Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels and reduce the risk of heart disease. Like all medications, Lipitor can cause side effects. According to the NHS [2], common side effects of Lipitor include headache, feeling sick, diarrhoea, constipation, and muscle and joint pain. These side effects are usually mild and go away on their own. However, if they persist or become severe, it is important to speak with a healthcare professional.

In rare cases, Lipitor can cause more serious side effects. The Mayo Clinic [3] notes that these can include liver problems, muscle damage, and an increased risk of diabetes. Signs of liver problems include yellowing of the skin or eyes, dark urine, and stomach pain. Muscle damage can cause weakness, pain, and tenderness. If you experience any of these symptoms while taking Lipitor, it is important to seek medical attention right away.

It is also worth noting that Lipitor can interact with other medications, including some antibiotics and antifungal medications. Drug Patent Watch [1] explains that this can increase the risk of side effects or reduce the effectiveness of the medication. Therefore, it is important to inform your healthcare provider of all medications you are taking before starting Lipitor.

In conclusion, Lipitor is a medication used to lower cholesterol levels and reduce the risk of heart disease. While most side effects are mild and go away on their own, some can be more serious. It is important to speak with a healthcare professional if you experience any symptoms while taking Lipitor. Additionally, it is important to inform your healthcare provider of all medications you are taking before starting Lipitor.
