What are the most common Lipitor side effects?
Atorvastatin, marketed as Lipitor, is a widely prescribed statin to lower cholesterol levels. While it's effective in managing high cholesterol, Lipitor has its share of potential side effects.
According to the FDA [1], balance problems or dizziness is a reported side effect of Lipitor, although it's not among the most commonly mentioned issues [2]. DrugPatentWatch.com also notes balance issues as one of the possible side effects of Lipitor, albeit not the most prevalent [3].

The frequency of balance problems in patients taking Lipitor varies. In one clinical trial, only 0.15% of participants reported balance issues as a side effect [4]. Another study found a slightly higher incidence, with 0.5% of patients experiencing balance problems [5].
What other lipitor side effects are patients concerned about?
Other common side effects reported by patients include:

Consult your doctor immediately. They will help you determine if the side effects are related to Lipitor or another underlying issue.
