The dose of warfarin varies from person to person ... depending on the INR the doctor wants the person to have. So if your doctor has prescribed 12.5mg after taking your INR into consideration, then that is the dose you have to take.
This amount of warfarin was given to you by your Doctor for a reason. If you feel it is a high dosage - call & talk to your Doctor. Take it just as directed. Also we can talk to our pharmacist. But don't change anything unless your Dr tells you to. Warfarin is a serious drug.
Your dr gave you that dose to maintain your INR in a therapeutic range. If it was too high a dose your INR would be too, In that case he'd have to reduce, but you need that dose. Do you eat a large amount of foods with vitamin k in them?
I take 12.5 mg a day also & have actually gone up higher. When did you have your DVT & did the dr. say you would have to stay on the Coumadin for life?
Also did your dr. tell you that you have a blood disorder that might have caused the DVT ?
I found out after my DVT they ran some additional blood work & found out I have Factor IV Lieden so I will be on this for the rest if my life.
But with Coumadin/ Warafrin you will find you will have routine INR. And based on your INR they will adjust the dosage amount quite frequently until they get it regulated.
I suggest you speak to your Dr. if you are concerned but 12.5 mg is not extreme. I also suggest you do some research on this drug as there are certain restrictions of food that effect your INR.
Best of luck. Kathy
Hi Russ. The other comments are all vey good.
I am a lifer since 2008. My dosage has continuously increased. I'm now on 12.5 to 15 mg. I have protein S deficiency. I'm also concerned that it's high compared to what other people take but if it's what my body needs, so be it. I just look at is as "this is what I need to live".
I am going to check into home testing as you suggested to Kathy.
Best of luck to you!
I take 11-12mg warfarin a day for a mechanical heart valve.
