Warfarin Sodium and migraines

I'm 39 and have been on Coumadin for about a month. Was diagnosed with DVT in right calf after taking Yaz birth control for only about 4-5 months (no other pre-conditions - I'm a non-smoker, fairly active, not overweight, no recent airplane trips or long car rides.) I was on Yaz to treat severe problems with my period which has been the case since I was a teenager, but I was tired of having to call in sick to work every month, and had hoped Yaz would eliminate that problem. I had been on other BCPs when I was in my 20's, and never had any symptoms of clotting, so didn't think that it would be all that risky to try again, despite me being slightly older than the typical woman on BCP. Obviously, I am not taking Yaz anymore, and will not be able to take any other hormonal therapies for the rest of my life. But I guess that's minor compared to the risk of developing PE from an undiagnosed blood clot.

Anyway, I've been noticing I've been getting sudden, severe headaches since starting the Coumadin. I have a history of migraines but I usually only get one or two per year at most. Now I've had what feels a lot like a migraine twice in a matter of a couple weeks. My husband has also commented that I've been irritable and acting "spacy".

My INR has also been all over the place. They've been alternating me between 5 mg and 7.5 mg per day. For the first few weeks I was right where they wanted me - between 2 and 3, but then last Friday my results were 4.6!! Way too high. I go back this afternoon to see if anything's changed over the weekend, after skipping a dose and then doing 5 mg Sat. and Sun. I do hope they can find the right balance and don't have to keep tinkering with the dosage. I'm wondering if that's what's contributing to the headaches. Maybe if they can stabilize how much I'm taking from day to day, my body will adjust.

I wonder if anyone "official" is tracking the number of DVT/PE patients that can trace their onset of symptoms to Yaz. My sense is that this is a much more serious and prevalent side effect than their marketing dept. would like to admit.....

I've been on Warfarin since Feb/04. I had 2 blood clots form in my leg and traveled in my lung and was dignosed with APS. At first I was on 12mg a day for about a year, now I am regulated at 10mg a day. For the last 2 months my INR count has been high (blood too thin) and was on 5 mg for 2 days in July/07 and then back to 10mg. This month Aug/07 my dr took me off my meds for 2 days, then back on reg 10mg. I will go back and check my INR in a few weeks.
I haven't experienced hair loss, but I have experienced migraines, weight gain (a lot!), blurred vision, black out with vision, and slight memory loss. And I am only 40 yrs old. Just wondering if you or anyone else has experienced any of these side effects.

I have been on Warfarin since December 2003 for peripheral vascular disease. I was on the same dosage, 7.5 mg, up until I started seeing a different DR. last year and he upped me to 9.5 mg a day. I noticed I started losing a tremendous amount of hair. Dr put me on prenatal vitamins with no improvement. Hair is very dry and brittle. Have had alot of lightheadedness to the point where I feel I want to pass out but don't, now it affects my driving and work. My head feels like it wants to explode sometimes and have lots of migraines. Anyone else????

I've been on Warfarin since June, 2004 after having a Pulmonary Embolism. At first no side effects. It took 2 years to regulate INR. I take 6mg per day. In the last year though, severe hair loss, bleeding in my lower legs (skin) when my legs swell. I am not able to store iron according to dermatologist that I saw for hair loss. I've just been diagnosed with APS, anti-phospholipid syndrome.
