About POTASSIUM CITRATE

What is this medication? Potassium citrate is a prescription medication primarily used to manage certain types of kidney stones, specifically those composed of uric acid or calcium oxalate. It belongs to a class of medications known as urinary alkalinizers. By increasing the pH level of the urine, this medication makes the environment less acidic, which helps prevent the formation of new crystals and can assist in preventing existing stones from growing larger.

In addition to its role in kidney stone management, potassium citrate is often prescribed to treat a condition known as renal tubular acidosis. It works by providing a supplemental source of potassium and citrate, which the body converts into bicarbonate to help neutralize excess acid in the blood and urine. Patients are generally advised to take this medication with food and plenty of fluids to maximize its benefits and reduce the risk of stomach irritation.

Prescribing information

From the FDA-approved label for POTASSIUM CITRATE. Official source: DailyMed (NLM) · Label effective Nov 19, 2024

Indications and usage

INDICATIONS AND USAGE Potassium Citrate and Citric Acid Oral Solution USP is an effective alkalinizing agent useful in those conditions where long-term maintenance of an alkaline urine is desirable, such as in patients with uric acid and cystine calculi of the urinary tract, especially when the administration of sodium salts is undesirable or contraindicated. In addition, it is a valuable adjuvant when administered with uricosuric agents in gout therapy, since urates tend to crystallize out of an acid urine. It is also effective in correcting the acidosis of certain renal tubular disorders where the administration of potassium citrate may be preferable. This product is highly concentrated, and when administered after meals and before bedtime, allows one to maintain an alkaline urinary pH around the clock, usually without the necessity of a 2 A.M. dose. This product alkalinizes the urine without producing a systemic alkalosis in recommended dosage. It is highly palatable, pleasant tasting and tolerable, even when administered for long periods. Potassium citrate does not neutralize the gastric juice or disturb digestion.

Dosage and administration

DOSAGE AND ADMINISTRATION Potassium Citrate and Citric Acid Oral Solution USP should be taken diluted in water according to directions, followed by additional water, if desired. Palatability is enhanced if chilled before taking. Usual Adult Dose 3 to 6 teaspoonfuls (15 to 30 mL), diluted with 1 glass of water, after meals and at bedtime, or as directed by a physician. Usual Pediatric Dose 1 to 3 teaspoonfuls (5 to 15 mL), diluted with 1/2 glass of water, after meals and at bedtime, or as directed by a physician. Usual Dosage Range 2 to 3 teaspoonfuls (10 to 15 mL), diluted with a glassful of water, taken four times a day. Potassium Citrate and Citric Acid Oral Solution USP, diluted with a glassful of water, taken four times a day will usually maintain a urinary pH of 7.0-7.6 throughout most of the 24 hours without unpleasant side effects. To check urinary pH, HYDRION Paper (pH 6.0-8.0) or NITRAZINE Paper (pH 4.5-7.5) are available and easy to use.

Contraindications

CONTRAINDICATIONS Severe renal impairment with oliguria or azotemia, untreated Addison's disease, adynamia episodica hereditaria, acute dehydration, heat cramps, anuria, severe myocardial damage, and hyperkalemia from any cause.

Warnings

WARNINGS Large doses may cause hyperkalemia and alkalosis, especially in the presence of renal disease. Concurrent administration of potassium-containing medication, potassium-sparing diuretics, angiotensin-converting enzyme (ACE) inhibitors, or cardiac glycosides may lead to toxicity.

Adverse reactions

ADVERSE REACTIONS Potassium Citrate and Citric Acid Oral Solution USP is generally well tolerated without any unpleasant side effects when given in recommended doses to patients with normal renal function and urinary output. However, as with any alkalinizing agent, caution must be used in certain patients with abnormal renal mechanisms to avoid development of hyperkalemia or alkalosis. Potassium intoxication causes listlessness, weakness, mental confusion, tingling of extremities, and other symptoms associated with a high concentration of potassium in the serum. Periodic determinations of serum electrolytes should be carried out in those patients with renal disease in order to avoid these complications. Hyperkalemia may exhibit the following electrocardiographic abnormalities: Disappearance of the P wave, widening and slurring of QRS complex, changes of the S-T segment, tall peaked T waves, etc. To report SUSPECTED ADVERSE REACTIONS, contact Pharmaceutical Associates, Inc. at 1-800-845-8210 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
