Lipitor, also known by its generic name atorvastatin, is a commonly prescribed medication used to lower cholesterol levels in the body. Proper storage of Lipitor is essential to maintain its effectiveness and ensure its longevity. Based on the provided sources, here is how Lipitor should be stored:

1. Temperature: Lipitor should be stored at room temperature, which is typically around 68°F to 77°F (20°C to 25°C) [3]. It is important to avoid exposing the medication to extreme temperatures, such as excessive heat or cold, as it may affect its stability and potency.

2. Moisture: Lipitor should be kept in a dry place to prevent moisture from damaging the medication. It is recommended to store the medication in its original packaging, which is designed to protect it from humidity [3].

3. Light: Lipitor should be protected from light exposure, as it can degrade the medication. It is advisable to keep the medication in its original container, which is typically made of opaque material to shield it from light [3].

4. Childproof container: Lipitor should be stored in a childproof container to prevent accidental ingestion by children. Ensure that the container is tightly closed and placed in a secure location out of reach of children [3].

5. Avoid bathroom storage: Although it may be convenient, storing Lipitor in the bathroom is not recommended. Bathrooms often have high humidity levels due to showers and baths, which can impact the stability of the medication [3].

By following these storage guidelines, you can help maintain the quality and effectiveness of Lipitor over its shelf life. It is important to note that if you have any specific concerns or questions about storing Lipitor, it is always best to consult with your healthcare provider or pharmacist for personalized advice.
