While on Darbepoetin for a year, I took voriconazole. The 2 side effects I dealt with were vision issues and fluid build up in my legs. Neither side effect was that bad. The fluid build up was managed by wearing compression socks. I learned to like the socks and kept trying socks with different levels of compression until I found the best socks. The socks can get expensive and the higher compression socks are difficult to get on and off without help.
The vision issue was seeing blinking bright lights. It was like when sun shines through the trees while you are driving. I helped if I closed my eyes (avoids the dizzy feeling) and would last under 30 minutes.
When the Darbepoetin stopped working, I stared chemo (Vidaza). After several months of Vidaza, I was able to drop the voraconazole.
Wish you the best,
