Varies with time: At first, INR is usually checked every 3-4 days until a dose is found that keeps you in the appropriate INR range for 2 or more checks, then checks are spaced out to weekly. With a couple more normal checks, they can be moved to every 10-14 days, then ultimately if your dose is very stable over time and you do well at maintaining a consistent warfarin-diet, monthly checks are fine long-term.
