How to Administer Sodium Chloride Tablets
Sodium chloride tablets (500 mg capsules) should be taken in high doses of 14 capsules per 24 hours, distributed throughout the day before meals, though they may cause nausea and vomiting in some patients 1.
Administration Guidelines
Dosing and Timing
- Standard dose: 14 capsules of 500 mg each per 24 hours (total 7,000 mg/day) 1
- Take before meals to reduce intestinal secretions that increase after eating 1
- Distribute doses throughout the day rather than taking all at once
For Patients with High Stoma Output
When managing patients with jejunostomy or ileostomy outputs of 1200-2000 mL daily:
- Salt capsules are an alternative to glucose-saline solutions 1
- The goal is to maintain sodium balance when stomal losses contain approximately 90 mmol/L of sodium 1
- Oral fluid restriction to less than 1 liter per day should accompany salt supplementation 1
Alternative Formulations
If using concentrated oral solution (23.4%):
- Adults ages 9-50: 4 mL (equivalent to 936 mg sodium chloride) 2
- Children under 9 and adults over 50: Consult physician for dosing 2
- Store at room temperature 20-25°C 2
- Discard opened product after 90 days 2
Important Caveats
Managing Intolerance
If tablets cause nausea or vomiting (a common problem):
- Consider switching to glucose-saline solution instead 1
- If tablets emerge unchanged in stool/stomal output, crush them, open capsules, mix with water, or put on food 1
When Salt Tablets Are Most Effective
Salt capsules work best when:
- Stomal losses are 1200-2000 mL daily 1
- Patient can tolerate the high pill burden
- Combined with appropriate fluid restriction 1
Alternative Approach
For patients who cannot tolerate capsules, glucose-saline solution (WHO cholera solution at 90 mmol/L sodium concentration) sipped throughout the day is equally effective and often better tolerated 1. This can be chilled or flavored with fruit juice for palatability 1.
Clinical Context
The high dose requirement (14 capsules daily) reflects the need to replace substantial sodium losses in patients with short bowel syndrome or high-output stomas. The sodium content of jejunostomy effluent remains constant at approximately 90 mmol/L, requiring aggressive replacement 1. In hot weather, requirements may increase further due to additional sweat losses 1.
