AI Summary Generated by AI for informational purposes only

This is sterile water used for dissolving or diluting other medicines before they are injected. It is considered safe during pregnancy and breastfeeding, but its use depends on the safety of the medicine it is mixed with.

Indications

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

Pharmacology

If it is given by injection into a vein without making it more or less isotonic, breakdown of red blood cells may occur. This can then result in kidney problems. Excessive amount may also result in fluid overload. Water for injection is generally made by distillation or reverse osmosis. It should contain less than a mg of elements other than water per 100 ml. Versions with agents that stop bacterial growth are also available
