romidepsin intravenous

COMMON BRAND NAME(S): Istodax

GENERIC NAME(S): ROMIDEPSIN

Uses

Romidepsin is used to treat a certain type of cancer (CTCL-cutaneous T-cell lymphoma). Romidepsin works by stopping the growth of cancer cells.

How to use romidepsin intravenous

Read the Patient Information Leaflet if available from your pharmacist before your first romidepsin treatment and each time you get another dose. If you have any questions regarding the information, ask your doctor or pharmacist.

This medication is mixed in a solution and given slowly into a vein over 4 hours by a health care professional as directed by your doctor. It is usually given on day 1, day 8, and day 15, every 28 days.

The dosage is based on your medical condition, body size, and response to treatment. Before each cycle, you should have blood tests to find the best dose for you and to see whether you need to wait before receiving this drug again.

Side Effects

Nausea, vomiting, tiredness, and loss of appetite may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.

Many people using this medication have serious side effects. However, your doctor has prescribed this drug because he or she has judged that the benefit to you is greater than the risk of side effects. Careful monitoring by your doctor may decrease your risk.

This medication decreases bone marrow function, an effect that may lead to a low number of blood cells such as red cells, white cells, and platelets. This can cause anemia, decrease your body's ability to fight an infection, or cause easy bruising/bleeding. Your doctor will order blood tests to check for this side effect. It is important to keep all medical/lab test appointments. Tell your doctor immediately if you develop any of the following symptoms: easy bruising/bleeding, pale skin, unusual tiredness, signs of infection (such as fever, chills, cough, persistent sore throat, painful/burning urination).

Seek immediate medical attention if any of these unlikely but serious side effects occur: chest pain, fast/irregular heartbeat, severe dizziness, fainting.

A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.

This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

Precautions

Before receiving this medication, tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.

Before using this medication, tell your doctor or pharmacist your medical history, especially of: liver disease (such as hepatitis B), heart disease (such as chest pain, heart attack).

This drug may cause tiredness. Do not drive, use machinery, or do any activity that requires alertness until you are sure you can perform such activities safely. Limit alcoholic beverages.

Romidepsin may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can infrequently result in serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need medical attention right away.

The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may cause QT prolongation. Before using romidepsin, tell your doctor or pharmacist of all the drugs you take and if you have any of the following conditions: certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG), family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death).

Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/"water pills") or if you have conditions such as severe sweating, diarrhea, or vomiting. Talk to your doctor about using romidepsin safely.

Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).

Romidepsin can make you more likely to get infections or may worsen any current infections. Therefore, wash your hands well to prevent the spread of infection. Avoid contact with people who have infections that may spread to others (such as chickenpox, measles, flu). Consult your doctor if you have been exposed to an infection or for more details.

Do not have immunizations/vaccinations without the consent of your doctor. Avoid contact with people who have recently received live vaccines (such as flu vaccine inhaled through the nose).

To lower the chance of getting cut, bruised, or injured, use caution with sharp objects like razors and nail cutters, and avoid activities such as contact sports.

Older adults may be more sensitive to the side effects of this drug, especially QT prolongation (see above).

This medication is not recommended for use during pregnancy. It may harm an unborn baby. Consult your doctor for more details. See also Drug Interactions section.

It is unknown if this drug passes into breast milk and may harm nursing infants. Breast-feeding while using this drug is not recommended. Consult your doctor before breast-feeding.

Interactions

See also Precautions section.

The effects of some drugs can change if you take other drugs or herbal products at the same time. This can increase your risk for serious side effects or may cause your medications not to work correctly. These drug interactions are possible, but do not always occur. Your doctor or pharmacist can often prevent or manage interactions by changing how you use your medications or by close monitoring.

To help your doctor and pharmacist give you the best care, be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products) before starting treatment with this product. While using this product, do not start, stop, or change the dosage of any other medicines you are using without your doctor's approval.

Some products that may interact with this drug include: disulfiram, "blood thinners" (such as warfarin).

Other medications can affect the removal of romidepsin from your body, thereby affecting how romidepsin works. These drugs include azole antifungals (such as itraconazole, ketoconazole), dexamethasone, macrolide antibiotics (such as clarithromycin), HIV drugs (such as ritonavir), nefazodone, rifamycins (such as rifabutin, rifampin), St. John's wort, and some drugs used to treat seizures (such as carbamazepine), among others.

This medication may decrease the effectiveness of hormonal birth control such as pills, patch, or ring. This could cause pregnancy. Discuss with your doctor or pharmacist if you should use additional reliable birth control methods while using this medication. Also tell your doctor if you have any new spotting or breakthrough bleeding, because these may be signs that your birth control is not working well.

Many drugs besides romidepsin may affect the heart rhythm (QT prolongation), including amiodarone, dofetilide, pimozide, procainamide, quinidine, sotalol, macrolide antibiotics (such as erythromycin), among others.
