This is exactly what I read in The Coumadin (Warfarin) Help Book. Since my husband has been taking his Warfarin before his evening meal & his INR has been keeping fairly level. And that's good news, we want no more Strokes.
You should contact your caregiver for advice regarding your medication as they would have your medical history, general health, etc. There is a noted drug interaction with Viagra and warfarin in certain patients. In patients who have pulmonary hypertension, there is an increased risk of bleeding when taking these medications together, etc..
Thanks for your question, take care.
I been on warfarin for the past 18 yrs would viagra be alright to use.
Information from the NYU Medical Center:
The most important thing to do is to take it at the same time each day. Ideally you
should it in the evening, but choose a time of day that you will remember to take
it. On the days you are getting your INR level checked, do not take the warfarin
before the blood test in case a change in your dosage needs to be made.
Should I take warfarin with food or on an empty stomach?
Warfarin (Coumadin®) should be taken on an empty stomach, either one half hour
before or one hour after a meal. Food impairs the absorption of the drug. It is okay
to take it after a light snack, but don’t take it after a full meal.
Hope this helps and thanks for the question. Take care..
