I take my every night about 9pm. You do not have to take it with food. My blood specialist told me it didn't matter when I took it as long as I kept the time consistent. When I was in the hospital they tried to give it to me at 5pm but I thought that is because that's when all the other patients were getting their meds when their supper came. I still took mine at 9pm in the hospital.
I have not heard of taking coumadin at a specific time of day. I take mine in the evening usually between 6 and 8. Sometimes I'm at work and it might be a little later but never past 9:00pm. When I've been in the hospital I've noticed all meds are dispensed at a specific time, probably to make it easier on staff.
I have a mechanical heart valve under the care of 3 cardiologists. I was ordered to take my Coumadin at 9:00pm for good reason. Say you have a pt/inr drawn, and when your cardiologist gets the results your INR is too high. This is dangerous, so by taking this stuff in the evening it gives your doctor time to get in touch with you with orders to hold your dose off. Please be very careful with this poison, as it has almost killed me twice. I hate it, and after 10 years of using it, I really feel like I'm losing my mind. My doctors don't want to hear it, I went to a psychiatrist over it, and he is an M.D., so of course he dismissed it as "delayed anxiety" and wrote me for 60 Valium tablets. Then he sent me to one of the psychologists who work within his association. This man couldn't understand why I was going through this Coumadin fear after 10 years of use. I got a pat on the back and a "trust your doctor's" lecture.
No one cares! Now I really feel totally alone, no one here has answered me, I'm wasting my time. So I'm thinking of using the Coumadin one more time…..every tablet I have all at once. And after 10 years I have quite a supply…...
I have had two doctors tell me to always take it in the evening because if I take it in the morning before bloodwork it will make my inr/pt appear higher than it really is. But I'm no doctor so I don't know if that's true. Anyway I stay up late so I take mine at 2 am before I go to bed.
OMG people!! Talk to your doctors!
I've asked many doctors (nurses and pharmacists) this exact same question only to receive the same answer.
A) Coumadin (or Warfarin) is (basically) a "TIME RELEASED" medication. In other words it doesn't start working right away. This is also why sometimes the doctor will ask you to repeat your bloodwork "in a week" or "in two weeks" because it takes time to start working!! If you ever have surgery, you will need to switch medications only because it has the delayed reaction and need to be able to counteract if necessary.
B) you should take it around 3:00 - 5:00 pm because your blood work should be drawn in the morning (I do mine no later 9:00am - because my DR told me to do that) and this will give the most accurate reading. So if you've taken your Coumadin at 9am and draw your blood at 9am, it's either starting to wear off or it is at it's highest and will not give your doctor the correct numbers.
C) you don't HAVE to take it with food. But keep in mind that certain foods interact with the drug. As I am sure you all know to monitor how much 'dark leafy greens' you consume as well as any multi-vitamins. Vitamin K will REDUCE the affect of the drug and will therefore INCREASE your chance of forming a clot, which is probably the number one reason why your doctors will monitor your levels so often. Unless you eat the exact same foods every single day...
D) TALK TO YOUR DOCTOR or pharmacist! No one knows your medication (cause and effect) better than they do. And as I am not a DR nor a pharmacist, I could be incorrect. I would also advise you to ask your questions again and again until you fully understand the answers. Remember, there is no such thing as a stupid question!
