Lipitor is a medication used to lower cholesterol levels in the blood. It works by blocking an enzyme that produces cholesterol in the liver [1]. According to Drug Patent Watch [1], Lipitor's side effects may include muscle pain, weakness, and cramping. However, the sources provided do not mention dehydration as a side effect of Lipitor.

Dehydration occurs when the body loses more fluids than it takes in, leading to a lack of water in the body. Symptoms of dehydration include thirst, dry mouth, fatigue, and muscle cramps [2]. Hot yoga, a type of yoga practiced in a heated room, can cause excessive sweating and increase the risk of dehydration [2].

A study published in the Journal of Exercise Science and Fitness found that practicing hot yoga can cause significant dehydration in participants [3]. However, the study did not mention Lipitor or any other medication affecting dehydration symptoms during hot yoga.

In conclusion, based on the sources provided, there is no evidence that Lipitor worsens dehydration symptoms during hot yoga. While hot yoga can cause dehydration, it is important to stay hydrated before, during, and after the practice to prevent dehydration symptoms [2][3].
