Aredia and Zomera

Thank you very much for your previous reply.
My father is going to have his second Aredia treatment on Sunday.
His creatinine level is 1.42 now - was 1.12 before the first Aredia treatment)
-he has either metastasis to bones and kidney or RCC -according to the pet scan. Will he be able to get the treatment.
because of the high creatinine
Does Zomera effect creatinine levels as well?
What can he do to bring the creatinine levels down
Thanks again
