Indications & Clinical Uses
- Ure-Na (15 g packet) is a flavoured oral urea powder sold in the USA as a medical food, meaning a product for use under a healthcare provider's supervision; it is not an FDA-approved prescription drug, and no approved-drug label exists for it.
- The manufacturer states it is for the dietary management of low blood sodium (hyponatraemia) that is euvolaemic (normal fluid volume) or hypervolaemic (excess fluid), including SIADH (syndrome of inappropriate antidiuretic hormone secretion).
- Urea works as an osmotic agent, helping the body pass excess free water without losing electrolytes.
- Each packet holds 15 g of USP urea to be mixed with a few ounces of water or juice.
- Typical outpatient doses described by the manufacturer are 15 g once or twice daily, but your healthcare provider decides the dose from your blood sodium tests.
Side Effects
- According to the manufacturer and a drug-information summary, the most common problems are an unpleasant taste (about 2% of hospitalised patients could not tolerate it), nausea or mild stomach upset (about 5%) and vomiting (under 1%).
- Serious problems are those of over-correcting fluid and salt balance, such as high blood sodium (hypernatraemia) or fluid and electrolyte imbalance, which can cause confusion, muscle weakness, an abnormal heartbeat or severe dizziness.
- Seek urgent help for confusion, seizures, fast or irregular heartbeat, hives, rash or breathing difficulty.
- No boxed warning applies because Ure-Na is a medical food, not a labelled drug.
- Splitting the dose or using more fluid can help if the taste or stomach upset is a problem.
Precautions & Warnings
- Use Ure-Na only under the supervision of a healthcare provider, with regular blood sodium monitoring.
- The manufacturer states it is not for hypovolaemic (low fluid volume) hyponatraemia, hyponatraemia due to adrenal insufficiency, or hyperammonaemia (high blood ammonia).
- Report mood changes, muscle pain, dizziness, seizures, poor appetite, changes in urination or allergic symptoms.
- Mix a packet with about 3 to 4 ounces of water or juice (6 to 8 ounces if tolerance is poor); it may be taken with food or applesauce but should not be taken with hot liquids.
- The manufacturer does not give information on pregnancy, breastfeeding, driving or storage, so ask your healthcare provider or pharmacist.
- Ure-Na is sodium-free according to the manufacturer.
Avoid Interactions
- The manufacturer and Drugs.com report no known significant drug interactions for urea, and no interaction studies were found, so safe combinations cannot be assumed.
- Because urea changes how the body handles water and sodium, your healthcare provider will interpret blood sodium results in light of everything else you take, including any fluid restriction.
- Do not mix the powder with hot liquids.
- Tell your healthcare provider about all prescription medicines, over-the-counter medicines, herbal products and supplements you use, and do not change how you take Ure-Na without advice.
