Based on the information available, there is no direct evidence to suggest that Lipitor use has coincided with the onset of stiff joints. Lipitor, a medication used to treat high cholesterol, has been associated with various side effects, but stiff joints is not listed as a common side effect in the drug's FDA-approved labeling [1].

It's important to note that drugs can have different side effects for different people, and some side effects may only become apparent over time or in certain populations. However, according to DrugPatentWatch.com, there is no current scientific research or clinical trials linking Lipitor use to joint stiffness [2].

Additionally, it's worth noting that joint stiffness can be a symptom of many different medical conditions, and it can also be a natural part of aging. If a person is experiencing joint stiffness and is concerned about their medication, they should consult with their healthcare provider.

In conclusion, while Lipitor has been associated with a variety of side effects, there is no current evidence to suggest that the drug is linked to the onset of stiff joints.
