Excessive administration of an isotonic solution of sodium chloride can cause hypernatremia. Excessive intake of chloride into the body can lead to hyperchloremic acidosis. If isotonic sodium chloride solution is used as a base solution for the dilution and transport of other drugs, symptoms and complaints with excessive administration are most often associated with the properties of the drugs added to the solution. In case of unintended excess solution administration, treatment should be discontinued and the patient's condition assessed.
Treatment: symptomatic.
