D
Sulfonamides interact with several drugs and through metabolism-related interactions can inten-sify the effects of warfarin. Patients taking both should be monitored closely for bleeding ten-dencies. Changing to the combination product will not help, because sulfonamides are still present. Sulfonamides intensify glipizide levels, so this drug may actually need to be reduced. Trimethoprim, not sulfonamides, raises potassium levels.
