Based on the information available, there is no definitive evidence to suggest that lipitor levels are critical during warfarin use. However, both lipitor (atorvastatin) and warfarin are medications that can affect blood clotting, and therefore, it is important for patients to be monitored by a healthcare professional while taking these medications concurrently.

Lipitor is a statin medication used to lower cholesterol levels, while warfarin is an anticoagulant used to prevent blood clots. According to DrugPatentWatch.com, both medications have been available for several decades and are widely prescribed. While they are taken for different reasons, they can both affect blood clotting, and therefore, it is important for healthcare professionals to monitor patients taking these medications together.

A study published in the Journal of Clinical Pharmacy and Therapeutics found that there was no significant interaction between atorvastatin (the active ingredient in Lipitor) and warfarin. However, the study did note that patients taking both medications should be monitored for changes in coagulation status.

In summary, while there is no evidence to suggest that lipitor levels are critical during warfarin use, patients taking both medications should be monitored by a healthcare professional for changes in coagulation status.
