Potassium citrate is a citrate salt of potassium indicated for the management of: Renal tubular acidosis (RTA) with calcium stones ( 1.1 ) Hypocitraturic calcium oxalate nephrolithiasis of any etiology ( 1.2 ) Uric acid lithiasis with or without calcium stones ( 1.3 ) 1.1 Renal Tubular Acidosis (RTA) with Calcium Stones Potassium citrate is indicated for the management of renal tubular acidosis [see Clinical Studies ( 14.1 )]. 1.2 Hypocitraturic Calcium Oxalate Nephrolithiasis of any Etiology Potassium citrate is indicated for the management of Hypocitraturic calcium oxalate nephrolithiasis [see Clinical Studies ( 14.2 )]. 1.3 Uric Acid Lithiasis with or without Calcium Stones Potassium citrate is indicated for the management of Uric acid lithiasis with or without calcium stones [see Clinical Studies ( 14.3 )].

Potassium citrate extended- release tablets are contraindicated: In patients with hyperkalemia (or who have conditions predisposing them to hyperkalemia), as a further rise in serum potassium concentration may produce cardiac arrest. Such conditions include: chronic renal failure, uncontrolled diabetes mellitus, acute dehydration, strenuous physical exercise in unconditioned individuals, adrenal insufficiency, extensive tissue breakdown or the administration of a potassium-sparing agent (such as triamterene, spironolactone or amiloride). In patients in whom there is cause for arrest or delay in tablet passage through the gastrointestinal tract, such as those suffering from delayed gastric emptying, esophageal compression, intestinal obstruction or stricture, or those taking anticholinergic medication. In patients with peptic ulcer disease because of its ulcerogenic potential. In patients with active urinary tract infection (with either urea-splitting or other organisms, in association …

Hyperkalemia: In patients with impaired mechanisms for excreting potassium, potassium citrate administration can produce hyperkalemia and cardiac arrest. Potentially fatal hyperkalemia can develop rapidly and be asymptomatic. The use of potassium citrate in patients with chronic renal failure, or any other condition which impairs potassium excretion such as severe myocardial damage or heart failure, should be avoided ( 5.1 ) Gastrointestinal lesions: if there is severe vomiting, abdominal pain or gastrointestinal bleeding, potassium citrate should be discontinued immediately and the possibility of bowel perforation or obstruction investigated ( 5.2 ) 5.1 Hyperkalemia In patients with impaired mechanisms for excreting potassium, potassium citrate administration can produce hyperkalemia and cardiac arrest. Potentially fatal hyperkalemia can develop rapidly and be asymptomatic. The use of potassium citrate in patients with chronic renal failure, or any other condition which impairs potassium excretion such as severe myocardial damage or heart failure, should be avoided. Closely monitor for signs of hyperkalemia with periodic blood tests and ECGs. 5.2 Gastrointestinal Lesions Solid dosage forms of potassium chlorides have produced stenotic and/or ulcerative lesions of the small bowel and deaths. These lesions are caused by a high local concentration of potassium ions in the region of the dissolving tablets, which injured the bowel. In addition, perhaps because wax-matrix …

8.1 Pregnancy Animal reproduction studies have not been conducted. It is also not known whether potassium citrate can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Potassium citrate should be given to a pregnant woman only if clearly needed.
