Velbastine is a chemotherapy drug used to treat certain types of tumors, such as lymphoma and testicular cancer. It works by preventing cancer cells from dividing by affecting the microtubules within the cell, which are responsible for regulating the process of division. This drug is given intravenously and requires close medical monitoring due to its side effects, which may include low blood cells, constipation, hair loss, and weakness in the extremities. Neurological symptoms should be monitored regularly, and blood tests should be performed throughout the treatment period. Velbastine should not be used during pregnancy or breastfeeding, and the doctor should be informed about all other medications being taken to avoid serious interactions and complications.
