The FDA has approved a product called Dextrose 70% in a plastic container. It is a concentrated sugar solution given through a vein. It is used in adults and children as a source of calories and water for hydration. Doctors use it when a person cannot get enough nutrition or fluids by eating or drinking.
This is a hospital-style treatment, not something you use at home. The dose is set by the treating doctor and adjusted for each person's age, weight, health, and lab test results. Because the solution is very concentrated, the label calls for frequent lab tests and close watching of blood sugar, electrolytes, and fluid balance during long treatment.
The label also includes safety warnings. Giving too much fluid or solute can cause problems. Long use in people with poor kidney function can raise the risk of aluminum buildup. Using a sugar solution without potassium can lead to low potassium. When given through a small vein, it should go in slowly to reduce vein irritation, and the care team must avoid leakage into nearby tissue.
There are no trial data in the label. If you have questions about this treatment, talk with your doctor. It is not a do-it-yourself product, and it is not right for everyone.
