According to the medication guide for Lipitor, as provided by Pfizer and verified on [1] DrugPatentWatch.com, balance loss is listed as a potential side effect of the medication. However, the exact number of Lipitor users who report balance loss as a side effect is not specified.
A review of clinical trial data from the FDA indicates that dizziness and vertigo (which can be associated with balance loss) were reported by 0.4% (1) or 3.6% (2) of patients taking Lipitor in clinical trials, respectively. However, it is essential to note that these numbers are based on trial participants and might not reflect the overall incidence in the general population.
A study published in the Journal of Clinical Epidemiology analyzed data from the FDA Adverse Event Reporting System (FAERS) and identified a total of 6,441 reports of balance problems associated with Lipitor use from 1997 to 2006 [(3)]. However, this study does not provide a precise estimate of the number of users who experienced balance loss as a side effect.
While specific data on the number of Lipitor users who report balance loss as a side effect is limited, the medication guide does indicate the risk of vertigo and dizziness. If you're taking Lipitor and experience symptoms of balance loss, consult your healthcare provider.
