General
The possibility of persistent fungal infections of the cornea
should be considered after prolonged corticosteroid dosing.
There have been reports of bacterial keratitis associated with the use of
multiple dose containers of topical ophthalmic products. These containers had
been inadvertently contaminated by patients who, in most cases, had a concurrent
corneal disease or a disruption of the ocular epithelial surface. (See
PRECAUTIONS, Information for Patients.)
Information for Patients
Patients should be instructed to avoid allowing the tip of the
dispensing container to contact the eye or surrounding structures.
Patients should also be instructed that ocular solutions, if handled
improperly, can become contaminated by common bacteria known to cause ocular
infections. Serious damage to the eye and subsequent loss of vision may result
from using contaminated solutions. (See PRECAUTIONS, General.)
Patients should also be advised that if they develop an intercurrent ocular
condition (e.g., trauma, ocular surgery or infection), they should immediately
seek their physician’s advice concerning the continued use of the present
multidose container.
One of the preservatives in dexamethasone sodium phosphate ophthalmic
solution, benzalkonium chloride, may be absorbed by soft contact lenses.
Patients wearing soft contact lenses should be instructed to wait at least 15
minutes after instilling dexamethasone sodium phosphate ophthalmic solution
before they insert their lenses.
Carcinogenesis, Mutagenesis, Impairment of
Fertility
Long-term animal studies have not been performed to evaluate the
carcinogenic potential or the effect on fertility of dexamethasone sodium
phosphate ophthalmic solution.
PregnancyPregnancy Category C
Dexamethasone has been shown to be teratogenic in mice and
rabbits following topical ophthalmic application in multiples of the therapeutic
dose.
In the mouse, corticosteroids produce fetal resorptions and a specific
abnormality, cleft palate. In the rabbit, corticosteroids have produced fetal
resorptions and multiple abnormalities involving the head, ears, limbs, palate,
etc.
There are no adequate or well-controlled studies in pregnant women.
Dexamethasone sodium phosphate ophthalmic solution should be used during
pregnancy only if the potential benefit to the mother justifies the potential
risk to the embryo or fetus. Infants born of mothers who have received
substantial doses of corticosteroids during pregnancy should be observed
carefully for signs of hypoadrenalism.
Nursing Mothers
Topically applied steroids are absorbed systemically. Therefore,
because of the potential for serious adverse reactions in nursing infants from
dexamethasone sodium phosphate, a decision should be made whether to discontinue
nursing or discontinue the drug, taking into account the importance of the drug
to the mother.
Pediatric Use
Safety and effectiveness in pediatric patients have not been
established.
Geriatric Use
No overall differences in safety and effectiveness have been
observed between elderly and younger patients.
