This injection is essentially 0.9% sodium chloride (NaCl) dissolved in sterile waterwith 9 mg of sodium chloride per milliliter, making it isotonic with blood and tissues. The isotonic nature means it has the same salt concentration as normal body fluids, so it wont cause cells to shrink or swell when injected. In addition to salt,each milliliter contains about 9 mg of benzyl alcohol (0.9%) as the bacteriostatic agent. The benzyl alcohol does not treat infection, but its job is to keep the solution sterile by inhibiting bacterial growth if the vial is used more than once. The solution is labeled nonpyrogenic, meaning its free from substances that cause fever, and its intended for parenteral use (injection). Because its a USP-grade preparation, it meets quality standards for purity and sterility required for injectable solutions
