Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels and reduce the risk of heart disease. However, like any medication, it can cause adverse effects.

According to the National Health Service (NHS) [2], some of the most common side effects of atorvastatin include headache, diarrhea, constipation, nausea, stomach pain, and muscle and joint pain. These side effects usually go away on their own, but if they persist, it is recommended to contact a healthcare provider.

In rare cases, atorvastatin can cause more serious side effects such as liver problems, muscle damage, and an increased risk of diabetes [2]. Liver problems may cause symptoms such as yellowing of the skin and eyes, dark urine, and abdominal pain. Muscle damage can cause weakness, pain, and tenderness. An increased risk of diabetes may lead to symptoms such as increased thirst and urination, fatigue, and blurred vision.

Drugwatch [3] also reports that atorvastatin can cause memory loss, confusion, and cognitive impairment, although these side effects are rare. Additionally, the medication may interact with other drugs, such as antibiotics and antifungal medications, which can increase the risk of muscle damage.

It is important to note that not everyone who takes atorvastatin will experience these side effects, and the benefits of the medication may outweigh the risks for some individuals. However, it is essential to talk to a healthcare provider about any concerns or potential side effects before starting this medication.
