STERILE WATER FOR INJECTION IN PLASTIC CONTAINER

STERILE WATER FOR INJECTION IN PLASTIC CONTAINER

Clinical safety rating

caution

Comprehensive clinical and safety monograph for STERILE WATER FOR INJECTION IN PLASTIC CONTAINER (STERILE WATER FOR INJECTION IN PLASTIC CONTAINER).


Mechanism of Action

Water is a solvent and diluent for parenteral administration; it provides hydration and maintains osmotic balance. It has no pharmacological activity.

What the body does with it

MetabolismWater is not metabolized; it is distributed throughout body fluids and excreted primarily by the kidneys.
ExcretionRenal: >99% as free water; biliary/fecal: negligible
Half-lifeApproximately 30-45 minutes; rapid redistribution due to constant renal clearance; clinically, water half-life is not typically measured since it is a vehicle
Protein binding0% (water does not bind to plasma proteins)
Volume of Distribution0.55-0.7 L/kg (total body water); clinically, water distributes throughout total body water
BioavailabilityIntravenous: 100%; subcutaneous: ~100% (complete absorption); intramuscular: ~100%
Onset of ActionIntravenous: immediate upon infusion; subcutaneous: within seconds to minutes depending on injection site absorption
Duration of ActionIntravenous: effect persists only during infusion and for minutes afterward due to rapid renal excretion; subcutaneous: variable, typically minutes to hours depending on volume and absorption rate (e.g., 15-30 minutes for small volumes)
Molecular Weight18.015

Classification & Brands

Dosing & administration

Intravenous administration; dose determined by clinical requirements for hydration, drug dilution, or vehicle for parenteral medications. Typical adult maintenance: 30 mL/kg/day, adjusted for electrolyte and fluid status.

Dosage formLIQUID
Renal impairmentNo specific GFR-based dose adjustment; monitor fluid balance and avoid fluid overload in renal impairment. In oliguric or anuric patients (GFR <10 mL/min), reduce volume to match insensible losses plus urine output.
Liver impairmentNo specific Child-Pugh based modification; use with caution in ascites or edema due to risk of fluid overload.
Pediatric useWeight-based: Neonates and infants: 60-100 mL/kg/day for maintenance; adjust for dehydration or ongoing losses. Administer via intravenous route.
Geriatric useUse lower end of dosing range due to decreased renal function and comorbidities; monitor for fluid overload and electrolyte disturbances. Typical starting dose: 20-30 mL/kg/day intravenously.

Use during pregnancy

1st trimesterNo evidence of fetal harm; considered safe when administered as a vehicle for compatible medications.
2nd trimesterNo evidence of fetal harm; considered safe when administered as a vehicle for compatible medications.
3rd trimesterNo evidence of fetal harm; considered safe when administered as a vehicle for compatible medications.

Clinical note

Comprehensive clinical and safety monograph for STERILE WATER FOR INJECTION IN PLASTIC CONTAINER (STERILE WATER FOR INJECTION IN PLASTIC CONTAINER).

Placental transferWater freely crosses the placenta via passive diffusion; no known adverse fetal effects from water itself.
BreastfeedingSterile water for injection is considered compatible with breastfeeding when used as a vehicle for medications. Excretion into breast milk is negligible and not expected to cause adverse effects in the infant.
Lactation RatingL1 (Safe)
Teratogenic RiskSterile Water for Injection is a parenteral fluid devoid of pharmacologic activity. There is no known teratogenic risk across all trimesters; water is an essential nutrient with no expected fetal harm when administered appropriately.
Fetal MonitoringStandard monitoring of maternal vital signs, fluid balance, and injection site assessment. Fetal heart rate monitoring not specifically required unless administered in large volumes for maternal resuscitation.
Fertility EffectsNo known effects on fertility; water administration does not influence reproductive function.

Warnings & precautions

■ FDA Black Box Warning

None.

Side Effect Profile

Serious Effects

Absolute Contraindications

None when used as intended; contraindicated if incompatible with specific additives or if the container is damaged.

Clinical Precautions

PrecautionsUse only if solution is clear and container is intact, Do not use for intravenous injections that require isotonic solutions unless additives are used to achieve isotonicity, Risk of hemolysis if administered as a large volume hypotonic solution, Monitor for fluid overload in patients with renal impairment or cardiac disease
Food/DietaryNo known food interactions. Patients on a sodium-restricted diet should be aware that this product contains no sodium.

Clinical Tips & Counseling

Clinical PearlsSterile water for injection is not intended for direct intravenous administration; it is used for reconstitution of medications or as a diluent. If given intravenously without proper tonicity adjustments, it can cause hemolysis, hyponatremia, and cerebral edema.
Patient AdviceThis product is used to mix with other medications before they are given as an injection or infusion. · Do not inject this water directly into a vein as it can cause serious side effects. · Tell your healthcare provider if you have any allergies or if you are on a sodium-restricted diet.
