Sodium chloride injection is fine to drink.
Clinically, sodium chloride injection is also called saline, and saline is a 0.9% aqueous solution of sodium chloride, because its osmolality value is roughly the same as normal human plasma and tissue fluids, so it can be used as a rehydration solution (which does not decrease and increase the concentration of sodium ions in the body of a normal human being), as well as for other medical purposes. It is the concentration of the fluid environment in which the body’s cells are held. It is drinkable.
However, sodium chloride injection is generally administered as an intravenous infusion and is not as effective when consumed, so it is generally not recommended that it be used in this way by drinking sodium chloride injection.
The use of sodium chloride injection should only be under the guidance of professional medical personnel, because too much infusion, too fast, can lead to water and sodium retention, which can cause edema, elevated blood pressure, increased heart rate, chest tightness, dyspnea, etc., and even acute left heart failure and other adverse reactions.
