Potassium-sparing diuretics reduce potassium excretion. Potassium supplements add to this effect.
📋 Effect
Hyperkalemia; cardiac arrhythmia risk
💊 Management
Avoid potassium supplements. Monitor serum potassium closely.
Plain Language Summary
This combination is dangerous. Taking potassium supplements while using these diuretics can cause your potassium levels to become dangerously high, which may lead to serious heart rhythm problems.
