⚠️ Mechanism
ACE inhibitors reduce aldosterone, decreasing potassium excretion. Potassium supplements add to this effect.
📋 Effect
Hyperkalemia (dangerously high potassium); cardiac arrhythmia risk
💊 Management
Avoid potassium supplements with ACE inhibitors/ARBs. Monitor serum potassium.
Plain Language Summary
This combination is dangerous because ACE inhibitors can cause your body to hold onto more potassium. Taking potassium supplements while on this medication can lead to dangerously high potassium levels, which may cause irregular heartbeats.
