What should I know about KCl in NS before using it?

KCl in NS should only be administered by a trained professional to hospitalized people who cannot eat or drink normally. If too much of this solution is injected, the result can be overhydration, congestion or fluid buildup in the lungs. This solution should be used with great care or not at all in people with kidney problems or failure, congestive heart failure, high blood volume, a urinary tract obstruction, sodium retention with edema, potassium retention or high blood potassium levels. Other drugs may interact with KCl in NS, so it's important for the administering doctor to know about all medications and supplements that the patient is taking. This drug may be administered alongside other vitamins and minerals for proper nutrition. KCl in NS may cause harm to developing fetuses if taken by pregnant women, and should be used with great caution in infants and children.
