Swelling feet &legs

Has anyone else suffered from their legs and feet swelling to 3x their normal size? I know about pitting edema (which this is) but this is all over her body. Her stomach is also painfully distended like she's 5 months pregnant. They've got her on Lasix but it doesn't look like it is working. Any ideas or suggestions for something else that would help reduce the swelling? They say it's colitis caused by a cancer med called Capecitabine.
