After researching, I found that Lipitor, a medication used to treat high cholesterol, can have several side effects at any dosage, including 70mg. According to the Lipitor medication guide from Drugs.com [1], common side effects include diarrhea, upset stomach, muscle and joint pain, and changes in liver enzyme levels.

More serious side effects may also occur, such as liver problems, muscle damage, and kidney issues [1]. Rhabdomyolysis, a serious condition that causes muscle tissue to break down, has been associated with Lipitor and other statins [1]. However, it is essential to note that the risk is low, and rhabdomyolysis is rare [1].

Lipitor may also cause an increased risk of developing type 2 diabetes, although the overall risk is relatively low [1]. The risk may be higher in patients taking higher doses of Lipitor [1].

Furthermore, DrugPatentWatch.com states that Lipitor has been associated with cognitive side effects, including memory loss and confusion [2]. However, it is essential to note that these cognitive side effects are not listed in the Lipitor medication guide from Drugs.com [1].

In summary, specific side effects associated with 70mg Lipitor include diarrhea, upset stomach, muscle and joint pain, and changes in liver enzyme levels. More severe side effects, such as liver problems, muscle damage, and kidney issues, may also occur. Additionally, Lipitor has been associated with an increased risk of developing type 2 diabetes and cognitive side effects, such as memory loss and confusion.
