According to the sources provided, it is not recommended to freeze Lipitor (atorvastatin) for long-term storage.

The first source, Drug Patent Watch, provides information about the drug Lipitor but does not specifically address the issue of freezing. Therefore, it does not provide direct information on whether Lipitor can be frozen for long-term storage [1].

The second source, Verywell Health, discusses how temperature can affect medication stability. It explains that freezing medications can potentially alter their chemical composition and reduce their effectiveness. Freezing can cause changes in the drug's structure and formulation, leading to potential loss of potency or even harmful effects when the medication is used [2].

The third source, Mayo Clinic, provides general precautions for atorvastatin (the active ingredient in Lipitor) but does not specifically mention freezing. However, it is always recommended to store medications according to the instructions provided by the manufacturer, and freezing is not typically recommended for most medications [3].

Based on the information from these sources, it is advisable to follow the manufacturer's instructions for storing Lipitor and avoid freezing it for long-term storage. If you have any concerns or specific questions about storing Lipitor, it is best to consult with your healthcare provider or pharmacist for guidance.
