I have a question about coumadin and INR. How long does it take for a dosage to effect INR and how long does the effect last.
Background:
I had an ablation on February 4. Prior to the ablation, I was given vitamin K to lower my inr (1.3) and put on a heparin drip. Following the ablation I was given 8mg of coumadin. February 5, INR was 1.4 and was given a dosage of 15mg. Feb 6, INR was 1.5 and was given another 15 mg. Feb 7 INR was 1.6 and was given another 15 mg. Feb 8 in the am my INR was 1.9. At this point I was released from the hospital and told to inject myself with Lovenox if my INR is below 2.0. When I arrived home (3:00) I checked and my INR was 2.3 so I did not take the lovenox. Yesturday, out of curiosity, I checked again and my INR was 1.9. I had taken my normal Sunday night 5mg does as directed. I called the surgeon and he said I should not check so often (HA!) and that it is ok not to take the lovenox. Continue with my normal dosages and check in a week.
I don't understand why my INR would drop so quickly.
