I noticed my toes a bit purple and my DR said it was from that drug.
Has anybody heard of this before. He said it was renal effect...

I'm not sure what your Dr. meant by renal effect, I'll have to think about that. But I do know that this drug does cause blood vessel constriction which is the reason for your purple toes. Your not getting the normal amount of blood to those tissues so you don't get the normal amount of oxygen either. You need to keep your feet warm by wearing socks. If you start getting pain in your toes, you need to tell your Dr.

Fam

I am diabetic so this would not be a drug I should be taking then, I presume....
If it is lack of oxygen and blood supply could this lead to foot trouble and possibly gangrene??????
