Valstar (valrubicin) is a cancer (antineoplastic) medication used to treat bladder cancer. Common side effects of Valstar include bladder irritation (symptoms such as pain, spasm, frequent urge to urinate, and blood in the urine), urinary incontinence, urinary tract infection, and nausea. Valstar usually will cause urine to turn a reddish color for about 24 hours following a dose. This is a normal, harmless side effect of Valstar and should not be mistaken for blood in the urine.

Valstar is recommended at a dose of 800 mg administered intravesically (instilled into the bladder) once a week for six weeks. Valstar may interact with "live" vaccines. Tell your doctor all medications and supplements you use. Valstar is not recommended for use during pregnancy. It may harm a fetus. If you become pregnant or think you may be pregnant, tell your doctor. Both males and females using this drug should use birth control (e.g., birth control pills, condoms) during treatment. Consult your doctor to discuss birth control. It is unknown if this drug passes into breast milk. Because of the possible risk to the infant, breastfeeding while using this drug is not recommended.

Our Valstar (valrubicin) Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication.

SIDE EFFECTS

Clinical Trial Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The safety of VALSTAR was assessed in 230 patients with transitional cell carcinoma of the bladder, including 205 patients who received multiple weekly doses. One hundred seventy-nine of the 205 patients received the approved dose and schedule of 800 mg weekly for multiple weeks.

Approximately 84% of patients who received intravesical VALSTAR in clinical studies experienced local adverse reactions. The local adverse reactions associated with VALSTAR usually occur during or shortly after instillation and resolve within 1 to 7 days after the instillate is removed from the bladder. Seven out of 143 patients (5%) who were scheduled to receive six doses of VALSTAR failed to receive all of the planned doses because of the occurrence of local bladder symptoms.

TABLE 1 displays the frequency of the local adverse reactions at baseline and during treatment among 179 patients who received 800 mg doses of VALSTAR in a multiple-cycle treatment regimen.
