Lipitor is a medication that is used to lower cholesterol levels in the body. According to Drug Patent Watch [1], the recommended starting dose of Lipitor is 10-20 mg once daily. The dosage can be increased to a maximum of 80 mg once daily, depending on the patient's response and tolerance.

It is important to monitor Lipitor for potential drug interactions, as some medications can increase the risk of side effects. The New Zealand Medicines and Medical Devices Safety Authority, Medsafe, recommends that healthcare professionals monitor patients taking statins, including Lipitor, for potential muscle-related adverse effects [2]. These effects can include muscle pain, weakness, and, in rare cases, a serious condition called rhabdomyolysis.

According to the National Center for Biotechnology Information [3], patients taking Lipitor should be monitored for potential interactions with other medications that can increase the risk of muscle-related adverse effects. These medications include fibrates, cyclosporine, and some antibiotics and antifungal medications.

In summary, Lipitor should be monitored for potential interactions with other medications, especially those that can increase the risk of muscle-related adverse effects. Patients taking Lipitor should be monitored for muscle pain, weakness, and other symptoms that could indicate a potential problem. It is important for healthcare professionals to be aware of potential drug interactions and to adjust the dosage of Lipitor as needed to minimize the risk of adverse effects.
