PRECAUTIONS
Hypotonicity
Sterile Water for Irrigation is
hypotonic with an osmolarity of zero mOsmol/L. It is intended for use as
irrigation fluid and not for intravenous administration or administration by
other, usual parenteral routes, such as intravascular administration in
general, subcutaneous administration, or intramuscular administration.
Serious adverse reactions,
including cerebral or pulmonary edema, massive hemolysis, and acute renal
failure can result from the hypotonicity of Sterile Water for Irrigation [see
Excessive Water Absorption].
Excessive Water Absorption
Due to the hypotonicity,
absorption of Sterile Water for Irrigation can result in serious adverse
reactions of hyponatremia, hypoosmolality and fluid overload, resulting in
fatality or permanent morbidity. Complications include cerebral edema,
encephalopathy, pulmonary edema, massive hemolysis, rhabdomyolysis, renal
failure, and hyperkalemia [see ADVERSE REACTIONS]. In addition,
excessive volume or pressure of the irrigation fluid may also cause undue
distension of body cavities and may cause tissue disruption (e.g., tears or
perforation). These complications can manifest after irrigation has ended and
immediate intervention may be required.
Monitor patients closely for
absorption of clinically relevant amounts of fluid during and for an
appropriate period after the procedure. If absorption occurs, discontinue
Sterile Water for Irrigation.
Additional close monitoring
during and/or after the procedure is recommended for patients at increased risk
for developing complications related to hypotonicity, such as:
- fluid overload syndrome, including patients with severe
renal impairment, impaired cardiac function, or other clinical conditions
associated with edematous states.
- hyponatremic encephalopathy, including pediatric
patients; women, in particular premenopausal women;
patients with hypoxemia; and patients with underlying central nervous system
disease.
Avoid use of Sterile Water for
Irrigation in patients with wounds where significant absorption may occur, such
as procedures that require irrigation over a longer period of time or an
irrigation fluid pressure that promotes absorption (e.g., transurethral
resection of prostate). Sterile Water for Irrigation should only be used by
clinicians familiar with the treatment of possible complications.
Use With Electrosurgery/Cautery
In contrast to other irrigation
fluids containing electrolytes, Sterile Water for Irrigation is non-conductive.
Therefore, when choosing the distension solution/fluid used with electrosurgery
or cautery, ensure compatibility with the equipment.
Use In Specific Populations
Pregnancy
Risk Summary
Appropriate administration of
Sterile Water for Irrigation is not expected to cause adverse developmental
outcomes. There are no available data on Sterile Water for Irrigation use in
pregnant women to determine a drug-associated risk of adverse developmental
outcomes. Animal reproduction studies have not been conducted with Sterile
Water for Irrigation.
All pregnancies have a
background risk of birth defect, loss, or other adverse outcomes. In the U.S.
general population, the estimated background risk of major birth defects and
miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%
respectively.
Lactation
Risk Summary Appropriate
administration of Sterile Water for Irrigation is not expected to cause harm to
a breastfed infant. There are no data on the presence of Sterile Water for
Irrigation in either human or animal milk, the effects on the breastfed infant
or the effects on milk production. The lack of clinical data during lactation
precludes a clear determination of the risk of Sterile Water for Irrigation to
a breastfed infant; therefore, the developmental and health benefits of
breastfeeding should be considered along with the mother's clinical need for
Sterile Water for Irrigation and any potential adverse effects on the breastfed
infant from Sterile Water for Irrigation or from the underlying maternal
condition.
Pediatric Use
Safety and effectiveness in
pediatric patients have not been established. Pediatric patients are at higher
risk compared to adults for developing encephalopathy as a complication of
hyponatremia, if there is excessive absorption of Sterile Water for Irrigation [see
WARNINGS AND PRECAUTIONS].
Geriatric Use
Sterile Water for Irrigation
should be used cautiously in older patients. Geriatric patients are more likely
to have decreased cardiac, renal, or hepatic function, and other diseases or
concomitant drug therapy.
