Did you mean that you ARE comfortable splitting pills? Sorry, it’s 4 am, I may have missed something....
I also (briefly, thank god) had a Coumadin clinic that wouldn’t prescribe different dosages and insisted I add or subtract half a 5 mg pill a week depending on whether I was above or below range... I have since discussed this with a couple pharmacists who suggested that
1. Coumadin clinics are trained to think that you’ll get all confused if you have more than one dosage amount.
2. The 5 mg pills are more commonly prescribed than other dosages, so they are cheaper than say 6 mg or 1 mg.
Incidentally, I have spent 30+ minutes just waiting on the phone with a Coumadin clinic ‘technician’ while she tried to calculate what my new dose should be once when I was out of range. This when I was only allowed 5 mg pills... I wonder if a third reason for this difficulty getting other dosages could be the technician needing to think differently about calculating daily dosage?...
Maybe your clinic or cardiologist would be more supportive if you told them exactly how you plan to calculate a new dose when you’re out of range. (That’s IF that’s the plan - of course, they could still give you 1 mg pills to have on hand while ‘managing’ your INR for you (telling you how much to change warfarin dosage by when out of range) - but even if you want to rely on letting them tell you how much to adjust by, it might be good to calculate it yourself and then compare that to what they tell you.
I thought I would be able to rely on my Coumadin clinic, and guessed they’d be better at it than me (especially in the beginning); but I ended up having no choice but to self-manage after they NEVER called me back, on two occasions, to tell me the dosage change; and they were just generally too incapable, unresponsive and disinterested. It’s like someone else on this forum (probably Chuck C or pellicle) has put it - it matters more to YOU than to them because it’s your body and your life - your consequences if it’s not done correctly. Having said that, if they are capable and will prescribe 1 mg pills and you want to rely on them rather than self-managing, I get that too. We are all in different circumstances. I wish you luck.
