What is Zolinza?

Zolinza is usually given after other treatments did not work or have stopped working, or your cutaneous T-cell lymphoma gets worse or comes back after you have taken other medicines.

It is not known if Zolinza is safe and effective in children.


You should not use Zolinza if you are allergic to vorinostat, or if you have severe liver disease.
