Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the body. Like any medication, Lipitor has potential side effects that patients should be aware of.

The dosage of Lipitor prescribed can vary depending on the patient's age, medical history, and other factors. According to Drug Patent Watch [1], the recommended starting dose for most adults is 10 mg per day, which can be increased up to 80 mg per day if needed. However, the maximum recommended dose for elderly patients or those with liver problems is 40 mg per day.

Some of the most common side effects of Lipitor, as listed by Drugs.com [2], include headache, nausea, diarrhea, muscle pain, and weakness. In rare cases, Lipitor can also cause more serious side effects such as liver problems, allergic reactions, and muscle damage. Patients should seek medical attention immediately if they experience symptoms such as dark urine, yellowing of the skin or eyes, unexplained muscle pain, or fever.

According to the NHS [3], Lipitor can also interact with other medications, so patients should inform their doctor of any other medications they are taking before starting Lipitor. Additionally, patients should avoid drinking grapefruit juice while taking Lipitor, as it can increase the risk of side effects.

In summary, Lipitor can have potential side effects such as headache, nausea, diarrhea, muscle pain, and weakness. Patients should be aware of the recommended dosage and seek medical attention if they experience any serious symptoms. Patients should also inform their doctor of any other medications they are taking and avoid grapefruit juice while taking Lipitor.
