Panobinostat comes as a capsule to take by mouth. It is usually taken with or without food once daily on certain days of a 21-day cycle. The cycle may be repeated for up to 16 cycles. Take panobinostat at around the same time on each scheduled day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take panobinostat 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 with a glass of water; do not crush, chew, or open them. Handle the capsules as little as possible. If you touch a broken panobinostat capsule or the medicine in the capsule, wash that area of your body with soap and water. If the medicine in the capsule gets into your mouth, nose, or eyes, wash it away with plenty of water.
If you vomit after taking panobinostat, do not take another dose. Continue your regular dosing schedule.
Be sure to tell your doctor how you are feeling during your treatment. Your doctor may decrease your dose of panobinostat or stop your treatment for a while or permanently if you experience side effects of the medication.
