Summary
Dichlorphenamide commonly causes hypokalemia and metabolic acidosis. Sorafenib can cause QT prolongation and electrolyte disturbances, so low potassium may increase arrhythmia risk.
What this interaction means in plain words
Dichlorphenamide and Sorafenib can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Dichlorphenamide belongs to Miscellaneous; Sorafenib belongs to Oncology.
Why it happens
Dichlorphenamide causes renal potassium loss via carbonic anhydrase inhibition, which adds to the QT-prolonging potential of sorafenib.
What to do
Monitor serum potassium, bicarbonate and magnesium regularly, and replace potassium as needed. Obtain an ECG if other QT risk factors are present.
