6 ADVERSE REACTIONS The most frequently reported adverse reactions ( > 5%) after administration of VALSTAR are urinary frequency, dysuria, urinary urgency, bladder spasm, hematuria, bladder pain, urinary incontinence, cystitis, urinary tract infection, nocturia, local burning symptoms, abdominal pain, and nausea. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Endo at 1-800-462-3636 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 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.

8.1 Pregnancy Risk Summary Based on findings in animal studies and its mechanism of action, VALSTAR can cause fetal harm when administered to a pregnant females [see Clinical Pharmacology ( 12.1 and 12.3 )] . There are no available data in pregnant females to inform the drug-associated risk. In animal reproduction studies, intravenous administration of valrubicin to pregnant rats during the period of organogenesis at a dose about 0.2 times the recommended human intravesical dose caused embryo-fetal malformations and increased resorptions [see Data] .

5 WARNINGS AND PRECAUTIONS Delaying cystectomy can lead to development of metastatic bladder cancer, which is lethal. ( 5.1 ) Do not administer VALSTAR to patients with a perforated bladder or to those in whom the integrity of the bladder mucosa has been compromised. ( 5.2 , 12.3 ) Evaluate the status of the bladder before the intravesical instillation of VALSTAR. ( 5.3 ) Use with caution in patients with severe irritable bladder symptoms. ( 5.4 ) Embryo-Fetal Toxicity: VALSTAR can cause fetal harm. Advise females of reproductive potential of the potential risk to a fetus and to use effective contraception. 4 CONTRAINDICATIONS VALSTAR is contraindicated in patients with: Perforated bladder [ see Warnings and Precautions ( 5.2 )] Known hypersensitivity to anthracyclines or polyoxyl castor oil Active urinary tract infection Small bladder capacity and unable to tolerate a 75 mL instillation Perforated bladder or compromised bladder mucosa ( 4 , 5.2 ) Hypersensitivity to anthracyclines or polyoxyl castor...
