(female) I am taking coumadin for the rest of my life,Is there any thing that will stop the hair loss?
There are many potential causes of hair loss and you need to be evaluated for the cause of your loss. In your question, you are assuming the hair loss is related to the drug Coumadin (warfarin), but that may not be the case. Get a complete medical work-up for hair loss first. Coumadin is clearly important for your life, so that is not an variable that you can control.
Both myself (25) and my dad (57) are on warfarin for life due to a blood disorder (missing proteins in blood) and neither one of us has ever had any hair loss issues, do not recall seeing or hearing about this as a side effect, but I would go along with the recommendation of getting a second opinion on that.
