Vorinostat is used to treat cutaneous T-cell lymphoma (CTCL, a type of cancer) in people whose disease has not improved, has gotten worse, or has come back after taking other medications. Vorinostat is in a class of medications called histone deacetylase (HDAC) inhibitors. It works by killing or stopping the growth of cancer cells.
Vorinostat comes as a capsule to take by mouth. It is usually taken once a day with food. Your doctor will tell you whether to take vorinostat every day or only on certain days of the week. Take vorinostat at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take vorinostat exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow the capsules whole; do not open, chew, or crush them. If you are not able to swallow the capsules whole, call your doctor. If vorinostat capsules are accidentally opened or crushed, do not touch the capsules or the powder. If the powder from an open or crushed capsule gets on your skin or in your eyes or nose, wash the area well with plenty of water and call your doctor.
