Can water for injection be administered intravenously?
Water for injection is a sterile solvent primarily used to dilute or dissolve medications for administration into the body via injection. Generally, water for injection should not be used directly for intravenous injection. Specific details are as follows:
Water for injection is typically not suitable for direct intravenous use. In clinical practice, it is commonly used to dissolve powdered drugs or mixed with other injectable solutions before intravenous administration, and is more frequently applied in intramuscular or subcutaneous injections. Since water for injection does not contain electrolytes and has low osmotic pressure, administering it alone via intravenous injection not only fails to supply substances essential to the body but may also disrupt the body's osmotic balance, posing risks to health.
To ensure safe and effective intravenous administration, appropriate solvents such as normal saline or glucose injection solution should be used instead of water for injection. Patients experiencing discomfort should seek medical attention promptly and receive standardized treatment under a physician’s guidance, which helps promote recovery.
