Unlike loop/thiazide diuretics, potassium-sparing diuretics RETAIN potassium and magnesium. This means supplementing potassium or magnesium while on these drugs can cause dangerously high levels (hyperkalemia, hypermagnesemia). This is the opposite pattern from most diuretics.
Standard pharmacology — class effect of aldosterone antagonism on electrolyte retention
If supplementing K+ or Mg2+: dangerous cardiac arrhythmia risk from electrolyte excess
CAUTION: Do NOT supplement potassium or magnesium without physician approval and electrolyte monitoring. The standard EBL recommendation to supplement magnesium with diuretics does NOT apply to this drug class.

Spironolactone is an anti-androgen — it blocks androgen receptors and increases androgen-binding globulin. This indirectly reduces zinc status since testosterone-mediated zinc uptake is reduced.
Liao et al. — spironolactone's anti-androgenic effects reduce zinc-testosterone signaling
Reduced libido, fatigue, immune effects, delayed wound healing
