The best posts here to pay attention to regarding adjustment of warfarin based on INR are those posts by
@pellicle . He’s a guru when it comes to that stuff and I have learned an immense amount from his posts. Perhaps he’ll chime in here with some magic.
Some things to keep in mind …
- Medication changes can affect your INR
- Sickness can affect your INR
- Stress can affect your INR
- Exercise can affect your INR
- What you eat can affect your INR.
- You, as a unique individual, can affect your INR (your genetics, your age, etc)
Remember to dose your diet and don’t diet your dose. Eat consistently throughout the week and avoid the no-no foods that can cause issues: Cranberries, Pineapple, Grapefruit, Açaí berries. Definitely eat your greens - consistently. If you drink alcohol, do it consistently (or just have a single serving). There’s a lot more to say but I’m just mentioning some basics.
Another thing to keep in mind is that any dosage change will take some time to stabilize. Give it like 5-7 days to stabilize before making any further adjustments.
There IS a logical way (with maths) to monitor how your body and warfarin are interacting. I’ll leave that to someone else if they wish to jump on and explain.
