How is warfarin taken?
The clinician who is responsible for managing your warfarin therapy will tell you exactly how to take it. If the instructions are not perfectly clear, ask your clinician to explain the instructions again or to write down the instructions for you. Once you clearly understand the instructions, take your warfarin exactly as your clinician instructs you. Often times the dosage schedule may require taking different doses on different days of the week. This is required to "fine tune" the weekly dose of warfarin to meet you needs.
A stroke is an interruption of the blood supply to part of the brain caused by either a blood clot (ischemic) or bleeding.
If you are used to taking fewer than 5 mg of warfarin per day, you may wonder how you could use 65 mg tablets, since it is difficult to break the tablet into more than 7 pieces.

So, your clinician may consider having you take about the same amount of warfarin each week using different daily doses that are feasible with the larger, dye-free tablet.
Herbal medicines and supplements can also interact with warfarin. You should therefore avoid taking them without first checking with your GP, pharmacist, or staff at your local anticoagulant clinic.

A pulmonary embolism (PE) occurs when a piece of a blood clot from deep vein thrombosis (DVT) breaks off and travels to an artery.
Although there are now three new anticoagulants that don''t require regular monitoring – rivaroxaban, apixaban and dabigatran – most people who need an anticoagulant will be prescribed warfarin.
