Lipitor is a medication used to lower cholesterol levels in the blood. According to the sources provided, there is no official recommendation on how often Lipitor should be split. However, it is possible to split Lipitor tablets safely, as long as certain precautions are taken [2].

The first source provides information about the patent expiration of Lipitor, but it does not offer any guidance on how to split the tablets [1]. The second source states that it is safe to split Lipitor tablets as long as the tablets are scored (meaning they have a line down the middle) and the person splitting the tablet uses a pill splitter rather than a knife or scissors. The article recommends that people only split the tablets once a day and take the other half at the same time the following day [2].

The third source provides general information about pill splitting and does not specifically address Lipitor. However, it notes that not all medications can be split safely and that patients should always consult with their doctor or pharmacist before splitting any medication. Additionally, the article recommends that patients only split tablets that are scored and that they use a pill splitter to ensure accuracy [3].

In summary, there is no official recommendation on how often Lipitor should be split. However, according to the sources provided, it is safe to split Lipitor tablets once a day as long as the tablets are scored and a pill splitter is used. Patients should always consult with their doctor or pharmacist before splitting any medication to ensure that it is safe and appropriate for their individual needs [2][3].
