Store in a cool, dry place.
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. 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
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. 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. Oral liquid preparations (not solid) should be used in patients with esophageal compression or delayed gastric emptying.
• 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.
• Potassium-altering therapies: Use with caution in patients receiving concomitant medications or therapies that increase potassium (eg, ACEI, potassium-sparing diuretics, potassium containing salt substitutes).
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)

• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience diarrhea or tablet shell in stool. Have patient report immediately to prescriber signs of high potassium (abnormal heartbeat, confusion, dizziness, passing out, weakness, shortness of breath, numbness or tingling feeling), abdominal edema, severe nausea, severe vomiting, severe abdominal pain, black, tarry, or bloody stools, or vomiting blood (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
