Lipitor, a medication used to lower cholesterol levels in the blood, should be stored at room temperature away from moisture and heat [1]. According to Baystate Health, medications should not be stored in the refrigerator unless it is specified in the medication's instructions [2]. Storing medications in the refrigerator can cause them to lose their effectiveness or break down, which can lead to potential health risks [3]. Therefore, it is not recommended to store Lipitor in the fridge. It is best to store Lipitor at room temperature in a dry and cool place, away from direct sunlight, moisture, and heat sources [1].
