When my INR went to 6.4 a few months ago I had to withhold my dose for two days and my regular dose was changed also. But that was a big jump. In your case, as it's not too high, I would imagine that withholding your dose like that would make your INR fluctuate.
I am just wondering why they have you take 7.5mg one day and 10mg the next? It seems like a bit of a jump to me...When I have changes in my dose, it is usually only by 1mg per day, at the moment I am on 7/8/8mg every 3 days. (Although I've been on warfarin a year and a half and my INR still fluctuates frequently).

The pills I take are 5 mg of generic warfarin, so when it's adjusted it's by 2.5 mgs - or half a pill, and then they vary the days instead. So that's why it goes from 7.5 to 10 mgs on alternating days. For a while, I was doing 10 mgs more often than 7.5 - and I still had a low INR. This is just the dosing we landed on that (did) keep me steady. Honestly though, that's a really good question that I'll have to ask next week. Maybe they don't want me to hassle with prescriptions for 2 different pill sizes? Hmm.

Yeah, that's interesting. It's a little different here. You can get the warfarin tabs for whatever amount of mg you need, although they don't do half sizes. So rather than a 7.5mg tablet I'd take 7 or an 8mg tablet.
I hope your INR result works out ok!

And we're advised here not to half the pills either. It's just a different method, but I guess the important thing is that it works :)

My doc told me missing 1 dose would drop my INR 1 point. When I was too high, we dropped 1 dose and it did drop 1 whole point from 3.7 to 2.7.

Just my experience.

Interesting about the half-pill: I have a pill splitter, and the pill itself is scored, but some days a half ends up not exactly "half" but a little more or less. I can see the benefit of not using half pills.

I think that was a good approach LL, just doing and seeing how it goes, and then if it completely dumps your INR into the toilet, you'll have that knowledge and ammo when it happens again and they tell you to skip a dose.

My INR has been a little inconsistent since going off of warfarin for a colonoscopy back in June. Ever since, it just never got completely back on track with the same dosage that had kept me therapeutic for almost 2 years straight. Just never got back on track. So my latest dosage had been 13mgs 3 days a week and 14mgs 4 days a week, and that had me steady for about 8 weeks. Now my INR jumped to 3.1, which isn't that high, but my doc wants me to down to 13mgs 7 days a week. I think that's a total over correction. So I was thinking maybe just going 13mgs 4-5 days a week and 14mgs the other days of the week and just letting him know I made the change after testing in two weeks.

But, after thinking about it, I've been seeing my current doc for a couple of years, and he's been a champ at managing my warfarin in general, and so I'll go his route, see how it goes, and then we address it again if it gets mucked up.

I've totally accepted that my life is going to be a series of INR struggles and dosage adjustments, some of which may seem a little weird. My only request of my doc is that he doesn't kill me. So far so good.

I do half tabs all the time. I split 2s when I'm doing 13mgs. I just break them via the score mark. Not perfect, but not all that of a difference maker if it's not cut exactly.

Yep, I do the half tabs too. My doc wanted me to alternate days with 6mg and 7mg. But I have 1mg pills that I can split in half and wondered if it would just be easier to do 6.5 every day. She thought that would be fine too and it is less for me to remember every day.

I've currently got prescriptions for 5mg, 2mg, and 1mg pills. My INR has been up and down since March, so it gives me some flexibility in dosing.

Nice! Plus you get to test your own INR, Toss, so you've got a lot of control.
Maybe, someday....

Ah, yes, control. Isn't that what we all want?

I do love my home INR tester. After years of waiting 24+ hours for INR results, getting them in five minutes seems a little like magic.

And I love my doc too. Really, all things considered, this whole INR situation is so manageable and so NOT stressful that I really don't worry too much about it at all any more. Getting the CoaguChek was a little bit like regaining some freedom from being a "sick" person. Fewer trips to the doctor's office. Fewer worries about when to test or where to test or whether my lab had standing orders or whether I could get extra tests if I'm sick or taking antibiotics or whatever. Just less to worry about altogether.

More time to spend on the rest of my life...

I take 7.5 mg, 5 days a week and 10 mg the other 2 days. Because of dosage adjustments, I have way too many 10mg tab's and not enough 5's. So I am currently taking nothing but 1/2 tabs, 5 days a week.... 1/2 x 10 plus 1/2 x 5mg = 7.5 mg. Thank goodness they taught me fractions in elementary school!:-)

Update: After holding that one dose, this weeks INR is still at 3.1, so barely a budge. Just when I thought I knew my INR...
Anyhow, we're switching to just one day, Friday, that I'll do 10 mgs, and retest in 2 weeks to see what happens.

Ha! Well, it did budge only a bit, but so much for what we all think we know!

This whole thing is just one big crap shoot. I've never seen a more what appears to be unscientific science than warfarin management.

You got that right sister. I really have made no stinkin' changes to anything I do/eat/breath/etc. I wonder if I'll ever quit being surprised by this.
