Q: Does ure-Na have a billing code?

A: Yes ure-Na has a billing code that is used in place of an NDC. The code is: 62530-0000-11

Q: How does ure-Na work?

A: ure-Na is USP urea with a proprietary flavor and taste masking formula, which makes it palatable. It is used for the management of hyponatremia. It is known that hyponatremia is rarely a sodium deficiency, but rather an excess of water in the blood relative to sodium. Urea normalizes blood sodium levels by inducing water loss in the urine. This is accomplished without a risk of loss of important electrolytes like potassium, calcium and magnesium. Treatment with urea is particularly helpful in cases of SIADH (Syndrome of inappropriate ADH Secretion).

Q: What is ure-Na used for?

A: ure-Na is a medical food used to treat euvolemic and hypervolemic hyponatremia, including SIADH.

Q: Do any guidelines support the use of urea for the management of hyponatremia?

A: Guidelines from the European Society of Endocrinology, The European Society of Intensive Care Medicine, and The European Renal Association- EDTA support the use of urea for the management of hyponatremia:(click for link)http://www.eje-online.org/content/170/3/G1.full.pd... UpToDate has also reviewed the use of urea in hyponatremia and has recommendations on dosing.(click for link) http://www.uptodate.com/contents/overview-of-the-treatment-of-hyponatremia-in-adults

Q: What is the efficacy of urea, how well does it raise sodium?

A: In a comparison study of urea versus vaptans , urea had similar efficacy raising serum sodium to 135 mEq/L. (Soupart A: Efficacy and Tolerance of Urea Compared with Vaptans for Long-Term Treatment of Patients with SIADH. CJASN Vol 7 May, 2012.) In another study of the use of urea in an ICU setting, urea raised serum sodium 4 mmol/L the first day of use, and 7 mmol/L in 48 hours. (Decaux et al: Treatment of euvolemic hyponatremia in the intensive care unit by urea., Critical Care 2010 14:R184.) This rate of rise is very important from a safety standpoint, because too rapid a rise of serum sodium levels can be dangerous, and even life threatening. The above study showed that the rise was within the recommended levels of raising serum sodium levels less than 9mmol/L in the first 24 hours.

Q: Is there an AMCP Dossier for ure-Na?

A: Yes, please fill out the contact form in the contact section and we'll send you the dossier.

Q: What are the risks of taking urea?

A: The risks of taking urea are very low. No long term toxicity has been seen. There is a very low risk of hypernatremic dehydration if your patients thirst center is intact. (Decaux G: Urea for long term treatment of syndrome of inappropriate secretion of antidiuretic hormone. BMJ Vol 283 24 Oct 1981.)

Q: How much water or juice is mixed with a 15g dose or ure-Na?

A: A 15g dose of ure-Na easily mixes into solution in 3-4 ounces of water or juice. As you know, hyponatremia can be a difficult condition to manage. We recommend that ure-Na be taken under medical supervision and that the amount of water or juice that ure-Na is mixed with is determined by the health care provider.

Q: How is ure-Na packaged?

A: Each 15g dose of urea in a serving of ure-Na is individually packaged in easy to open pouches. There are 8 pouches or doses per box.

Q: Can ure-Na be used with other therapeutic options to treat hyponatremia?

A: As each patients therapeutic needs are different, this determination will need to be made by the health care provider

Q: How is ure-Na dosed?

A: The European guidelines* on the use if urea recommend a dose of 0.25-0.50g/Kg (a 140lb person then would take 15.75 - 31.5g) UpToDate discusses a daily dose of 30g.

Q: How does my patient get ure-Na for outpatient use?

A: ure-Na may be covered by health insurance through Prior Authorization. If ure-Na is not covered by insurance, it may be a tax deductible qualified medical expense.

Dosing for a Prior Auth: ure-Na is packaged in 8 count boxes. If a patient is on 15g/day the dispensing request on the PA will be ure-Na 8 count x 4. If the patient is on 15g/BID (30g/day) the dispensing request will be ure-Na 8 count x 8. The Billing code used in place of an NDC is:62530-0000-11

If insurance approves ure-Na it can be order at most local pharmacies. If a pharmacy is having difficulty ordering ure-Na since it is new, please call us at 1-844-980-9933, so we can get ure-Na transferred to that pharmacy.

If ure-Na is not covered by health insurance, it can be ordered at most retail pharmacies, or at www.ure-na.com.

Q: What degree of hyponatremia can ure-Na be used for?

A: The European Guidelines* recommend the use of urea in moderate to profound hyponatremia.

Q: What are the side effects of taking ure-Na?

A: Mild GI upset has been seen in a minority of patients taking urea.

Q: Is urea nephrotoxic or hepatotoxic like other therapeutic options for the managing hyponatremia?

A: Urea is not nephrotoxic or hepatotoxic like other therapeutic options for the management of hyponatremia.

Q: Does urea have a risk of toxicity if used in the long term?

A: There is data on the use of urea in doses of 15g and 30g per day for 1 year that show no toxicity. (Soupart A:Efficacy and Tolerance of Urea Compared with Vaptans for Long Term Treatment of Patients with SIADH. CJASN Vol 7 May, 2012)

Q: What is a Medical Food?

A: Unlike supplements a medical food, as defined in section 5(b)(3) of the Orphan Drug Act (21 U.S.C. 360ee(b)(3)), is “a food which is formulated to be consumed or administered enterally under the supervision of a physician and which is intended for the specific dietary management of a disease or condition for which distinctive nutritional requirements, based on recognized scientific principles, are established by medical evaluation.” Medical Foods, including ure-Na can be purchased OTC without a prescription. Ure-Na is made in the USA in an FDA inspected facility under cGMP guidelines.

Q: How does the FDA Classify urea?

A: The FDA classifies urea as GRAS or Generally Recognized As Safe. This is a designation that a chemical or substance added to food is considered safe by experts, and so is exempted from the usual Federal Food, Drug and Cosmetic Act (FFDCA) food additive tolerance requirements.
