Lipitor is a medication that is used to lower cholesterol levels in the blood. According to Drug Patent Watch [1], Lipitor has been on the market since 1996 and is one of the most widely prescribed medications in the world. However, like all medications, Lipitor has potential side effects.

According to the Mayo Clinic [2], some of the most common side effects of Lipitor include headache, nausea, diarrhea, constipation, and muscle pain. In rare cases, Lipitor can cause serious side effects such as liver damage, muscle damage, and an increased risk of diabetes. The risk of these serious side effects is higher in people who take high doses of Lipitor or who have underlying medical conditions.

The NHS [3] also lists some potential side effects of Lipitor, including headache, joint pain, muscle pain, and an upset stomach. They note that these side effects are usually mild and go away on their own. However, they also warn that Lipitor can cause more serious side effects such as liver problems, muscle damage, and an increased risk of diabetes. The NHS advises people who experience any of these serious side effects to contact their doctor immediately.

In conclusion, while Lipitor is generally considered safe and effective, it can cause side effects in some people. The most common side effects of Lipitor are mild and go away on their own, but in rare cases, Lipitor can cause serious side effects such as liver damage, muscle damage, and an increased risk of diabetes. People who experience any of these serious side effects should contact their doctor immediately. It is important to talk to your doctor about any potential risks and benefits of taking Lipitor before starting the medication.
