Lipitor, also known as atorvastatin, is a medication used to treat high cholesterol levels. According to Drug Patent Watch [1], it is a statin drug that works by blocking an enzyme that produces cholesterol in the liver. While dizziness is not a common side effect of Lipitor, it is possible. A study published in the National Center for Biotechnology Information [2] found that dizziness is a rare side effect of atorvastatin, with only 0.1% of patients experiencing it. However, if dizziness does occur while taking Lipitor, it is recommended to consult with a healthcare provider to determine the cause and appropriate treatment.

Dizziness can have various causes, as reported by Everyday Health [3]. It can be a symptom of dehydration, low blood sugar, or an inner ear problem, among other things. It can also be a side effect of certain medications, including Lipitor. Dizziness during yoga could be caused by a lack of hydration, low blood sugar, or changes in blood pressure due to certain poses. It is important to stay hydrated and nourished before and during yoga practice, and to consult with a healthcare provider if dizziness persists or worsens.
