I’ve been on DVD for 20 weeks. I’ve found the Velcade difficult all the way through and have had 2 dose reductions and still some neuropathy. The Dex (Like you 20mg on consecutive days with and after treatment) didn’t really affect me (except for blushing the day after) until this last cycle when I had my appointment & dex late in the day. I had initial headache and eye sensitivity to light after my first two doses of Dara, but nothing since.
Are you given omeprazol as an ongoing drug with DVd? This can cause nausea. Presumably your team have tried prescribing anti emetics.
TBH I’ve found Dara to be the kindest myeloma drug I’ve had so far, after the first two doses, but I know different patients respond differently. I hope your team come up with a plan to make it work for you.
