I just found this site. I was diagnosed with ovarian cancer Nov 2015, stage 3C. After surgery I did 18 weeks of chemo in 2016. Then Feb. 2018 another 5 chemo treatments. I'm on Zejula for 2 months now. Im BRCA II positive. The nausea is worse than any I had with chemo. I gag multiple times a day. I take it at night. My doc reduced my dose from 300mg to 200mg 3 days ago. Nausea still bad. Anyone had a dose reduction? How long before nausea improved. I took this stuff for 4 weeks before the nausea hit. I thought I had lucked out on the nausea side effect but no-can-do!
