Full prescribing information FDA SPL
🎯 Indications and Usage ▾
INDICATIONS AND USAGE Sodium Citrate and Citric Acid Oral Solution USP is an effective alkalinizing agent. It is useful in those conditions where long-term maintenance of an alkaline urine is desirable, and is of value in the alleviation of chronic metabolic acidosis, such as results from chronic renal insufficiency or the syndrome of renal tubular acidosis, especially when the administration of potassium salts is undesirable or contraindicated. This product is also useful for buffering and neutralizing gastric hydrochloric acid quickly and effectively.
Sodium Citrate and Citric Acid Oral Solution USP is 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 the recommended dosage. This product is highly palatable, pleasant tasting, and tolerable, even when administered for long periods.
⏱️ Dosage and Administration ▾
DOSAGE AND ADMINISTRATION Sodium Citrate and Citric Acid Oral Solution USP should be taken diluted in water, followed by additional water, if desired. SHAKE WELL BEFORE USING.
⛔ Contraindications ▾
CONTRAINDICATIONS Patients on sodium-restricted diets or with severe renal impairment.
🤒 Adverse Reactions ▾
ADVERSE REACTIONS Sodium 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 alkalosis, especially in the presence of hypocalcemia. 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..
🆘 Overdosage ▾
OVERDOSAGE Overdosage with sodium salts may cause diarrhea, nausea and vomiting, hypernoia, and convulsions.
🧬 Clinical Pharmacology ▾
CLINICAL PHARMACOLOGY Sodium citrate is absorbed and metabolized to sodium bicarbonate, thus acting as a systemic alkalizer. The effects are essentially those of chlorides before absorption and those of bicarbonates subsequently. Oxidation is virtually complete so that less than 5% of sodium citrate is excreted in the urine unchanged.
📦 How Supplied / Storage and Handling ▾

📋 Description ▾
DESCRIPTION Sodium Citrate and Citric Acid Oral Solution USP is a stable and pleasant-tasting systemic alkalizer containing sodium citrate and citric acid in a sugar-free base. It is a nonparticulate neutralizing buffer. Sodium Citrate and Citric Acid Oral Solution USP contains in each teaspoonful (5 mL): SODIUM CITRATE Dihydrate 500 mg (0.34 Molar) CITRIC ACID Monohydrate 334 mg (0.32 Molar) Each mL contains 1 mEq sodium ion and is equivalent to 1 mEq bicarbonate (HCO3).
Sodium citrate contains the following inactive ingredients: flavoring, polyethylene glycol, propylene glycol, purified water, sodium benzoate, and sorbitol solution.
⚠️ Precautions ▾
PRECAUTIONS Sodium Citrate and Citric Acid Oral Solution USP should be used with caution by patients with low urinary output unless under the supervision of a physician. This product should not be administered concurrently with aluminum-based antacids. Patients should be directed to dilute adequately with water and preferably, to take each dose after meals to avoid saline laxative effect.
Sodium salts should be used cautiously in patients with cardiac failure, hypertension, impaired renal function, peripheral and pulmonary edema, and toxemia of pregnancy. Periodic examinations and determinations of serum electrolytes, particularly serum bicarbonate level, should be carried out in those patients with renal disease in order to avoid these complications.

About this NDC listing & data coverage
Listed without an FDA application
This product's marketing category indicates it is marketed without an approved FDA application (no NDA, ANDA, or BLA on file). Having an NDC does not by itself establish FDA approval — the NDC Directory is a listing system, not an approval decision. Approval-linked data such as Orange Book therapeutic-equivalence ratings therefore does not apply.
