I have recently diagnosed with afib and was prescribed a blood thinner. I have a lot of allergies with meds, and I would like to know all names of the blood thinners and the ones with the least side effects. I am 74 years old and have thyroid disease, hypertension, fibromyalgia, had breast cancer, since cured. Will aspirin help as a blood thinner and what dosage? I am also disabled and can t pay for this consultation, so I will withdraw my questions. Thank you for the possible solution for my problem. Laura First of all it would be nice if I had the money, but I don t..Thank anyway sincerely
