I had heart surgery two years ago, and I’ve been on this medication ever since. I haven’t had a problem with this at all, and absolutely no side effects. I have to have blood test done every six weeks, but my blood levels have always been within the normal range. My doctor has me taking 12.5 mg three days a week, and 10 mg for four days. Just watch out if you are taking it under the generic name warfarin. The drug is made differently by different companies, and Coumadin is the best.

My husband, now 72 years old, started taking Coumadin in August of 2009. This was to treat atrial fibrillation which had recently appeared. He never seemed to struggle breathing, and he was active enough to keep working. He saw a cardiologist for tests, and the doctor told him to take coumadin. When he started this drug, he became confused and forgetful, and he had weak legs too. This made him stop working. The dementia wasn't supposed to be a side effect, the doctor thought, so he kept changing the dosage to see if it would go away. In May of 2010 he had pneumonia and went to the hospital, where they made him stop taking Coumadin. Recently, however, he couldn't breathe, so an ambulance came and brought him to the hospital. They believed that he had a small stroke and perhaps pumonary embolisms. One doctor at the hospital told me that he should take coumadin, while the neurologist didn't think so. I was left with the impression that if I didn't put him on the coumadin, then I would be to blame if he died. He was currently on heparin and lovenox IV. At this point he was doing very well, active and walking and coherent. Three days ago they put him on 7.5 mg of coumadin and he suddenly went crazy. At 11 pm the nurse called and informed me that security had to restrain him and that they had to dose him with atavan. At this point they wanted to send him home, but I asked them to keep him for at least one more day because I knew that if he went ballistic, I wouldn't be able to keep him under control. The doctor didn't like that I took him off coumadin. When my husband did come home, he slept for a long time. He is confused, still. He is currently taking Levaquin, Lasix, and other anti-psychotic medications, but I won't give him those. He has 8 prescriptions to take while home. Next week we'll visit our primary care physician to see if we should do anything else.
