Summary
Dichlorphenamide, a carbonic anhydrase inhibitor, increases urinary potassium loss and can cause hypokalemia and metabolic acidosis. Insulin also shifts potassium into cells, so combined use can deepen hypokalemia.
What this interaction means in plain words
Dichlorphenamide and Insulin aspart 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; Insulin aspart belongs to Endocrine.
Why it happens
Additive hypokalemia from renal potassium wasting (carbonic anhydrase inhibition) and insulin-mediated intracellular potassium shift.
What to do
Check serum potassium and bicarbonate at baseline and periodically during combined use. Supplement potassium if needed and adjust therapy accordingly.
