From the Guidelines

It is not recommended to give sodium chloride 1 g three times a day, even for one day, as this exceeds the daily recommended intake for certain populations, such as children and individuals with hypertension or kidney disease. When considering sodium chloride supplementation, it's essential to take into account the individual's overall health status, age, and any pre-existing medical conditions. According to the KDOQI clinical practice guideline for nutrition in children with CKD, the recommended daily sodium intake is less than 2,400 mg (104 mmol) 1. The most recent guidelines even suggest limiting sodium intake to less than 2,000 mg (87 mmol) per day.

  • The proposed dose of 1 g of sodium chloride three times a day would provide approximately 3.6 g of sodium chloride, which is equivalent to about 1.44 g of sodium (since sodium makes up about 40% of sodium chloride by weight).
  • This dose is relatively high, especially for certain populations, such as children, who have much lower recommended daily sodium intakes.
  • For example, the recommended daily sodium intake for children aged 1-3 years is 1,500 mg (65 mmol), and for children aged 4-8 years, it is 1,900 mg (82 mmol) 1.
  • Additionally, individuals with certain medical conditions, such as hypertension, heart failure, or kidney disease, may need to restrict their sodium intake even further.
  • It's also important to consider the source of sodium in the diet, as the majority of sodium intake comes from processed and manufactured foods, rather than from added salt at the table or during cooking 1.
  • Therefore, it's crucial to carefully evaluate the individual's overall sodium intake and health status before considering any sodium chloride supplementation, and to consult with a healthcare provider for personalized guidance.

From the FDA Drug Label

The dosage of Sodium Chloride Oral Solution 23.4% is predicated on the specific requirements of the patient based on clinical and laboratory information. The FDA drug label does not answer the question.

From the Research

Sodium Chloride Administration

  • The administration of sodium chloride 1 g three times a day is not directly addressed in the provided studies 2, 3, 4, 5, 6.
  • However, the studies discuss the importance of sodium intake in various contexts, such as rehydration in diarrheal illness 2, maintaining hydration during exercise 2, and intravenous fluid management in critically ill adults 3, 4, 5.
  • The study by 4 found that reducing sodium loading in critically ill patients can be safely achieved by using 5% glucose as a diluent for infusions and boluses, and as a maintenance fluid.
  • Another study 5 discusses the pharmacokinetic and pharmacodynamic effects of infusion fluids, including normal saline solution, and highlights the importance of careful consideration in selecting infusion fluids to avoid electrolyte and acid-base disturbances.
  • There is no direct evidence to support or refute the administration of sodium chloride 1 g three times a day as a single dose.
  • It is essential to consider the individual's specific needs, medical condition, and other factors before administering any medication or supplement, including sodium chloride.
