I have undergone aortic valve replacement surgery in 2003. Until 2 months back I was taking 150mg Ecosprin and 5mg Warfarin daily, then I was diagnosed with Hepatitis E and my INR value increased suddenly, so my doctor cut on the warfarin for few days until it dropped to <1.5 and then I started taking my warfarin again but my INR didn't increase. 2 weeks back my doctor increased my dose from 5 to 6mg but still my INR value is 1.4 and it is not increasing from past 2 months.
Please help.
