appropriate dosage and duration of use based on your individual health needs.
