Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the body. According to the National Health Service (NHS) [2], the recommended dose of atorvastatin is usually once a day, with or without food. It is best to take it at the same time each day, as this helps to maintain a consistent level of the drug in the body. The dosage may vary depending on the patient's age, medical history, and other medications they are taking.

The frequency of taking Lipitor is not specified on the Drug Patent Watch website [1], but it does provide information on the drug's patent expiration and its availability in generic form. GoodRx [3] also provides information on atorvastatin, stating that it is usually taken once a day and that the dosage may range from 10 to 80 milligrams, depending on the patient's needs.

It is important to follow the instructions provided by the prescribing healthcare provider and to not exceed the recommended dosage. It is also important to continue taking Lipitor even if the patient feels well, as stopping the medication abruptly can cause cholesterol levels to rise again.

In conclusion, Lipitor (atorvastatin) is usually taken once a day, with or without food, at the same time each day. The dosage may vary depending on the patient's needs and medical history. It is important to follow the instructions provided by the prescribing healthcare provider and to continue taking the medication as directed, even if the patient feels well.
