My mom's potassium is always low when she's on chemo. In fact, yesterday it was 2.0 because she stopped her potassium pills for a few days. So she's going in for IV doses today. The docs have never had a good answer for why the chemo affects her potasium this way--it just does. The pills irritate her stomach, too, which has been hard on top of the xeloda/tykerb.
