Hepatic to bicarbonate
Use: Labeled Indications
Kidney stones: For the management of renal tubular acidosis with calcium stones, hypocitraturic calcium oxalate nephrolithiasis of any etiology, and uric acid lithiasis with or without calcium stones.
Renal insufficiency (GFR <0.7 mL/kg/minute); patients with hyperkalemia or with conditions predisposing to hyperkalemia (eg, chronic renal failure, acute dehydration, adrenal insufficiency, uncontrolled diabetes mellitus, tissue breakdown, strenuous physical exercise in unconditioned individuals); patients with delayed gastric emptying, esophageal compression, or intestinal obstruction or stricture; patients with active urinary tract infection; peptic ulcer disease
Alkalinizer, bicarbonate precursor: Oral:
Mild to moderate hypocitraturia (>150 mg/day urinary citrate): Initial: 15 mEq 2 times daily or 10 mEq 3 times daily; maximum dose: 100 mEq/day
Severe hypocitraturia (<150 mg/day urinary citrate): Initial: 30 mEq 2 times daily or 20 mEq 3 times daily; maximum dose: 100 mEq/day
Refer to adult dosing.
Administer with meals or bedtime snack (or within 30 minutes after). Swallow tablets whole with a full glass of water.
Bariatric surgery: Tablet, extended release: Some institutions may have specific protocols that conflict with these recommendations; refer to institutional protocols as appropriate. ER tablet should be swallowed whole. Do not crush, chew, or suck on tablet. Take when upright or in sitting position. No alternative formulations are available for citrate formulation. Potassium is a known GI irritant. Minimum necessary dose and duration of potassium therapy is recommended to minimize risk of GI irritation or ulceration. Proton pump inhibitor therapy is recommended if therapy is to continue chronically.
Ensure adequate fluid intake; limit salt intake. Take with meals or snack.
Store at controlled room temperature.
Aliskiren: Potassium Salts may enhance the hyperkalemic effect of Aliskiren. Monitor therapy
Alpha-/Beta-Agonists (Indirect-Acting): Alkalinizing Agents may increase the serum concentration of Alpha-/Beta-Agonists (Indirect-Acting). Monitor therapy
Aluminum Hydroxide: Citric Acid Derivatives may increase the absorption of Aluminum Hydroxide. Monitor therapy
Amantadine: Alkalinizing Agents may increase the serum concentration of Amantadine. Monitor therapy
Amphetamines: Alkalinizing Agents may decrease the excretion of Amphetamines. Management: Consider alternatives to using amphetamines and alkalinizing agents in combination. If these agents must be used together, patients should be monitored closely for excessive amphetamine effects. Consider therapy modification
Angiotensin II Receptor Blockers: Potassium Salts may enhance the hyperkalemic effect of Angiotensin II Receptor Blockers. Monitor therapy
Angiotensin-Converting Enzyme Inhibitors: Potassium Salts may enhance the hyperkalemic effect of Angiotensin-Converting Enzyme Inhibitors. Monitor therapy
Anticholinergic Agents: May enhance the ulcerogenic effect of Potassium Citrate. Avoid combination
Drospirenone: Potassium Salts may enhance the hyperkalemic effect of Drospirenone. Monitor therapy
Eplerenone: May enhance the hyperkalemic effect of Potassium Salts. Management: This combination is contraindicated in patients receiving eplerenone for treatment of hypertension. Consider therapy modification
Heparin: May enhance the hyperkalemic effect of Potassium Salts. Monitor therapy
Heparins (Low Molecular Weight): May enhance the hyperkalemic effect of Potassium Salts. Monitor therapy
Mecamylamine: Alkalinizing Agents may increase the serum concentration of Mecamylamine. Monitor therapy
Memantine: Alkalinizing Agents may increase the serum concentration of Memantine. Monitor therapy
Nicorandil: May enhance the hyperkalemic effect of Potassium Salts. Monitor therapy
Potassium-Sparing Diuretics: Potassium Salts may enhance the hyperkalemic effect of Potassium-Sparing Diuretics. Management: Avoid coadministration of a potassium-sparing diuretic and a potassium salt. This combination should only be used in cases of significant hypokalemia, and only if serum potassium can be closely monitored. Consider therapy modification
QuiNINE: Alkalinizing Agents may increase the serum concentration of QuiNINE. Monitor therapy
Frequency not defined.
Endocrine & metabolic: Hyperkalemia
Gastrointestinal: Abdominal distress, diarrhea, nausea, vomiting
Concerns related to adverse effects:
• GI effects: May cause GI upset (eg, nausea, vomiting, diarrhea, abdominal pain, discomfort) and lead to GI ulceration, bleeding, perforation and/or obstruction.
• Hyperkalemia: Close monitoring of serum potassium concentrations is needed to avoid hyperkalemia; severe hyperkalemia may lead to muscle weakness/paralysis and cardiac conduction abnormalities (eg, heart block, ventricular arrhythmias, asystole).
• Acid/base disorders: Use with caution in patients with acid/base alterations; changes in serum potassium concentrations can occur during acid/base correction, monitor closely.
• Cardiovascular disease: Use with caution in patients with cardiovascular disease (eg, heart failure, cardiac arrhythmias); patients may be more susceptible to life-threatening cardiac effects associated with hyper/hypokalemia.
• Hepatic impairment: Citrate is converted to bicarbonate in the liver; this conversion may be blocked in patients in hepatic failure.
• Potassium-altering conditions/disorders: Use with caution in patients with disorders or conditions likely to contribute to altered serum potassium and hyperkalemia (eg, untreated Addison's disease, heat cramps, severe tissue breakdown from trauma or burns).
• Renal impairment: Use with caution in patients with renal impairment; monitor serum potassium concentrations closely. Contraindicated with severe impairment.
• Severely ill: Citrate is converted to bicarbonate in the liver; this conversion may be blocked in patients who are severely ill or in shock.
Concurrent drug therapy issues:
• Digitalis: Use with caution in digitalized patients; may be more susceptible to potentially life-threatening cardiac effects with rapid changes in serum potassium concentrations.
• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.
Serum electrolytes (potassium, chloride, sodium), bicarbonate, serum creatinine, and CBC every 4 months (more frequently with cardiac/renal disease or acidosis); urinary citrate and/or urinary pH at initiation or dose change and every 4 months; ECG (periodically)

• Tablet shell in stool
• Abdominal pain
WARNING/CAUTION: Even though it may be rare, some people may have very bad and sometimes deadly side effects when taking a drug. Tell your doctor or get medical help right away if you have any of the following signs or symptoms that may be related to a very bad side effect:
• High potassium like abnormal heartbeat, confusion, dizziness, passing out, weakness, shortness of breath, numbness or tingling feeling
• Severe loss of strength and energy
• Abdominal swelling
• Black, tarry, or bloody stools
