@CyborGhost: This article should mention that spironolactone is a potassium-sparing diuretic (maybe in a side-effects section), in other words, you need to watch out for dehydration and avoid consuming high amounts of potassium. Kaldari (talk) 06:20, 20 March 2018 (UTC)

And as long as you're adding side effects, you might want to also mention that it lowers blood pressure (which can be a good thing unless you already have low blood pressure, in which case it can cause dizziness or fainting). Kaldari (talk) 06:23, 20 March 2018 (UTC)
