shortness of breath with Tykerb

[pamuk]

Has anyone else experienced a shortness of breath, kind of a wheeziness, from Tykerb? My sister started on Tykerb a few weeks ago. She is having a tough time with the side effects (nausea and diarrhea are pretty bad) but now also has a shortness of breath that came on fairly suddenly and improves when she stops taking Tykerb (her onc has taken her off for a week because she was getting so weak). I just wondered if this has happened to anyone else.
