Understanding the Expiration Date of Lipitor

Lipitor, a popular cholesterol-lowering medication, has been a staple in many people's medicine cabinets for years. However, like all medications, it has an expiration date. But what happens to the effectiveness of Lipitor after it expires? Can it still have some effect, or is it completely useless? In this article, we'll delve into the world of expired medications and explore the answer to this question.

What is the Expiration Date of Lipitor?

The expiration date of Lipitor, also known as atorvastatin, is typically 3 to 5 years from the date of manufacture. However, this date is not necessarily a guarantee of the medication's potency or safety. The expiration date is determined by the manufacturer, Pfizer, and is based on the stability of the medication under normal storage conditions.

What Happens to Medications After Expiration?

When a medication expires, it doesn't suddenly turn into a useless substance. Instead, the active ingredients may degrade over time, reducing the medication's effectiveness. This degradation can occur due to various factors, including exposure to light, heat, humidity, and physical stress.

However, the study also noted that the medication's effectiveness decreased significantly after 3 years.

What to Do with Expired Lipitor
