title: Digoxin-rifampin interaction.
abstract: Digoxin doses required to maintain therapeutic serum concentrations rose substantially in two patients dependent on dialysis with the commencement of rifampin therapy. When rifampin was discontinued, doses fell to requirements before rifampin. Serum digoxin concentration may fall to ineffective levels with rifampin therapy and rise to potentially toxic levels when rifampin is discontinued.
