Started Warfarin in March and have a target range of 2-3 and have APS. I was doing well for several weeks then fell below 2.0 for two weeks then in range again for 5 weeks and now for last two weeks with 3 venous blood draws, have been 1.7 -dose increased 42 to 43 mg per week then reading 1.8 and dose increaseed to 45.5 mgs or 6-1/2 mg per day and today 1.6 and increased to 7 mg per day. When it was steady I was just eating a couple of pieces of broccoli and a couple of cauliflower then started a very small amount of lettuce instead. I'll try the broccoli again but otherwise have been so very careful to keep general vit k levels steady. I'm new at this but find it very upsetting. Haven't introduced any new meds but started exercising a bit more.
I really get frightened that I'll have another stroke if it gets too low.
I live in New York City in the U.S.
