Lipitor is a medication used to lower cholesterol levels in the body. It is important to monitor liver function while taking Lipitor to ensure that it is not causing any damage to the liver. According to the FDA, Lipitor can cause liver damage, and patients should be monitored for signs of liver injury [2].
The frequency of liver monitoring while taking Lipitor varies depending on the patient's risk factors. According to a study published in the Journal of Family Practice, patients with normal liver function and no risk factors should have their liver function tested before starting Lipitor and then again after 12 weeks of treatment. If liver function tests are normal, then testing can be done every six months [3].
However, patients with pre-existing liver disease or other risk factors may require more frequent monitoring. The FDA recommends that patients with a history of liver disease, heavy alcohol use, or liver enzyme elevations should have their liver function monitored more closely while taking Lipitor [2].
In conclusion, the frequency of liver monitoring while taking Lipitor varies depending on the patient's risk factors. Patients with normal liver function and no risk factors should have their liver function tested before starting Lipitor and then again after 12 weeks of treatment, with subsequent testing every six months if liver function tests are normal. Patients with pre-existing liver disease or other risk factors may require more frequent monitoring. It is important to consult with a healthcare provider to determine the appropriate frequency of liver monitoring while taking Lipitor [2][3].
