Detailed Answer:
Hello,
Thanks for posting in HCM.
Warfarin 10mg is pretty high dose. Usually for other conditions we give 1, 2 or even 3mg and still patient comes to INR of 2 to 3 in about a week to 10 days period of time.
Any changes desired in INR occuring due to warfarin dose changes take about maximum 1 week time.
For valve replacement, target INR is 2.5 to 3.5. So I guess you are quitein your desired range and small increase in INR is required now.
Keep checking INR frequently as sometimes it will go very high and dose modification will be required. So keep tab on your INR levels after consulting your cardiologist for optimum INR levels.
I hope I have answered your question well.
If you have any questions kindly ask me back.
Thank you
