Hi ya, I've been having the same problem over the last month or so and was going to ask the same question! My INR has been difficult to get therapeutic since starting 5 mths ago now the last few weeks it's been high - 4.4, they've since reduced me back to 9.5mg from 12 so I'm hoping my hair might stop falling out now or at least slow down. I too have about 1/2 what I use to :-(. Going to doc next week so will quiz her.

How is ur INR? What dose r u on?

My INR has been fluctuating between 1.9 and 3.0.

Weird, because I am pretty much in range, but two weeks ago at 1.9 it seemed like I was losing hair still but it was getting lighter (I was so excited and thought it may be the end of this nightmare) and then this week, I am at 2.9 and last night I lost so much hair in the shower I wanted to cry.

Let me know if your doctor has any advice. This totally sucks. I just feel super self-conscience about it. When I run my hands through it, there isn't much there. :(

I'm losing hair as well. However, they say you won't go bald. I had very thick hair, so it doesn't really seem like a lot to look at me. But it upsets me that it's laying in the shower when I get out. I have always loved my hair. I've been around 2.4 for over a month now and it doesn't seem to make a difference.

I don't think INR has anything to do with it. Hair loss is a documented side effect of warfarin, for some people.

The same thing happened to me. About a month after starting warfarin, I noticed a lot of hair coming out in my hands when I washed it. For me, it has become more like a cycle, so I'm not losing it all at once, but for a couple of weeks I will, then it slows down for a month and then starts up, and I notice baby hairs coming in, even though I'm on warfarin. What helped me was keeping my hair trimmed more often and playing with my part, to make it look fuller. My hair stylist said she can tell I've lost some a little, but that it's not nearly as much as I perceive it to be.

Once you're off warfarin, the hair loss does stop.

Yep same here. Its really thin right now. I don't know what to do about it either. Right now I'm just trying to make it work with different hair styles and such. But I feel your pain!

Oh, I hope this doesn't happen to me!! I lost more than half my hair when I was taking the bc pills that helped me get into this mess in the first place! If the trend is the same though, less and less falls out over time, it's just that initial loss that's really shocking (and depressing).

I noticed my hair thinning some while just being on the Warfarin, but now that I have been hospitalized for 8 days and have been given STRONG IV steroids along with LOTS of other medications (including antibiotics) the hair loss is more apparent to me. I'm hoping that the oral steroid that they're putting me on tonight so as to taper me off steroids will make a difference.

Two things.
1) Yes, trauma and major stress can cause hair loss, and the lag is usually 6 weeks from the event. Stress can "shock" the hair follicles and they shut down for a while, but it takes several weeks for the new hairs to start growing in and they slowly push the old hairs out (hence, the delay in loosing it, varies depending on how fast your hair grows and duration of the stressful event).
2) There is some hope! I have had hair problems LONG before the PE. Originally diagnosed as genetic, but last year also discovered my thyroid was failing so it's hard to say for sure what the original cause was. That said, I saw a dermatologist who gave me a prescription for men's strength Minoxidil (rogaine). When I use it, it works really well. In all honesty, before the PE I was hap-hazard about using it. It makes my scalp itch something fierce, so I used to only put it on in the AM (should be used 2x a day), and sometimes gave myself a weekend off, etc. After the PE my hair started falling out much worse! My DH made comments and I was noticing it too, so I started using the Rogaine am/pm religiously and it has worked WONDERS! My hair hasn't been this thick since I was a teenager! I have to use dandruff shampoo, and sometimes topical anti-itch stuff, and I still give myself a weekend off here and there, but it's totally worth the effort and minor discomfort. Of course, I'm not a dermatologist so I can't tell you if it's OK for any of the other women out there to use the men's strength, but the men should try it for sure, and maybe the women should talk to their doc or derm about it.
Cheers!
