Lipitor is a brand name for the drug atorvastatin, which is a type of statin used to lower cholesterol levels in the body [1]. The duration of taking Lipitor depends on various factors, including the severity of the condition, the patient's response to treatment, and the doctor's recommendation.

Patients should only stop taking Lipitor under the supervision of a healthcare professional [3]. The doctor may gradually decrease the dosage or switch to a different medication depending on the patient's response to treatment [3].

In conclusion, patients should not stop taking Lipitor without consulting their doctor. The duration of taking Lipitor depends on various factors, and stopping the medication suddenly can lead to an increased risk of heart attack or stroke.
