Summary
Hydroxyurea suppresses bone marrow and immune function. Intravesical live BCG in an immunosuppressed patient raises the risk of systemic BCG infection and may reduce antitumor effect.
What this interaction means in plain words
Bcg intravesical live and Hydroxyurea can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Why it happens
Immunosuppression impairs control of live BCG organisms and the immune response.
What to do
Avoid intravesical BCG during hydroxyurea therapy. Consider an alternative bladder cancer therapy or delay BCG until immune function has recovered.
