Hello. Welcome to HCM.
I have read your question and understand your concerns.

Whether to increase or decrease the dosage of coumadin depends on the disease from which he is suffering.

Different diseases have different target INRs.
Usually in mechanical valve replacement INRs target should be between 2.5 to 3.5.
In most of the other diseases target will be varied from 1.8 to 3.0.

So, ask your doctor what will be the target INR in your case and then your modify dose accordingly.

Thank you.
Have a nice day.
