Lipitor is a medication used to lower cholesterol levels in the blood. It is important to follow the instructions of a healthcare provider when taking Lipitor, including any recommended splitting schedule.

According to the sources provided, Lipitor is available in tablet form in various strengths, including 10mg, 20mg, 40mg, and 80mg. The tablets are not scored, which means they are not intended to be split. However, some healthcare providers may recommend splitting tablets as a way to adjust the dosage and save money on medication costs.

It is important to note that not all medications are suitable for splitting, and it should only be done under the guidance of a healthcare provider. In the case of Lipitor, a study published in the Journal of General Internal Medicine found that splitting tablets did not significantly affect the medication's efficacy or safety [2]. However, this does not mean that splitting Lipitor tablets is safe for everyone, and it is still important to consult with a healthcare provider before doing so.

If a healthcare provider does recommend splitting Lipitor tablets, they may suggest a specific schedule. GoodRx suggests using a pill splitter to ensure that the tablets are split evenly and recommends splitting tablets as close to the time of use as possible to minimize exposure to air and moisture [3].

In conclusion, while Lipitor tablets are not intended to be split, some healthcare providers may recommend doing so. It is important to consult with a healthcare provider before splitting Lipitor tablets, and to follow any recommended schedule closely.
