potassium citrate/citric acid
oral solution
- (1100mg/334mg)/5mL
- Contains 2 mEq/mL potassium ion equivalent to 2 mEq/mL bicarbonate (HCO3)
Urinary Alkalinization
Indicated for long-term maintenance of an alkaline urine (eg, patients with uric acid and cystine calculi of the urinary tract), especially when the administration of sodium salts is undesirable or contraindicated

Pregnancy & Lactation
Pregnancy Category: C
Lactation: Unknown whether distributed in breast milk
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Potassium citrate is absorbed and metabolized to potassium bicarbonate and this acts as a systemic alkalizer
Elimination
Excretion: Oxidation of potassium citrate is virtually complete so <5% is excreted in the urine unchanged

POTASSIUM CITRATE/CITRIC ACID - ORAL
(poe-TAS-ee-um SI-trate/SIT-rik AS-id)
COMMON BRAND NAME(S): Polycitra-K
USES: This medication is used to make the urine less acidic. This effect helps the kidneys get rid of uric acid, thereby helping to prevent gout and kidney stones. This medication can also prevent and treat certain metabolic problems (acidosis) caused by kidney disease.Citric acid and citrate salts (which contain potassium and sodium) belong to a class of drugs known as urinary alkalinizers. If you have a condition that requires you to limit your intake of potassium and sodium, your doctor may direct you to take a product that is lower in potassium and sodium.
HOW TO USE: Take this medication by mouth as directed by your doctor, usually 4 times a day after meals and at bedtime. To help prevent diarrhea, take each dose after a meal. To prevent stomach upset/injury, mix your prescribed dose of medication in cold water or juice as directed. Drink the entire mixture slowly. If you still have stomach upset, mixing your dose in a larger amount of liquid may help unless your doctor directs you otherwise. Ask your doctor or pharmacist for further instructions.The liquid form of this medication must be mixed with at least 4 - 8 ounces (120 - 240 milliliters) of water before taking. Shake the bottle well before each dose and carefully measure the dose using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose. If you are using the powdered/crystal form of this medication, mix the contents of the packet in at least 3/4 cup (6 ounces or 180 milliliters) of cool water or juice before taking.Refrigerating the mixture before drinking may improve the taste. Drink more water or juice after taking this medication unless otherwise directed by your doctor.Dosage is based on your medical condition and response to treatment.Take this medication exactly as prescribed. Do not increase your dose or take this more often without your doctor's approval. Use this medication regularly to get the most benefit from it. To help you remember, take it at the same times each day.While taking this medication, you may need to test the pH (acidity) of your urine using special paper. The pH will help determine the proper dose. Consult your doctor or pharmacist for more information.
SIDE EFFECTS: Nausea, vomiting, diarrhea, and stomach pain may occur. Mixing the medication with water or juice, taking it after meals, and drinking more fluids will help prevent these side effects.
