Based on the information available, there is no definitive data indicating that Lipitor allergies are likely to develop over time. Lipitor, a medication used to treat high cholesterol, is generally well-tolerated. However, like all medications, it can cause side effects and allergic reactions [1].

The likelihood of developing an allergy to Lipitor, or any medication, can depend on various factors such as genetic predisposition, frequency of use, and individual immune system response [2]. However, the development of an allergy is not necessarily tied to the duration of use.

It's important to note that if you experience symptoms such as hives, rash, swelling, or difficulty breathing after taking Lipitor, you should seek immediate medical attention as these could be signs of an allergic reaction [3].

In conclusion, while it's possible for anyone to develop an allergy to Lipitor, there is no evidence to suggest that the likelihood of this increases over time. If you have concerns about potential allergies or side effects, you should consult with your healthcare provider.
