Spironolactone Takeda is used for various forms of morbid fluid accumulation ( edema ) and high blood pressure when other treatment has no effect or is insufficient. It is also used for increased production of the adrenal cortex hormone aldosterone (primary aldosteronism) where another therapy is insufficient or inappropriate.

Children should only be treated by a pediatrician.
