What is a common side effect of Atorvastatin?

Atorvastatin, a medication commonly prescribed to lower cholesterol levels, is part of a class of drugs known as statins. One of the notable side effects associated with statin use is myalgia, which refers to muscle pain or discomfort. This side effect arises because statins can impact muscle tissue, leading to symptoms such as a general feeling of muscle ache, weakness, or cramping. It is important for patients on atorvastatin to be aware of this potential side effect, as it may significantly affect their quality of life and adherence to the medication regimen.

The other options may occur in patients taking atorvastatin, but they are less specifically associated with the medication. For example, nausea and headache can be common side effects of a variety of medications and conditions, while dizziness might also arise due to a range of factors unrelated to statin use. Myalgia, however, is more distinctly linked with statin therapy, making it the most pertinent answer in this context.
