This injection is essentially 0.9% sodium chloride (NaCl) dissolved in sterile water—with 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 won’t 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 it’s free from substances that cause fever, and it’s intended for parenteral use (injection). Because it’s a USP-grade preparation, it meets quality standards for purity and sterility required for injectable solutions
