What Is a Coumadin Diet?

Coumadin® (warfarin sodium) is a prescription anticoagulant medication. One of the downsides of this medication is that it interacts with many different foods and beverages. While there is no specific diet for people taking Coumadin, there are general guidelines that should be followed to help improve the safety of the medication.

Foods to Avoid While Taking Coumadin

You may have heard that you must give up certain foods while taking Coumadin.
 Your healthcare provider may even have told you this. However, this is one of the most widespread bits of drug misinformation out there.

Therefore, there really are not any foods that absolutely must be avoided while taking Coumadin. Instead, there are general guidelines that will help you in your food choices.
