Other warnings you should know about:

IDAMYCIN PFS can cause serious side effects including:

• Hyperuricemia (high uric acid levels in the blood): Treatment with idarubicin can result in a large number of cancer cells dying and releasing their contents into the blood (also known as tumour lysis syndrome). This can lead to hyperuricemia. Your healthcare professional will monitor the profile of your blood (e.g., levels of uric acid, potassium, calcium, phosphate, and creatinine) before your treatment. They will suggest ways to prevent hyperuricemia (e.g., by staying hydrated ), which may also help minimize the effects of tumour lysis syndrome.

• Injury around the site of injection: Extravasation (leakage of the injected solution that causes damage around the site of injection) can occur when IDAMYCIN PFS is given to you. This can lead to local pain, severe tissue lesions (e.g., a lump, bump, sore, or patch), severe local tissue necrosis (tissue death), and phlebosclerosis (a diseases

  • . If you develop extravasation, your healthcare professional will stop your treatment right away.
• Blood clots: The use of cytotoxic agents, such as idarubicin, has been reported to cause blood clots and thrombophlebitis (inflammation caused by blood clots, usually in the leg). Your healthcare professional will monitor your health for signs and symptoms of blood clots.
• Secondary leukemia (a type of cancer that develops from previous disorders or exposure to cytotoxic agents): Treatment with anthracyclines (cytotoxic agents), such as IDAMYCIN PFS, can lead to secondary leukemia. Your healthcare professional will monitor you for signs and symptoms of secondary leukemia.

• Gastrointestinal problems: Treatment with IDAMYCIN PFS can cause gastrointestinal problems including:

  • mucositis (inflammation and ulceration of the mucous membranes lining the digestive tract),
  • gastrointestinal perforation (a hole in the wall of your stomach or bowels), and
  • gastrointestinal bleeding (bleeding anywhere along the GI tract between mouth and anus).

Your healthcare professional will monitor and assess your health before and during your treatment with IDAMYCIN PFS.

• Kidney problems: Treatment with IDAMYCIN PFS can cause kidney problems. You will have regular tests done before and during your treatment with IDAMYCIN PFS. These tests will tell your healthcare professional how your kidney is working.

Fertility:

• IDAMYCIN PFS is a cytotoxic agent and can cause fertility impairment. If you are a male, it can damage the DNA in your sperm. You and your partner should use effective birth control while taking IDAMYCIN PFS and for at least 3.5 months after your last dose.
• If you want to become pregnant or father a child after treatment with IDAMYCIN PFS, talk to your healthcare professional about fertility preservation options before starting your treatment.

Check-ups and testing:

You will have regular visits with your healthcare professional before, during, and after your treatment. They may do tests that will assess the profile of your blood, and how your heart, liver, and kidneys are working. This will help your healthcare professional assess your health and tell them how IDAMYCIN PFS is affecting you.

Tell your healthcare professional about all the medicines you take, including any drugs, vitamins, minerals, natural supplements or alternative medicines.

• chemotherapy medicines used to treat different types of cancers such as:

  • anthracyclines

  • cardiotoxic drugs (e.g., cyclophosphamide and paclitaxel)
  • cardioactive compounds (e.g., amlodipine, diltiazem, and verapamil)
• medicines known as corticosteroids that are used to reduce inflammation and suppress the immune system (e.g., dexamethasone).
