STERILE WATER FOR IRRIGATION
Clinical safety rating
cautionComprehensive clinical and safety monograph for STERILE WATER FOR IRRIGATION (STERILE WATER FOR IRRIGATION).
Sterile water for irrigation serves as an isotonic, non-pyrogenic irrigation solution that maintains osmotic equilibrium and does not provide systemic pharmacologic effects. It acts solely as a mechanical flushing agent to cleanse, rinse, or moisten tissues during surgical or other medical procedures.
| Metabolism | Not metabolized; sterile water for irrigation is typically not absorbed into systemic circulation when used as directed for topical irrigation. |
| Excretion | Renal: virtually 100% as unchanged water; no biliary or fecal elimination under normal conditions. Excess water is excreted via urine with minimal insensible losses (skin, lungs) not accounted as drug elimination. |
| Half-life | Not applicable as a drug; water distribution follows body water turnover. From a pharmacokinetic perspective, the elimination half-life of a water load is approximately 2-4 hours in adults with normal renal function, reflecting renal excretion of excess volume. |
| Protein binding | 0%; water does not bind to plasma proteins. |
| Volume of Distribution | Total body water: approximately 0.6 L/kg (range 0.5-0.7 L/kg) in adults. Distributes throughout all body fluid compartments. |
| Bioavailability | Oral: 100% (absorbed via gastrointestinal tract); intravenous: 100%; irrigation: negligible systemic absorption unless mucosal barrier is compromised; intraperitoneal: nearly 100% absorption. |
| Onset of Action | Irrigation: immediate upon contact with tissues; intravenous: immediate expansion of intravascular volume within minutes. |
| Duration of Action | Irrigation: localized effect only during application; intravenous: volume expansion lasts until excess water is excreted renally, typically 1-2 hours after a bolus. Rehydration effect may persist longer if volume deficit is corrected. |
| Molecular Weight | 18.015 |
Irrigation solution: apply topically to surgical sites or body cavities as needed, typically 1-3 L per procedure via gravity flow or low-pressure irrigation. Not for injection.
| Dosage form | LIQUID |
| Renal impairment | No adjustment necessary for topical irrigation use. For intravenous use (non-approved), adjust based on fluid status and electrolyte monitoring. |
| Liver impairment | No adjustment necessary for topical irrigation use. |
| Pediatric use | Irrigation solution: volume as clinically indicated based on wound size and procedure; typical range 10-50 mL/kg per irrigation event. |
| Geriatric use | Use with caution due to potential fluid overload; monitor urine output and pulmonary status. Volume as clinically indicated, but limit to minimal necessary. |
| 1st trimester | No known risk; sterile water is isotonic and non-pharmacologic. No fetal harm expected. |
| 2nd trimester | No known risk; use as indicated for irrigation. |
| 3rd trimester | No known risk; use as indicated for irrigation. Caution with large volumes to avoid fluid overload. |
Clinical note
Comprehensive clinical and safety monograph for STERILE WATER FOR IRRIGATION (STERILE WATER FOR IRRIGATION).
| Placental transfer | No significant placental transfer; water freely crosses placenta but without pharmacologic effect. |
| Breastfeeding | Sterile water is inert; no excretion into breast milk documented. Considered compatible with breastfeeding. |
| Lactation Rating | L1 (Safe) |
| Teratogenic Risk | Sterile water for irrigation is not absorbed systemically; therefore, no fetal risk is anticipated regardless of trimester. |
| Fetal Monitoring | No specific monitoring required for the drug itself. Standard maternal and fetal monitoring per clinical context of irrigation use. |
| Fertility Effects | No known effects on fertility due to lack of systemic absorption. |
■ FDA Black Box Warning
None
| Serious Effects |
None for sterile water for irrigation; contraindications relate to specific clinical use (e.g., avoid in irrigation of areas where hypotonic solutions may cause tissue damage).
| Precautions | Use only as a sterile, non-pyrogenic irrigation solution; do not use for intravenous injection or other parenteral routes, Do not use if solution contains particles or if container is damaged, May cause hemolysis if introduced intravascularly; avoid systemic absorption, Do not use for wound irrigation if prolonged contact with tissues is expected, as hypotonic solutions could cause cellular swelling, Not intended for use as a diluent or solvent for injectable drugs |
| Food/Dietary | No known food interactions as this is an irrigation solution not intended for systemic absorption. |
| Clinical Pearls | Sterile water for irrigation is used for wound cleansing, irrigation of body cavities, and during surgical procedures. It is not for injection, inhalation, or ophthalmic use. Use only if solution is clear and container intact. Avoid using large volumes for bladder irrigation to prevent water intoxication. For urologic irrigation, use sterile water for irrigation only if isotonicity is not required; otherwise, use normal saline to avoid hemolysis. Do not use in neurosurgery or other procedures where fluid absorption into systemic circulation is possible, as hypotonicity can cause hyponatremia and cerebral edema. |
| Patient Advice | This product is for external irrigation only, not for drinking or injection. · Do not use if the solution is cloudy or if the seal is broken. · Use only as directed by your healthcare provider. · Do not heat the solution unless instructed by your doctor. · Discard any unused portion after use as it contains no preservatives. |
