What is valrubicin?

Valrubicin is used to treat bladder cancer that has not spread to other parts of the body.

Most people do not have a complete response to valrubicin. You may eventually need surgery to remove your bladder to prevent the cancer from becoming metastatic (spreading to other parts of your body).

Valrubicin may also be used for purposes not listed in this medicine guide.

How is valrubicin given?

Valrubicin is injected directly into the bladder using a catheter that is inserted into the urethra (the tube that carries urine out of your bladder). A healthcare provider will give you this medicine, usually once a week for 6 weeks.

Valrubicin is typically given in a solution that amounts to about 2.5 ounces (1/3 cup). This entire amount is injected into the bladder and should be held in for 2 hours. Do not use the bathroom during this time.

Tell your doctor if you have trouble holding in the medicine for the full 2 hours.

If this medicine accidentally gets on your skin, wash it thoroughly with soap and warm water.

You will need frequent urine tests, and you may also need a bladder biopsy or a bladder exam using a scope.

Drink plenty of water after each time you receive valrubicin.

You may not have a complete response to valrubicin. After 3 months of treatment without response, your bladder may need to be surgically removed. This can help prevent your cancer from spreading to other parts of your body. Metastatic bladder cancer is usually fatal.

Before taking this medicine

You should not be treated with valrubicin if you are allergic to it, or if you have:

  • a urinary tract infection;

Tell your doctor if you have ever had:

  • overactive bladder, incontinence or leakage;
  • bladder surgery; or
  • trouble holding a large amount of urine in your bladder.

It may be harder for you to get a woman pregnant while you are using valrubicin. You should still use birth control to prevent pregnancy because the medicine can harm an unborn baby.

Valrubicin can harm an unborn baby if the mother or the father is using this medicine.

What happens if I overdose?

Since valrubicin is given by a healthcare professional in a medical setting, an overdose is unlikely but may cause worsening bladder symptoms.

Follow your doctor's instructions about any restrictions on food, beverages, or activity.

What other drugs will affect valrubicin?

Because valrubicin does not get into the bloodstream, it is unlikely to be influenced by other medications you take. However, many drugs can interact with one another. Inform all your healthcare providers about all the medicines you use, including prescription and over-the-counter medicines, vitamins, and herbal products.
