According to the manufacturer's guidelines and various health organizations, Lipitor (atorvastatin) should not be stored in the refrigerator. The recommended storage conditions for Lipitor are at room temperature, between 59°F to 77°F (15°C to 25°C), and away from light and moisture.

The manufacturer, Pfizer, does not recommend storing Lipitor in the refrigerator, as this could potentially affect the medication's stability and potency. In fact, the product label states that the medication should be stored at room temperature, and not in a refrigerator or freezer.

Additionally, the FDA and other reputable health organizations, such as the Mayo Clinic and the American Heart Association, also recommend storing Lipitor at room temperature, away from direct sunlight and moisture.

It's worth noting that storing Lipitor in the refrigerator could potentially cause the medication to degrade or become less effective over time. This is because refrigeration can cause the medication to absorb moisture, which can affect its stability and potency.

In conclusion, based on the manufacturer's guidelines and health organizations' recommendations, it is not recommended to store Lipitor in the refrigerator. Instead, it should be stored at room temperature, away from direct sunlight and moisture.
