Hello all. I need to go on IV's on Monday & it seems the only thing I am not resistant to in one of my PA strains is colistin. I remember my former CF doc once telling me that IV colistin was "nasty stuff," & my current doc tells me there are some bad neurological side effects from it. So, I am a nervous wreck & would really appreciate to hear from those of you who have done IV colistin. What side effects did you have? How long before they went away? Anything else I should know about? Thanks in advance for any input you can give me. I am so scared.
