PRECAUTIONS
General: For ophthalmic use only. The initial prescription and renewal
of the medication order beyond 14 days should be made by a physician only after
examination of the patient with the aid of magnification, such as slit lamp
biomicroscopy and, where appropriate, fluorescein staining.
If signs and symptoms fail to improve after two days, the patient should be
re-evaluated.
If this product is used for 10 days or longer, intraocular pressure should
be monitored even though it may be difficult in children and uncooperative patients
(see WARNINGS).
Fungal infections of the cornea are particularly prone to develop coincidentally
with long-term local steroid application. Fungus invasion must be considered
in any persistent corneal ulceration where a steroid has been used or is in
use. Fungal cultures should be taken when appropriate.
Carcinogenesis, mutagenesis, impairment of fertility: Long-term animal
studies have not been conducted to evaluate the carcinogenic potential of loteprednol
etabonate. Loteprednol etabonate was not genotoxic in vitro in the Ames
test, the mouse lymphoma tk assay, or in a chromosome aberration test in human
lymphocytes, or in vivo in the single dose mouse micronucleus assay.
Treatment of male and female rats with up to 50 mg/kg/day and 25 mg/kg/day of
loteprednol etabonate, respectively, (600 and 300 times the maximum clinical
dose, respectively) prior to and during mating did not impair fertility in either
gender.
Pregnancy: Teratogenic effects: Pregnancy Category C. Loteprednol etabonate
has been shown to be embryotoxic (delayed ossification) and teratogenic (increased
incidence of meningocele, abnormal left common carotid artery, and limb flexures)
when administered orally to rabbits during organogenesis at a dose of 3 mg/kg/day
(35 times the maximum daily clinical dose), a dose which caused no maternal
toxicity. The no-observed-effect-level (NOEL) for these effects was 0.5 mg/kg/day
(6 times the maximum daily clinical dose). Oral treatment of rats during organogenesis
resulted in teratogenicity (absent innominate artery at ≥ 5 mg/kg/day doses,
and cleft palate and umbilical hernia at ≥ 50 mg/kg/day) and embryotoxicity
(increased post-implantation losses at 100 mg/kg/day and decreased fetal body
weight and skeletal ossification with ≥ 50 mg/kg/day). Treatment of rats with
0.5 mg/kg/day (6 times the maximum clinical dose) during organogenesis did not
result in any reproductive toxicity. Loteprednol etabonate was maternally toxic
(significantly reduced body weight gain during treatment) when administered
to pregnant rats during organogenesis at doses of ≥ 5 mg/kg/day.
Oral exposure of female rats to 50 mg/kg/day of loteprednol etabonate from
the start of the fetal period through the end of lactation, a maternally toxic
treatment regimen (significantly decreased body weight gain), gave rise to decreased
growth and survival, and retarded development in the offspring during lactation;
the NOEL for these effects was 5 mg/kg/day. Loteprednol etabonate had no effect
on the duration of gestation or parturition when administered orally to pregnant
rats at doses up to 50 mg/kg/day during the fetal period.
Nursing Mothers: It is not known whether topical ophthalmic administration
of corticosteroids could result in sufficient systemic absorption to produce
detectable quantities in human milk. Systemic steroids appear in human milk
and could suppress growth, interfere with endogenous corticosteroid production,
or cause other untoward effects. Caution should be exercised when LOTEMAX (loteprednol etabonate ophthalmic suspension) is
administered to a nursing woman.
Pediatric Use: Safety and effectiveness in pediatric patients have not
been established.
