Lipitor, also known as atorvastatin, is primarily used to lower cholesterol levels, not blood pressure. While it is not typically prescribed specifically for blood pressure, it may indirectly benefit heart health by reducing cholesterol levels. However, like any medication, Lipitor can have side effects. Common side effects include muscle aches, joint pain, diarrhea, and changes in some blood tests related to liver function. In rare cases, Lipitor can cause more serious side effects such as muscle breakdown, liver problems, and a rare but severe form of muscle damage called rhabdomyolysis. It is essential to consult with a healthcare provider before starting any medication to understand the potential risks and benefits specific to an individual's health condition and medical history.
