Based on the available information, there is no direct correlation found between Lipitor dosage and swimming intensity. Lipitor, a medication used to treat high cholesterol, is a statin that works by blocking a substance your body needs to make cholesterol [1]. The dosage of Lipitor is typically determined by factors such as the patient's age, overall health, and the severity of their condition [1].

Swimming, as a form of exercise, can help lower cholesterol levels [2][3]. However, the intensity of swimming or any exercise, for that matter, does not directly influence the dosage of Lipitor or any other medication. It is always recommended to consult with a healthcare provider for personalized medical advice [1].

In summary, Lipitor dosage is not determined by swimming intensity. Swimming can help lower cholesterol levels, but it does not directly affect the dosage of Lipitor or other cholesterol-lowering medications.
