I'm new to this site. I've been living with lupus for 6 years but only recently have I been getting complications with kidneys. Kyle rheumatologist and nephrologist, though they are great doctors, have different views on how to treat my lupus. The nephrologist wants to put me on cytoxan but my rheumatologist says that staying consistent with cellcept, I won't need to go onto cytoxan. What should I do? I have read that cytoxan affects your ability to bear children. And I would like to have kids one day. Should I listen to the nephrologist and go on cytoxan and risk becoming sterile, or risk staying on cellcept and possibly go into renal failure/ dialysis?
