What time of the day can I take my coumadin?

I'm a veteran, and get checked at the VA hospital.
In the hospital, after surgery, they started my Coumadin / Warfarin in the evening. After I'd been home a couple months, I asked my doc whether I could change to mornings. She said it makes no difference, as long as I take it at approximately the same time daily. I specifically asked, and she said taking the aspirin and coumadin at the same time makes no difference. The coumadin dosing doesn't 'jump' your INR levels up or down. It's a gradual thing, taking about two weeks on average. I mentioned the VA because I trust them immensely. Ask your doctor about these things. Also, I like researching everything. Between Drugs(dot)com, Mayo clinic page,Harvard medical, and a few others, I've learned a lot about conditions, drugs, treatments. Good luck.
Oh, I don't know that it matters but, I switched times because when I rarely miss meds, it's the evening bunch, having fallen asleep.

I have been taking coumadin daily since July 2005. I have always taken it in the evening. I also take a baby aspirin every morning. Even though I work different shifts any time of the day or night, I always take each at the same time, baby aspirin in the morning and coumadin in the evening. The coumadin I try to take within a two hour time frame (6-8pm). I don't see the problem in taking both at the same time, but you might want to ask your doctor.

Although it is not a critical issue, most physicians strongly encourage you to take warfarin (coumadin) in the evening. This is only because Protime blood tests are typically done in the morning and reported to the physician's office a little later. You find out your dose after this.
To be able to change the dose if needed as soon as possible it is best to take warfarin in the evening.

How well controlled are you?
Talk to your doctor about this - may be you could take the aspirin with the coumadin at 4pm.
