Closely monitor digoxin levels if used concomitantly ( 5.7 ).

If digoxin is used to prevent a rapid ventricular response, serum digoxin levels should be closely monitored, because digoxin levels may be increased with use of quinine [see DRUG INTERACTIONS ( 7.2 )] .

Digoxin Increased digoxin plasma concentration ( 5.8 , 7.1 ).

Digoxin (P-gp Substrate) In 4 healthy subjects who received digoxin (0.5 to 0.75 mg/day) during treatment with quinine (750 mg/day), a 33% increase in mean steady state AUC of digoxin and a 35% reduction in the steady state biliary clearance of digoxin were observed compared to digoxin alone.

Thus, if quinine sulfate is administered to patients receiving digoxin, plasma digoxin concentrations should be closely monitored, and the digoxin dose adjusted, as necessary [see WARNINGS AND PRECAUTIONS ( 5.7 )] .
