Water for Injection (WFI) is sterile, pyrogen-free, ultrapure water specifically prepared for use in medical and pharmaceutical applications. It is used primarily as a solvent to dilute or dissolve drugs before administration, especially for intravenous (IV), intramuscular (IM), or subcutaneous (SC) injections.
Key Characteristics of WFI:
Sterile & Pyrogen-Free: Ensures no bacteria or fever-causing contaminants.
No Additives or Electrolytes: It contains no sodium, potassium, or other dissolved substances.
Hypotonic: Cannot be injected directly into the bloodstream, as it can cause hemolysis (destruction of red blood cells).
Used in manufacturing medical solutions, such as IV fluids or parenteral nutrition.
WFI is not used as a direct replacement for saline or dextrose solutions because it lacks electrolytes and can disrupt cell balance if injected alone.
The main difference between NaCl 0.9% (Normal Saline) and Water for Injection (WFI) is their composition and use in medical applications:
1. NaCl 0.9% (Normal Saline)
Contains sodium chloride (salt) dissolved in water at a concentration of 0.9%, making it isotonic with blood.
Used for fluid replacement, diluting medications, and IV infusions to maintain electrolyte balance.
Safe for direct injection into the bloodstream.
2. Water for Injection (WFI)
Pure, sterile water without any additives or electrolytes.
Used for reconstituting medications (mixing with powdered drugs) but not for direct IV injection alone because it can cause hemolysis (rupture of red blood cells) due to its hypotonic nature.
Often combined with other solutions before administration.
Key Takeaway:
Use NaCl 0.9% when electrolyte balance is needed.
Use WFI only for diluting medications before administration, not for direct IV use.

Hypotonic: Cannot be injected directly into the bloodstream, as it can cause hemolysis (destruction of red blood cells).
Common Uses:
Reconstituting powdered medications (e.g., antibiotics, vaccines).
Diluting injectable drugs before administration.
Used in manufacturing medical solutions, such as IV fluids or parenteral nutrition.
