Veltassa is indicated for the treatment of hyperkalemia in adults and pediatric patients ages 12 years and older. Limitation of Use: Veltassa should not be used as an emergency treatment for life-threatening hyperkalemia because of its delayed onset of action [see Clinical Pharmacology (1.

Amiloride HCl is indicated as adjunctive treatment with thiazide diuretics or other kaliureticdiuretic agents in congestive heart failure or hypertension to: help restore normal serum potassium levels in patients who develop hypokalemia on the kaliuretic diuretic. prevent development of hypokalemia in patients who would be exposed to particular risk if hypokalemia were to develop, e.g., digitalized patients or patients with significant cardiac arrhythmias. The use of potassium-conserving agents is often unnecessary in patients receiving diuretics for uncomplicated essential hypertension when such patients have a normal diet. Amiloride HCl has little additive diuretic or antihypertensive effect when added to a thiazide diuretic. Amiloride HCl should rarely be used alone. It has weak (compared with thiazides) diuretic and antihypertensive effects. Used as single agents, potassium sparing diuretics, including amiloride HCl, result in an increased risk of hyperkalemia (approximately 10% with amiloride). Amiloride HCl should be used alone only when persistent hypokalemia has been documented and only with careful titration of the dose and close monitoring of serum electrolytes.
