Valstar (valrubicin) Disease Interactions

There are 2 disease interactions with Valstar (valrubicin):


Valrubicin (Includes Valstar) ↔ Perforated Bladder

Severe Potential Hazard, Moderate plausibility

Applies to: Rupture of Bladder

Valrubicin is contraindicated in patients with perforated bladder or compromised bladder mucosa, including small bladder capacity that is unable to tolerate a 75 mL instillation. Evaluate the bladder before the intravesical instillation for severe irritable bladder symptoms, and in case of bladder perforation, delay the administration until bladder integrity has been restored. If this agent is administered to patients with bladder rupture or if perforation is suspected, significant systemic exposure may occur following intravesical administration and myelosuppression is possible. Weekly monitoring of complete blood counts should be performed for 3 weeks.


Valrubicin (Includes Valstar) ↔ Urinary Infection

Severe Potential Hazard, Moderate plausibility

Applies to: Urinary Tract Infection

Valrubicin is contraindicated in patients with current urinary tract infection.
