What is romidepsin?

Romidepsin blocks certain enzymes in the body and interferes with the growth of tumor cells.

Romidepsin is used to treat T-cell lymphoma affecting the skin (cutaneous T-cell lymphoma, or CTCL).

Romidepsin is usually given after other medications have been tried without successful treatment of symptoms.

Romidepsin may also be used for other purposes not listed in this medication guide.

What is the most important information I should know about romidepsin?

Before you receive romidepsin, tell your doctor if you have an electrolyte imbalance, a personal or family history of "Long QT syndrome," heart disease, kidney disease, or liver disease.

Do not receive romidepsin if you are pregnant. It could harm the unborn baby. Use effective birth control, and tell your doctor if you become pregnant during treatment. Hormonal forms of contraception (such as birth control pills, injections, implants, skin patches, and vaginal rings) may not be effective enough to prevent pregnancy during your treatment. Ask your doctor about using a non-hormone method of birth control (such as a condom, diaphragm, spermicide) to prevent pregnancy while taking romidepsin. You will need regular medical tests to be sure this medication is not causing harmful effects. Do not miss any follow-up visits to your doctor.

Call your doctor if you have a serious side effect such as severe nausea or vomiting, chest pain, fast or uneven heartbeats, feeling short of breath, fever, chills, flu symptoms, pale skin, easy bruising or bleeding, muscle cramps, confusion, pain or burning when you urinate, or worsening of your CTCL skin symptoms.

What should I discuss with my health care provider before receiving romidepsin?

You should not use this medication if you are allergic to it.

If you have any of these other conditions, you may need a dose adjustment or special tests to safely receive this medication:

  • an electrolyte imbalance (such as high or low levels of potassium or magnesium in your blood);

  • a personal or family history of "Long QT syndrome";

  • heart disease;

  • kidney disease; or
  • liver disease.
FDA pregnancy category D. Romidepsin can cause harm to an unborn baby or cause birth defects. Before you receive romidepsin, tell your doctor if you are pregnant. Use an effective form of birth control, and tell your doctor if you become pregnant during treatment. Hormonal forms of contraception (such as birth control pills, injections, implants, skin patches, and vaginal rings) may not be effective enough to prevent pregnancy during your treatment. Ask your doctor about using a non-hormone method of birth control (such as a condom, diaphragm, spermicide) to prevent pregnancy while taking romidepsin.

How is romidepsin given?

Romidepsin is given as an injection through a needle placed into a vein. You will receive this injection in a clinic or hospital setting. The medicine must be given slowly through an IV infusion, and can take up to 4 hours to complete.

Romidepsin is usually given every 7 days for 3 weeks. This treatment cycle may be repeated 28 days after your first dose. Your doctor will determine how long to treat you with romidepsin.

Romidepsin can lower the blood cells that help your body fight infections. This can make it easier for you to bleed from an injury or get sick from being around others who are ill.

To be sure your blood cells do not get too low, your blood will need to be tested on a regular basis. Your heart rate may need to be checked using an electrocardiograph or ECG (sometimes called an EKG). Your cancer treatments may be delayed based on the results of these tests. Do not miss any scheduled visits to your doctor.

What happens if I miss a dose?

Call your doctor for instructions if you miss an appointment for your romidepsin injection.

What happens if I overdose?

Seek emergency medical attention if you think you have used too much of this medicine.

Symptoms of a romidepsin overdose are not known.
