Laxative Risks
Saline laxatives can produce significant reductions in body
fluids and cause electrolyte imbalances
Patients may experience adverse effects associated with dehydration
and electrolyte imbalances
Elderly patients, patients with impaired renal function or congestive
heart failure (CHF), and patients on sodium-restricted or fluid-restricted
diets are at greater risk of dehydration and electrolyte imbalances
associated with saline laxatives
