Descriptions


Romidepsin injection is used to treat certain types of cancer of the white blood cells called cutaneous T-cell lymphoma (CTCL) and peripheral T-cell lymphoma (PTCL). This medicine is used in patients who have already been treated with at least 1 previous treatment.

Romidepsin interferes with the growth of cancer cells, which are eventually destroyed by the body. Since the growth of normal body cells may also be affected, other unwanted effects will also occur. Some of these may be serious and must be reported to your doctor. Before you begin treatment with romidepsin, you and your doctor should talk about the benefits of this medicine as well as the risks of receiving it.

This medicine is to be given only by or under the direct supervision of a doctor.

This product is available in the following dosage forms:

Romidepsin 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.

You may get infections more easily while using this medicine. These can occur during treatment and within 30 days after the last dose. Tell your doctor right away if you have a fever, cough, burning sensation on urination, flu-like symptoms, muscle aches, or worsening skin problems.

This medicine may cause heart rhythm changes, such as a condition called QT prolongation. It may change the way your heart beats and cause fainting or serious side effects. Contact your doctor right away if you have a fast, pounding, or uneven heartbeat, chest pain, or troubled breathing.

This medicine may cause a serious type of reaction called tumor lysis syndrome. Your doctor may give you a medicine to help prevent this. Call your doctor right away if you have a decrease or change in urine amount, joint pain, stiffness, or swelling, lower back, side, or stomach pain, rapid weight gain, swelling of the feet or lower legs, or unusual tiredness or weakness.

If you plan to have children, talk with your doctor before receiving this medicine. Some men and women receiving this medicine have become infertile (unable to have children).

Cancer medicines can cause nausea or vomiting even after receiving medicines to prevent it. Ask your doctor or nurse about other ways to control these side effects.
