My cardiologist suggested Coumadin (=Warfarin) rather than Plavix. These are both anti-clotting drugs, but work rather differently. Unfortunately, both cause the fragility of forearm skin, and result in difficulty of healing.
For a good discussion of the difference in the two drugs, see:

I have discovered a clotting substance (powder) that instantly stops bleeding of such superficial scrapes and abrasions. It is called, simply: UrgentQR. Made by biolife.com. It is available, non-prescription, on request from most major pharmacies (Walgreen, CVS). I can testify that it truly works (I have no stock in the company

) - it is non-allergenic. I would not recommend this for a major injury, but it forms an instant scab over a minor scrape such we tend to get. It is manufactured in Sarasota, FL, and I have recommended it to doctors and nurses - all have thanked me, since the manufacturer does virtually no marketing.
Just some advice to my slow-clotting sisters.
Hugs,
Lydia
