Potassium Supplements: Who Should Avoid or Use Cautiously

Potassium supplements require caution or avoidance in:

1. Hyperkalemia: Already high potassium → risk of muscle weakness, arrhythmia, paralysis.
2. Kidney Disease/CKD: Impaired excretion → hyperkalemia risk.
3. Certain Heart Conditions: Heart failure, arrhythmias—high potassium worsens these.
4. Digestive Issues: Obstruction, ulcers, diverticular disease—potassium may irritate.
5. Medication Interactions: ACE inhibitors, ARBs, diuretics, potassium-sparing drugs—consult doctor/pharmacist.
6. Addison's Disease: Adrenal insufficiency affects potassium regulation.
7. Pregnancy/Breastfeeding: Dose/safety varies—consult provider.
