Lipitor is a prescription medication that was first approved by the US Food and Drug Administration (FDA) in 1996 [1]. It is available in tablet form and is taken orally [2].

According to the patient tips on Drugs.com, Lipitor has been effective in reducing cholesterol levels for many patients. However, some people may experience side effects such as muscle pain, nausea, and diarrhea [3]. It is essential to talk to your doctor about any potential side effects and to report any adverse reactions.

It is important to note that Lipitor's effectiveness may vary from person to person, and it is not a cure for high cholesterol. Lifestyle changes, such as a healthy diet and exercise, may also be necessary to manage cholesterol levels [2].

In conclusion, Lipitor is a medication that can be effective in reducing cholesterol levels, but its effectiveness may vary from person to person. It is important to talk to your doctor about any potential side effects and to follow a healthy lifestyle to manage cholesterol levels [2][3].
