My Equilibrium INR Has Risen Under Lockdown

For something like four years my Warfarin regime has been to take 4 mg.  every day and to self test every Monday and Friday. It has been a simple regime that has worked well and my INR has stayed between two and three, with 2.4-2.6 being the common readings.

In other words what I would call as a Control Engineer, my equilibrium INR is spot on.

In the past, I have noticed that in times of hot weather my INR  has tended to rise and in times of cold weather, it has occasionally dropped. A change of dose to three or five mg. has generally kicked it back towards 2.5 mg.

Doctors and this Control Engineer would say that you shouldn’t chase the INR by constantly changing the dose.

Warfarin also seems to have a cumulative property. A couple of years, I had to have a small operation. I dropped the INR to 2.1 for the operation over three days, by cutting back to 3 mg. After the operation three days at 5 mg. brought it back to 2.5.

Under lockdown, my equilibrium INR rose initially to 3 on a dose of 4 mg. every day.

In a telephone conversation with my GP, we agreed to alternate the dose between 3 and 4 mg. every day. My INR now seems to be stabilising between 2.5 and 2.8.

Why has my equilibrium INR risen under lockdown?

My house can get hot, as it wasn’t designed and built correctly and because of that I am drinking a lot of fluids. When I prick my finger for the self-test, the blood seems more watery than usual, so are all those fluids diluting my blood and causing my INR to rise?

Bodies can’t disobey the laws of physics!

Oh! For a walk by the sea in the sun!

  1. My blood glucose levels have dropped a lot. I have no idea why – my appetite isn’t great some days, but it is low regardless of that. 2 hours or so after my evening meal yesterday when I tested it was 3.8. Way too low, so near to bedtime. I So had to eat toast and jam – only a bit if jam though. The lifts the glucose quickly and then the carbs in the bread lift them slowly.

    They took e off one of my diabetic medications in hospital, and it was low in hospital too, but not as low as it is nowadays. If it continues I will lower the dose of my other medication.
