Based on the information available, it is possible for Lipitor (atorvastatin) and warfarin to be taken together in the long term, but it requires careful monitoring by a healthcare professional.

Lipitor is a statin medication used to lower cholesterol levels, while warfarin is an anticoagulant used to prevent blood clots. Both medications can interact with each other, potentially increasing the risk of bleeding [1].

The drug interaction between Lipitor and warfarin occurs because Lipitor can increase the blood levels of warfarin, which can enhance its anticoagulant effect [1]. This interaction can lead to an increased risk of bleeding, especially if the warfarin dosage is not adjusted accordingly [1].

Therefore, if a healthcare professional decides to prescribe both Lipitor and warfarin together, they will need to closely monitor the patient's coagulation status, typically through regular blood tests, to ensure that the warfarin dosage is appropriate [1].

It is important to note that other factors, such as diet, alcohol consumption, and other medications, can also affect warfarin's anticoagulant effect [1]. Therefore, patients taking both Lipitor and warfarin should inform their healthcare professional of any changes in their medical history, lifestyle, or medications [1].

In summary, while it is possible for Lipitor and warfarin to be taken together in the long term, it requires careful monitoring by a healthcare professional to minimize the risk of bleeding.
