Question

Why Water for injection should be used immediately after its preparation ?​

Answer 1

Answer:

Water for injection is water of extra high quality without significant contamination.[1] A sterile version is used for making solutions that will be given by injection.[2] Before such use other substances generally must be added to make the solution more or less isotonic.[3] It can be given by injection into a vein, muscle, or under the skin.[4] A non-sterile version may be used in manufacturing with sterilization occurring later in the production process.[5]
