Can I take my regular multivitamin pills while on warfarin?

Most multivitamin products contain vitamin K and thus do interact with your warfarin. You can take these multivitamin products that contain vitamin K as long as you are consistent (being consistent means that the multivitamin must be taken every day). For those who might not remember to take the multivitamin every day, options are still available. Some multivitamin products are available without vitamin K.

You should not start taking multivitamins while you are taking warfarin without first talking with your doctor. Talk with your doctor and pharmacist before taking any medicines (both prescription and over-the-counter), vitamins and nutritional or herbal supplements because they could interfere with your warfarin.
