How can i safely use a fleet enema for constipation if i have chronically low potassium?

See below. : Good question. Fleets enema: commonly used ~4 oz saline laxative; sodium phosphate-based; can cause adverse reactions in certain individuals (age >55) with certain pre-existing conditions (e.g. dehydration, impaired kidney function, congestive heart failure, abnormal electrolytes) if used too often (>3 days or >1 dose/24 hrs). I recommend you ask your MD about proper dosing and alternatives.
