Generally speaking, it is not recommended to drink 50% dextrose directly in daily life. If you have the need for examination or treatment, you can take it under the guidance of your doctor. 50% dextrose, also known as hyperosmolar solution, is a hypertonic solution suitable for replenishing energy and body fluids (e.g., large fluid loss from various causes and insufficient food intake), treating hypoglycemia, hyperkalemia, starvation ketosis or can be used to perform glucose tolerance test examination. However, 50% Dextrose is contraindicated in uncontrolled diabetic ketoacidosis, hyperglycemic non-ketotic hyperosmolar state. And, adverse reactions such as phlebitis, localized swelling and pain may occur after intravenous administration. Patients who need to use 50% Dextrose should be under the supervision of a doctor.
