Rituximab
"I had three treatments of Bendamustine and rituximab for indolent follicular lymphoma. It seemed to work well on the lymphoma,  which has not completely gone, but after the third treatment I developed shortness of breath. It took doctors a month to diagnose it as rituximab induced lung disease (bronchiolitis oblivitans). I am now  permanently and severely disabled, unable to walk more than 10 feet, extreme difficulty in caring for myself. I am 55 with no other medical conditions, three months ago I could run, ski, and enjoy life. This drug destroyed the quality of my life and created complications for fighting lymphoma. The doctors said it was safe. I was not told about the serious and potentially fatal side effects."
