Precautions While Using This Medicine
It is very important that your doctor check your progress while you are using panobinostat to see if it is working properly and to check for unwanted effects. Blood tests may be needed to check for unwanted effects.
Using panobinostat while you are pregnant can harm your unborn baby. Use an effective form of birth control (eg, condoms) to keep from getting pregnant during therapy and for 1 month after the last dose (for sexually-active females), and for 3 months after the last dose (for sexually-active men). If you think you or your partner have become pregnant while using the medicine, tell your doctor right away.
Cancer medicines can cause diarrhea, nausea, or vomiting in most people, sometimes even after receiving medicines to prevent it. Ask your doctor or nurse about other ways to control these side effects.
Contact your doctor right away if you have any changes to your heart rhythm. You might feel dizzy or faint, or you might have a fast, pounding, or uneven heartbeat. Make sure your doctor knows if you or anyone in your family has ever had a heart rhythm problem such as QT prolongation.
Panobinostat can temporarily lower the number of white blood cells in your blood, increasing the chance of getting an infection. It can also lower the number of platelets, which are necessary for proper blood clotting. If this occurs, there are certain precautions you can take, especially when your blood count is low, to reduce the risk of infection or bleeding:
- If you can, avoid people with infections. Check with your doctor immediately if you think you are getting an infection or if you get a fever or chills, cough or hoarseness, lower back or side pain, or painful or difficult urination.
- Check with your doctor immediately if you notice any unusual bleeding or bruising, black, tarry stools, blood in the urine or stools, or pinpoint red spots on your skin.
- Be careful when using a regular toothbrush, dental floss, or toothpick. Your medical doctor, dentist, or nurse may recommend other ways to clean your teeth and gums. Check with your medical doctor before having any dental work done.
- Do not touch your eyes or the inside of your nose unless you have just washed your hands and have not touched anything else in the meantime.
- Be careful not to cut yourself when you are using sharp objects such as a safety razor or fingernail or toenail cutters.
- Avoid contact sports or other situations where bruising or injury could occur.
Panobinostat may increase your risk of developing infections. Avoid being near people who are sick or have infections while you are using panobinostat. Wash your hands often. Tell your doctor if you have any kind of infection before you start using panobinostat. Also tell your doctor if you have ever had an infection that would not go away or an infection that kept coming back.
Check with your doctor right away if you have pain or tenderness in the upper stomach, pale stools, dark urine, loss of appetite, nausea, vomiting, or yellow eyes or skin. These could be symptoms of a serious liver problem.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
