Caverject - I will have to take Warfarin (Coumadin) for 2 months. Can I still use Caverjet or Edex?

I had already done that, no interaction. The question is related to Caverject/Edex as they relate to injections while on a blood thinner. Some web sites say that it is OK, others say it is not;apparently, even the doctors disagree. I do not want a hematoma, but, I don't know if that is a likely result or what the risk is-the reason for my question. Yes, I'll certainly ask my urologist, as asking a doctor is a true response to just about every question asked on this site, true enough.
