Lipitor is a brand name for atorvastatin, which is a medication used to lower cholesterol levels in the blood [1]. According to Drug Patent Watch, the most common side effects of Lipitor include diarrhea, joint pain, and nausea [1]. However, Lipitor may also cause more severe side effects, such as liver damage, muscle pain, and weakness [1].

Yoga is a physical activity that involves different postures, breathing techniques, and meditation practices [2]. According to a study published in the Journal of Ayurveda and Integrative Medicine, yoga may improve lipid profiles and reduce the risk of cardiovascular diseases [2]. However, practicing yoga may also cause some side effects, such as muscle soreness, fatigue, and injury [2].

Regarding the combination of Lipitor and yoga, there is no evidence of specific side effects. However, some people may experience muscle pain and weakness when taking Lipitor, which may interfere with their ability to practice yoga comfortably [3]. In this case, it is recommended to talk to a healthcare provider to adjust the Lipitor dosage or switch to a different medication [3].

In conclusion, Lipitor may cause side effects such as diarrhea, joint pain, and liver damage, while yoga may cause muscle soreness, fatigue, and injury. There is no evidence of specific side effects when combining Lipitor and yoga, but Lipitor's muscle pain and weakness may interfere with yoga practice. If experiencing discomfort, it is recommended to consult a healthcare provider.
