Summary
Both SSRIs and loop diuretics can lower serum sodium, so combining them may increase the risk of hyponatremia, particularly in older adults. Symptoms range from mild confusion and fatigue to seizures in severe cases.
What this interaction means in plain words
Ethacrynic acid and Paroxetine 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.

Why it happens
Additive pharmacodynamic effects: SSRI-associated inappropriate ADH secretion plus diuretic-induced renal sodium loss.
